28 Years Later: Union VFX cracks complexity of iPhone filmed infected action

RedShark News

Danny Boyle shot almost the entirety of zombie horror sequel 28 Years Later on a iPhone 15 which succeeded in immersing the viewer in the heart of the gory, disorientating action at the same time as it presented technical challenges for the VFX team.

 

This was especially the case in sequences shot handheld with either a 20-camera or a 10-camera lightweight 3D printed rig arrayed in 2.76:1 widescreen aspect ratio. 

 

“Danny is driven by a kind of in-camera realism but when you're doing something as complex and ambitious as this with iPhones there's a lot of limitations we were perhaps the first filmmakers to encounter,” says Union VFX’ Dillan Nicholls who was DFX Sup on 28 Years Later working with overall VFX Supervisor Adam Gascoyne.

 

Union VFX have worked on previous Boyle projects including Pistol and T2 Trainspotting and because of that relationship knew the facility could handle what was thrown at them.

 

Boyle and cinematographer Anthony Dod Mantle not only wanted the mobility of the phone camera but leant into the aesthetic generated from the device’s limitations.

 

“It's not the most VFX friendly source media but that's not the look they wanted. They don't want that clean Marvel superhero look. That's exactly what they were trying to get away from.”

 

For example, many of the scenes of arrow hits were captured using the rigs. Union were tasked with rebuilding a scene from up to 20 cameras in post, match-moving each one of the cameras to get them aligned and synced correctly to match the edit before they applied VFX.

 

“If we're creating a CG arrow it was like having 20 shots in one and they needed to exactly line up. Any prep or compositing work that you're doing on one angle of those 20 has to ensure looks the same. It's like doing stereo 3D work where, you've got the two eyes. It needs to look the same from each of those 20 different eyes that you're going to see in quick succession, otherwise, it's kind of going to kind of bump.

“It's a bit of an unusual thing to do and our pipelines are not exactly set up to do 20 very fast cuts and make that into effectively one shot that works from multiple angles. Certainly doable but slightly odd and achieved through meticulous planning.”

 

The ProRes files meant that the team were dealing with chroma subsampling of 422, less information than is normally required for keying.

“It's very difficult to work with because there's less information in the colour channels. You’re better off with a green screen than a blue screen but still not very effective. So for the Causeway Chase, which could have been a big blue screen or green screen shoot, we used gray screens and roto.  There's other advantages to not using blue or green screens which also played into the decision but one of the reasons was we knew the cameras wouldn't cope very well with keying.”

Nicholls continues, “The sensors also offer quite a limited dynamic range. With the fire shots, it clips at a certain level and you can see that in the cinema. You can see that you're not seeing detail in the whites of the fire in the way that you would if it was shot on Alexa or on film. Our task was just to ensure that when we're adding our fire simulations we ensure that they're clipping and that they match the same quality that you get from the iPhone.

 

“It has a particular kind of noise and artefacts that another director or cinematographer would have asked us to remove but this was actually the aesthetic they wanted.  So all the VFX we put in can't look too clean. We needed to kind of break it. We needed to make sure it has the same limitations as the iPhone.

They found other challenges with using the iPhone. The metadata from the pinch Zoom didn’t feed through correctly into post. There was a difficulty too in matching the video’s motion blur which Union haven't fully understood yet.

 

“There were certainly challenges where we were mixing a lot of CG with live action where it would take quite bespoke work to get the correct matchup. The iPhone seems to constantly adjust some of these things internally.”

 

Dod Mantle wanted to use the iPhone auto-stabilisation feature. “It’s great for amateurs like you or I but it breaks the math of how you track cameras,” says Nicholls.

 

“We knew this beforehand and were able to advise Anthony that if he used auto-stablise there would be some limitations on what we can do. Basically, it breaks the image so that parts of the image slide around. Match move is a very much a mathematical process based on parallax. It's not like compositing where you can eyeball in. With match move it either works or it doesn't and if you start automatically moving pixels around without having a way to undo that then it gets difficult. We had to be very flexible and did find ways of working with it using multiple camera tracks at different layers and depths.”

 

Since then, Union VFX have been talking to Apple about whether they can provide that data. “We were honest about the areas that we struggled with if they wanted it to be used more frequently for visual effects.”

 

It’s possible that Apple might let users invert the stabilisation data so that a director and cinematographer can use the tool as they wish on set but it would be possible to then invert it, for VFX, then reapply back.

 

Union worked on around 930 shots but the total count is much higher. “Danny likes to keep everything going in the edit right up until the end. We certainly worked on more shots than are in the final edit.”

 

Holy Island (aka Lindisfarne) in Northumberland was the real life location for the survivors community in 28 Years Later. It even has a causeway, but it winds and curves, while used as the basis for photography the linear causeway in the film was a CG construction from photography at Bovingdon.

 

The casting of child actors, notably 13-year-old Alfie Williams playing Spike, limited film time – especially tight at night. It’s one reason why the nighttime Causeway Chase was staged in the studio. The set contained a 100-metre ankle deep water tank and the sequence contained around 130 shots

 

 

“We would get a lot of the water splash interactions as they're running through the water in-camera, but everything else was full CG water extensions.”

 

A lot of work into the night sky of this sequence too. Boyle’s idea being, what would the UK be like if there was no electricity and no pollution for 28 years?

 

“He was really excited that we create something with amazing kind of nebular skies. Our base reference were photographs taken at the Kielder Forest Observatory in Northumberland and added some reference images from the Hubble telescope of the Carina star birth nebula, so it feels hyper real and magical.”

Arrows were safety arrows drawn in the bow on set and then dropped rather than fired. CG took over the arrows in flight. Actors wore blood squibs to achieve a blood explosion on camera augmented by VFX.

They added flies to the deer heads and made them more gory and created the umbilical cord in the baby birth scene “but even here they most of that achieved on set.”

 

For a scene in a Happy Eater fast food restaurant they added layers of smoke. “You can generate some smoke on set to get feel for how it would look, but essentially we needed layers of benzene across the interior of that building and it’s not something that you're ever going to achieve practically doing multiple takes.

 

When the gas ignites in the Happy Eater, VFX augmented the stunt performers wearing protective suits, to look as if set on fire, or replaced them with digi-doubles.

A fox running out a cottage was shot in camera but two sequences of herds of deer and a murmuration of birds, were largely Union’s work.

“We wanted a Jurassic Park moment, giving that sense of nature having taken over the landscapes. It was a case of taking what was there in the photography, the shapes of the fields, and thinking what would that look like if the farmer had suddenly abandoned it.”

The actors and extras playing the infected wore prosthetics of body parts on top of shorts requiring significant cleanup of. “They're wearing shoes running around in the field so those needed removing or replacing. In sequences where they're wearing harnesses the infected needed a complete body rebuilds.

 

“These are maybe trivial or straightforward things but when you're talking about hundreds of shots and needing to paint out these costumes on several hundred extras that is a serious amount of work. It requires a lot of planning.

 

The island was a DMP (digital matte painting) environment. It’s a crucial story point, and the filmmakers were very conscious to establish its location in in relation to the mainland. “This explains why it's safe and why they’ve made a home there. This mean that the DMP asset couldn’t be just a one-off that you see from one angle where you can sort of fudge it. It's supposedly a 1.5 mile long Causeway so everything had to be mathematically correct in our asset build to enables you to then film it from whatever angle is needed to tell the story.

“Some of those angles are quite wide therefore, there's less emphasis on the detail, but then they would ask for a close-up. It had to be rigorously planned and designed to make sure that the components of set they filmed on Holy Island – such as the village gate, sat with our CG world. The mainland in the background in the real Holy island was too close for the story world so we had to push it back and get that sense of 1.5 miles distance.”

 

All of that work fed into the nighttime Causeway Chase, which is where the Alpha infected chases Spike and his Dad (Aaron Taylor-Johnson) back to the sanctuary of the island.

While production design, prosthetics and SFX created Boyle’s vision for the infected Union had creative input quite late in the process. “Danny decided he wanted to make the Alphas more menacing and less human. So we did a round of look dev, doing digital makeup effectively by graying that tongues and lips, creating bags under their eyes, reddening their eyes. Whereever, the larger infected appear in the film we applied that look by tracking those textures.”

An infrared look on some night time shots (ie where infected are feasting on a deer) was developed by Union with Boyle. “Not super complex, but I think really quite effective.”

 

Part two of the planned trilogy, 28 Years Later: The Bone Temple was shot back-to-back with this, is currently in post and due for release next January. It is directed by Nia DaCosta with photography by Sean Bobbitt.

 

Betting on homegrown AI

IEC Tech

How IEC Standards are helping India to become an AI powerhouse and jump ahead of the queue.

At the start of the year, the Indian government gave its electronics and tech sector a mission to develop the country’s first large language model (LLM). The artificial intelligence (AI) model, expected to be ready as soon as this winter, is part of a broader vision for the country to become a global AI powerhouse by 2047.

Key planks of the programme include the IndiaAI Mission, which launched in 2024, promising a budget of over ₹ 10,000 crore (USD 1,5 billion) a year to develop India's AI ecosystem through public-private partnerships. This builds on an earlier National Strategy for AI published by India’s public policy think tank to guide R&D in the emerging technology across healthcare, agriculture, education, smart cities and infrastructure.

The overall aim is to build standalone or sovereign capability in a technology which is seen as transformational across many sectors. “Unlike in the past, AI in India is no longer confined to a privileged few or dominated by global tech giants,” it argues. “[The] government is empowering students, startups and innovators with world-class AI infrastructure, fostering a truly level playing field, paving the way for innovation and self-reliance in this critical sector.”

Core to the strategy is for LLMs to be developed and hosted in India, tailored to work for the specific social, cultural and business diversity of its 1,46 billion people, who converse in 22 officially recognized languages. This approach is supported by Sovereign AI, a concept which refers to a nation’s capacity to be self-reliant by using its own infrastructure, data, workforce and business networks. In India’s case, the objective is to be competitive with China and the USA, which are currently leading the AI race.

Growing adoption of AI in India

India’s AI market is growing at a rate of 25-35% per year and is projected to reach USD 17 billion by 2027, according to a trade association for software and services. In a separate report, the association says it expects the broader technology industry in India to deliver USD 300 billion in 2026, driven in part by steady advances in AI, as enterprises expand their tech initiatives at scale.

Gnani.ai is one of hundreds of AI-focussed start-ups in India. “People are excited about AI and impatient to adopt it,” says founder and CEO Ganesh Gopalan. “Every board of every organization is putting pressure on their employees to use more AI in the workplace. It could be for cost reasons, to increase revenue or to improve customer satisfaction. Whatever the end goals are, I see a lot of interest in using AI in India.”

Anecdotally, there appears to be a lot less fear in adopting the tech than in western economies, which, Gopalan suggests, is partly because of the country’s rapid growth. “The question of AI replacing jobs comes less into the equation in developing markets like China and India compared to developed markets. In India, the discussions are always around return on investment (ROI). We are a nation culturally obsessed with ROI and that’s not necessarily the case in developed markets.”

Handling multi-linguistic complexity

Gopalan believes that Indian sovereign LLMs are a huge opportunity. He says global models like GPT (developed by OpenAI), Claude (Anthropic), Gemini (Google) and Meta (Llama), trained on largely English language and Western cultural databases, work less effectively in a country as diverse as India. “The world is not just one in which English is spoken. There are complexities within languages. So, when you translate global LLMs into other languages, they often fail because there isn't enough training data. The same is true for countries in Latin America or Africa. Even the basic things that global LLMs do for the US or the UK just cannot be done for many markets around the world.”

His company develops AI models from an India-first perspective. He explains, “The number of tokens [base units of text that LLMs use to understand language] that you would use for a typical LLM is very different when it comes to India. An AI model in Tamil or Telugu local language requires very different inputs and parameters.”

Gnani.ai has launched a speech-to-speech LLM that it claims can handle over 30 million voice interactions daily and supports 14 languages for businesses across India and the US. Speech-to-speech (or voice-to-voice) AI technology enables humans to converse with digital chatbots and other AI systems. As a subset of its LLM, Gnani.ai has developed small language models (SLMs) targeted at specific verticals, including the banking industry. It is in the process of launching another for insurance, with a retail model in the works.

“Every industry has a different vocabulary, phraseology, pitch and tone so in the context of customer management, for example, each will be different,” Gopalan says. Beyond addressing a specific audience with local and sector specific languages, the development of India-first AI models is also deemed important to counteract potential cultural bias, or lack of nuance, in global LLMs.

Addressing bias, a key concern

“It is incredibly important to take bias into account,” Gopalan adds. “Even without getting into the ethics of copyright, the first and most important component in your model is bias. It is a huge issue since you can’t ever be sure of the exact weight [or bias] on which a global model has been trained. You don't even know if it's biased until you use it. You can make an assumption, but basically, it's an unknown factor.”

A practical use case his company is trying to solve is to automate the underwriting of loans or insurance at a bank. “What if your underwriting process actually gave people loans they could not repay or unfairly denied people access to finance because the AI model had a bias? It’s not only highly unethical on your part, but it’s going to negatively affect your business.”

He advocates training models for corporations using the data they own and control. “These SLMs are not trained on trillion-parameter models [like LLMs] but on a few billion-parameter models that the [corporation] owns to make sure that biases are under control. That's why the concept of Sovereign AI is important. You can’t just write an application programming interface (API) for a global LLM.”

Gopalan says private industry, government and education are in lock-step in developing the country’s AI capability. “Educational institutions will adapt their course curriculum to include more AI components to feed demand from the private sector for jobs,” he explains. “Since AI is fundamentally software and coding, things at which Indians tend to be broadly good at, the future is looking good.”

Indian investment in education for AI

The government is building homegrown expertise to fuel research, innovation and the workforce in concert with multinationals. Mumbai’s Universal AI University, founded in 2023, was the first in the country to integrate AI across its curriculum, with the backing of a leading Indian IT company. A Fortune 500 company funded Mumbai’s Jio Institute (named after the multinational’s telecom division), including the Centre of AI for All, which advances “India-centric AI capabilities”. The Thapar Institute of Engineering and Technology has its AI programmes supported by an American computer processing giant. Another multinational is backing a training scheme to boost the AI skills of over 2 million Indians, and one of its leading researchers is working with the Bill & Melinda Gates Foundation to build “gender-intentional” datasets in five Indian languages that together are spoken by over 1 billion people.

Standards for responsible AI

As Gopalan made clear, an AI model is only as good as the data it is trained on, and bias can creep in, creating all sorts of problems, depending on the application area. International benchmarks which set guidelines to check the data quality and avoid any form of bias are a way of ensuring systems work efficiently and ethically. The joint ISO/IEC committee, established to develop standards in the area of AI, has published ISO/IEC 5259-5, which provides a data quality governance framework for analytics and machine learning to enable organizations and companies to direct and oversee the implementation and operation of data quality.

To identify and prevent bias in outcomes, the committee has published ISO/IEC TS 12791, which provides mitigation techniques that can be applied throughout the AI system life cycle in order to address unwanted bias. This document is applicable to organizations of all types and sizes .

AI is making huge strides in India. By favouring homegrown systems to compete with worldwide tech giants, India is rapidly becoming an AI force to be reckoned with. Standards can help it avoid some of the mistakes made by companies based in the USA or China, which started earlier in the race but initially lacked internationally recognized benchmarks to guide them.

 

Indian solutions for water scarcity

IEC Tech

article here

An Indian entrepreneur is promoting tech that recovers water from the atmosphere and from data centres. International standards are there to help him scale the technology further.

A teenage Star Wars fan may have solved one of the world’s most pressing problems of water shortage. Eighteen-year old architecture student Swapnil Shrivastav was enjoying George Lucas’ 1977 film when he noticed the vertical pumps called “vaporators” on Luke Skywalker’s desert planet, Tatooine, which were drawing water from the air. “In 2012, I was in my second year of college and we were doing a project called ‘Imagine the future of water and cities’, which asked for innovative solutions for water scarcity,” he explains. “The idea came from science fiction but when we investigated further, it seemed that we could actually make it happen.”

Uravu Labs, which Shrivastav co-founded in 2017 in Bangaluru, has raised USD 4 million to develop a means of extracting water from the air. The startup is one of a myriad of technology solutions addressing India’s challenging and complex water management.

Access to water is not guaranteed

The statistics paint a dire picture. Thirty five million of the country’s 1,46 billion population lack access to safe water, according to global nonprofit Water.org. It cites extreme water stress, contaminated surface water and lack of access to piped water supply, in addition to the impact from climate change, which is exacerbating the availability of safe water and sanitation for families in India.

UNICEF estimates that waterborne diseases cost USD 600 million a year in India, hitting people living in drought and flood-prone areas the most. A recent WHO report indicates that providing potable drinking water could stop 400 000 people dying from diarrheal disease. It adds that with universal coverage of safely managed drinking water, 14 million DALYs (disability adjusted life years) could be averted. “The stark reality is that, even after high rainfall, we still rely on groundwater,” says Shrivastav. The reason is that the water pipe infrastructure is far from universal, and in many places, piped water is also polluted. Instead, people have resorted to digging boreholes to tap groundwater.

UNICEF says the fast rate of groundwater depletion in India is one of the world’s highest, due to the proliferation of drilling. The World Bank predicts that, if current trends persist, at least a quarter of India’s agriculture will be at risk. “Agriculture in India is groundwater dependent and lots of domestic and even industrial uses are groundwater dependent,” Shrivastav explains. “But groundwater is not a renewable resource, and the deeper and deeper you go, the more it becomes unviable to tap into. There are places in Bangaluru where, even at depths of 1 500 ft to 2 000 ft, there's no groundwater.”

An alternative is to transport water over long distances in tankers to areas of the country which don’t have piped water supply or reliable groundwater. However, it is an expensive solution, forcing people to pay over the odds to access the resource. It is also environmentally questionable. “We wanted to find a solution which could solve two or three of problems at once,” Shrivastav indicates.

Drinking water from the air

Atmospheric water generation (AWG) is widely seen as one of the environmentally sound answers to water scarcity. The technology harvests moisture from the air, can be powered by renewable energy and, since the systems do not rely on traditional freshwater sources, can be placed where water is scarce. The global AWG market was estimated at USD 2,8 billion in 2024 and is expected to grow at a CAGR of 8% from 2025 to 2034.

Shrivastav’s company uses a hygroscopic desiccant to absorb vapour from the air, which is then heated to between 50-70 C° to release drinking water. Its standard unit fits into a 20-foot shipping container and can output 2 000 litres per day. Powered by renewable energy (such as solar) the operating costs are less than two cents per litre, making it 10 times more efficient than its competitors, Shrivastav claims. The “proprietary combination” of liquid silica desiccant it uses is “abundant, non-hazardous and costs less than one dollar per kg”.

Nonetheless, capital costs are high, and the cheapest model currently is priced at around USD 85 000. “The cost of borrowing is very high in India, even for established enterprise customers,” Shrivastav admits. “Interest rates are anywhere from 14 to 18%.” This means that local Indian communities with a water access problem cannot afford to take out loans to buy the containers.

The start-up is hoping to attract investors – either Indian or international – and is also looking for more funding from the Indian government, which in turn could help in producing the containers on a more massive scale and reduce their price.

In the meantime, the company switched its attention to more commercial applications, including selling renewable drinking water to hotels and restaurants in glass bottles, which it recollects after use. “It’s an alternative to the packaged water market, which draws on a lot of groundwater.”

Where standards and conformity assessment can help

Basing new or emerging technologies on internationally agreed standards can help to build trust in the investor community by ensuring they are safe and perform as expected. In the medium term, standards will help to bring down the price of newly launched products and also ensure that they can be exported to other countries.

For example, the IEC publishes most of the standards relating to renewable energy systems, from solar photovoltaic (PV) panels right down to tidal energy conversion. All the solar PV standards are published by IEC Technical Committee 82 and include the IEC 62257 series of technical specifications which make recommendations for small renewable hybrid systems, involving, for example, a solar panel and a battery. They have been recognized by the World Bank and the United Nations Industrial Development Organization (UNIDO) as an important contribution to electricity access in remote and deprived areas of the world and can be used as a blueprint to power solutions like those promoted by Shrivastav’s company.

IECEE, the IEC System of Conformity Assessment Schemes for Electrotechnical Equipment and Components, offers a scheme for solar PV panels, which gives access to qualified testing laboratories for the certification of PV components and modules in accordance with the relevant IEC International Standards. IECEE PV certificates demonstrate that all elements and components are designed, manufactured and tested according to IEC Standards, ensuring compliance with quality and safety requirements worldwide.

The company is also developing a product which captures waste heat generated from data centres to produce water and uses that water to cool down the servers. Pilot projects are being set up in India and the Middle East. “Data centres can cut down on their cooling cost and also become the infrastructure which produces water rather than consuming it,” Shrivastav says.

That is where the work of one of the ISO/IEC joint technical committees, JTC 1/SC 39: Sustainability, IT and data centres, comes in. Its key publications include ISO/IEC 30134-1, which defines common requirements for a holistic suite of KPIs for data centre resource efficiency, including the use of cooling water and the recovery of energy.

The company plans to double operations in Bangalore this year to output 8 000 litres per day and to launch factories in two more Indian cities, targeting the hospitality sector. Additionally, it is developing an industrial-scale unit capable of generating 30 000 to 50 000 litres per day.  Shrivastav is hopeful about the future: “If, instead of making 10 or 15 units a year, we make a thousand units per year, it can drastically reduce capital expenditure. If we can also find better local financing, then a village in South India would only have to pay for maintenance because the running costs are very cheap, especially if paired with solar. Then it becomes viable.”

 

 

Behind the Scenes: Jurassic World Rebirth

IBC

The VFX blockbuster opts for an old school production by shooting extensively on location and on film

article here

Director Gareth Edwards returns to Thailand after filming The Creator there for another science fiction but this time with a far bigger budget and a decision to shoot on 35mm in order to recall Steven Spielberg’s 1993 franchise starter.

Universal Pictures’ Jurassic World Rebirth starring Scarlett Johansson is the seventh in the series and has a reported $265m budget, three times that of The Creator which was shot mostly on Sony FX3.

While Jurassic World: Fallen Kingdom had been shot by Oscar Faura using digital cameras, and Dominion shot by John Schwartzman was primarily captured on film, Edwards’ film is entirely shot film by cinematographer John Mathieson (Gladiator) and in manner which harks back to classic location pics of the 1950s.

“Gareth immediately asked me, ‘If you were to reshoot the Spielberg Jurassic Park now would you  shoot it on film?’ Absolutely, I said. I've been dying to shoot something on film again since Pokémon Detective Pikachu (2019).

Mathieson noticed the recent trend of a higher ratio of Oscar nominated films that are shot on celluloid compared to the number of digitally shot movies overall. “This reaffirms my suspicions that anyone can work a digital camera,” he says. “I don't think they're that difficult. You've got lots of people who will look after you on set and the cameras have got almost too much latitude. There's no real decision making with those damn things. With film you are working in stone. If you screw it up, you screw it up.”

Edwards has a reputation for using DIY techniques and agile camera gear in making films like breakthrough hit Monsters. “It struck me as interesting that he’d gone for a potentially more cumbersome route to shoot this project,” says Mathieson. “Film cameras are the weight of labradors.”

Film discipline

There was some resistance to shooting on negative even though executive producer Steven Spielberg has yet to convert to digital in his own movies. “We had to prove that we'd be responsible and shoot within budget of 22,000 feet a day which we never got near. We were down at 6000-7000 ft a day.

“When you shoot on digital the temptation is to let the camera roll and roll,” Mathieson says. “You’d even shoot the blocking, even though you know it’s going to be wrong. In a film like this it makes no sense to spray the cameras around and shoot everything. I mean, our screen is going to be filled with dinosaurs and clearly you’re not capturing them in camera.

“You're actually saving money because you're not doing overtime. You haven't got a bunch of DIT guys running around transferring data and doing the layoffs. These calculations don’t really come out on paper but I think producers and accountants should realise that shooting film can be more economic than digital, provided you are disciplined.”

Mathieson shot Kodak 500T and 50D 35mm with Panavision E and C series older anamorphic lenses, a simple camera package that he says harks back to how films were shot in the 1990s.

Principal photography between June and September 2024 visited Bangkok as a backdrop for some urban sequences and Thai coastal regions of Trang, Phang Nga, and Phuket for exotic and jungle settings. The Huai To Waterfall at Khao Phanom Bencha National Park, Krabi also features in the movie.  Greenwich University played a role in establishing the film’s setting. Additional scenes were shot in Manhattan’s DUMBO (Down Under the Manhattan Bridge Overpass) area.

Location location location

“People don’t tend to go on location any more. Not truly. We want on lots of recces, dealing with more old-fashioned logistics rather than popping along to Leavesden and a bunch of green screens.

“How do we get in there and what's the monsoon doing? Will the road still be there, or do we have to build a bridge? Are we going to get the trucks in and should we lay down sand ladders if they’re going to sink.

“The only way to do an epic movie was to go somewhere fantastic. We were in Thailand with amazing limestone stacks and deep heavy jungle. Trees wider than this room. Massive things. All the  holiday makers disappeared [because the tourist season ends in the spring] which was great. But then the weather came.”

He says, “Thailand's great if you go from the beach to the bar to the sea and back to the bar but if you go into the interior its tough. The jungles are spectacular and beautiful. Everything's overscale.
The palm fronds appear to be 30 foot long. There’s bugs. There's snakes. Big spiders. Lots of nasty diseases you can pick up. You're always wet. You're always sweating. Your feet are rotting. It was old style in that you go somewhere with a camera that people don't really want to go to you. You go around the bend of the river that no one goes around.

“We lived in the jungle, on some islands, then some caves that were full of bats. We had a Batman come to get rid of the bats because they are rabid. There's bat shit everywhere. Our crew came down with dengue fever, yellow fever, even cholera.

“We had a snake guy to get the snakes out of the jungle which is so absurd it's like trying to get worms out of a potato patch. Then the snake guy got bitten, so he disappeared.”

Mathieson recalls this with humour. He clearly enjoyed the experience as part and part of the rigours of filmmaking, much like Werner Herzog literally having his cast and crew haul a boat over jungle and mountain for Fitzcarraldo.

Feeling the heat

Even for the scenes set at sea they shot from two boats in the Mediterranean, as well as filming in large water simulation tanks at Malta Film Studios.

“We’d much rather experience the humidity and the sweat and toil to put it on film rather than doing it on a green screen or on a volume stage,” he says. “Even on this film we had bad weather and I got the wrong film stock at the wrong time but I’ve built up experience of being in the shit before, right back from making documentaries. If you had the wrong stock then you had to improvise. Push the stop. Open the windows. Shoot wide open. Anything you can to make it work.”

He says he partly got into the film industry for the adventure - “for going around the bend in the river to see things that tourists wouldn't see otherwise. I remember seeing Man with the Golden Gun in a crappy old cinema on a rainy November in suburban London and thinking I have no idea where that place is but I want to go there some day. Filmmakers went to beautiful places, photographed them and presented the wonder of the world back to cinema audiences at home.”

He thinks too much production these days is “unadventurous” in sticking to blue screens at home.  “Even though [this shoot] was ugly, difficult and hard work I still believe you get better results if you go somewhere for real. You can take people there.

“Some of the shots we have of the jungle in this film are designed to be spectacular when you see them in a cinema. Enormous leaves. Huge fronds. Towering waterfalls, burbling rivers, massive banyan trees. It feels real because it is. You couldn't build that in a stage.

“When we try and double it back in London [at Sky Studios Elstree] with foliage or a banana tree it’s a banana tree from a local nursery and it’s tiny. Even though you have great production designers you can't actually get that feeling of size, scope or sweep that you get from filming on location. We have some big deserted vistas so you really feel you're on this magical island in the middle of nowhere.”

It didn’t all go according to plan. Mathieson thinks they shot in Thailand at the wrong time of year. “We went from using some 5205 to fast Tungsten stock because it was so dark in the jungle. The canopy does it’s job very well if you’re a plant. Every little leaf is looking for a bit of photosynthesis. And if you've got no sun, you don't get lovely spaghetti stripes, you just get great sludge.”

They did “struggle” to bring in some lighting equipment but the DP says this didn’t offer much help. “You can put a bit of brightness in the background to offer some depth but you hope for a clearing or a fallen tree so you have a bit of contrast somewhere. I'd preferred it if we'd shot earlier in their winter with clearer skies and the sun beating straight down on us and we’d put in smoke to look like
jungle mist and steam.”

Even in humidity and temperatures of 100F in Malta the film camera survived.  He says, “Film cameras don't mind getting wet because once you load that film and close the door they are waterproof.  They don’t have fans to cool them down. If we'd shot digital, we’d be wrapping them up to keep it dry. With all the tropical rain I'm sure we'd have overheated them. Digital cameras don’t like moisture or dust and Malta has to be the dustiest place in the world.

“Film cameras are very user-friendly in tough situations where I think digital cameras would have failed. They’re more like Land Rovers. Built tougher.”

“Everyone loves a dinosaur”

Mathieson says the Spielberg was very involved. “He was speaking to Gareth every day and he’d give us notes on the rushes. He’d say ‘this is a bit dark’ or ‘this is too close-up’. You have to realise that Jurassic Park is his baby. He has had astonishing success but Jurassic Park might just be his biggest. It’s as big in terms of audience fandom as any Marvel or Star Wars project.”

The DP who has worked with Ridley Scott, Guy Ritchie, Joe Wright and James Mangold says he was drawn to the project as much by wanting to work with Edwards as to have his own stab at making a summer blockbuster.

“Gareth’s fantasy and science fiction films have a freshness. As a viewer you feel more in his pictures than you would in some of these other Godzilla King Kong space movie. The way he introduces monsters or dinosaurs is almost casual. You just feel that's the way it would be so you believe it more.”

Mathieson’s main regret is that they didn't use many animatronics with ILM taking charge of dino VFX. “That's one of those things that you mourn about the digital age because the days of big special effects are dying out,” he says.

Spielberg’s original movie is famously the first blockbuster to give generous screen time to CGI creatures but it also used a lot of practical effects, such as the T-Rex head and eye glaring into a jeep full of petrified humans.

“The mechanical effects make it feel much more present. It’s why the original is such a favourite. That said, everyone loves a dinosaur. Every kid loves dinosaur. And ours are enormous.”

Esports World Cup plans biggest video game tournament ever staged

IBC

Returning to Riyadh this month for its second outing, the Esports World Cup is being billed as the most ambitious and technologically advanced global competitive event in history.

article here

With 25 tournaments across 24 games and 200 Clubs from over 100 countries, the EWC will feature the largest prize pool in esports history, over $70 million.

“It's monumental. There is nothing like it,” says Mike McCabe, COO, Esports World Cup Foundation. “Most other esports events are built for a week or less of operation. We're talking about seven weeks of operation on a scale that is of an order of magnitude greater than anything else in esports.”

In the first week beginning July 7, for example, the four venues will host the group stage games of Valorant, Dota2, [sim racing game] Rennsport, Fatal Fury and Apex Legends building to play offs and then finals.

“If you imagine we're building the equivalent of a traditional three day Esports event but we're doing that in four different venues simultaneously for seven weeks in a row.”

McCabe is a former head of digital for Nike, senior exec at Electronic Arts and managing director of international publishing at Epic Games who joined EWC to build on the inaugural event.

That saw 250 million hours of content streamed across 21 different games to 500 million viewers. The League of Legends hit a peak viewership of 3.5m during its grand final, according to organisers. The EWC also claim that over 2 million people attended the event in person last year.

“There have been lots of singular gaming events around the world but this one is unique in bringing it all together,” says McCabe. “That's important from a broadcast standpoint because it enables us to create an economy of scale when it comes to the technology we're building into the venues. We can aim for a far wider audience than traditional Esports events where they're focused very much on an endemic Esports community.”

He says, “The only way we can elevate esports is to go as broad as we can within the gaming ecosystem both from a genre perspective and also from a geographic perspective.”

He also aims to increase “esport literacy” in order to reach audiences less familiar with the intricacies of first person shooter Call of Duty or battle royale formats Free Fire and PUBG Mobile.

To achieve that objective, linear broadcast is an important component. KSA broadcaster MBC took all the games live last year and is likely to do the same this time out. The event will be live streamed over Twitch and YouTube and also by some of the game publishers “within their own ecosystem.”

There are also a larger group of content creators or “co-streamers” on site delivering content to their followers on social platforms.

“They have that connection with their audience so for us to be able to broadcast to that full gaming community is incredibly valuable from a co-streaming standpoint,” says McCabe. “It’s very important for us to reach out beyond all the traditional streams.”

One of the key lessons from last year was that more needed to be done to make mainstream audiences feel at home with esoteric to gameplay.

“We found latent appetite to understand more. People are inquisitive. They keep hearing about esports and they want to know more but the core content that we create from a game stream doesn't have enough explanation or enough entertainment content. We're creating a new broadcast product that we will be trialling this year to specifically target that more mainstream audience.”

While there a lot of similarities with traditional sports broadcasting there's also a lot that's different.
“There's no one party that has that skill to be able to span across all of the different pillars,” says McCabe. “It is much more of a first party and very game specific because there are specialists at the publishers who really understand a particular franchise. The crew supporting EA Sports FC are very different from the people supporting League of Legends. But having that in-depth understanding of the intricacies of the game and what action should be focused on screen is vital

“It's a little easier perhaps with EA FC because the action is where the ball is but for a game like Tekken 8 or Starcraft II, where the strategy is often happening in different parts of the screen, you want to take the fans and the audience there too.”

While camera operators in the venues covering fans in the stands will span all of the different game many of the producers and technicians in charge of a particular esport production will rotate in and out based on their specialty.

The competition is facilitated by ESL Faceit Group (EFG), a division of esports’ event organiser ESL and a subsidiary of Savvy Games Group – itself owned by the Saudi government’s Public Investment Fund.

EFG is integrating the studio-based infrastructure capable of taking in all of the live feeds into the main control room as well as the technology on the venue stages, such as LED screens.

Vlad Petrescu, EFG Executive Producer EWC 2025 explains, “Each stage has multiple production lines that interact with one another. It starts with In-game production, which shows the match and directs the observers. Then comes Stage production, which handles the stage show and big moments like player reveals. From there, our English, Arabic, and Chinese teams take the feed and add localised content like match analysis and custom video assets.”

All production lines are equipped with Grass Valley vision mixers, EVS media servers for replays and playout, Lawo audio stations, and 2110 IP distribution.

Although each venue is host to multiple different games and the stages are dressed with different layout and presentation, the basic broadcast infrastructure remains consistent. Every gaming station across all of the different stages features player-based cameras from Chinese PTZ developer OBSBOT which have the ability to dynamically track movements. OBSBOT is also supplying its Tiny 2 webcams.

McCabe says, “We're going to test some features at the beginning just see if they work because there's a lot of gesture controls that are able to recognise player actions but these actions will differ according to game and even individual player. These cameras will give us really high quality player-based feeds that we can then use whether in venue on the LEDs or pull into the live stream.”

Another key objective is to make the EWC a destination and “repeat draw” for people in the wider Middle East. “That’s why the supporting events as part of the Festival are so important and why will rotate fan engagement activities each week. It’s the reason the EWC will be rotating games in venues over the seven weeks to give people a different reason to come in week one and return in week four based on the games that they're passionate about. That is a massive differentiator from my perspective.”

Alongside multiplayer games like DOTA and Rainbow 6 Siege, online chess makes its debut at the event with a huge $1.5m prize pool and world number one Magnus Carlsen leading one of the teams.  Also helping influence sports fans outside of the esports bubble is Saudi resident CR7. Cristiano Ronaldo is an ambassador for the EWC even appearing as a playable character in Fatal Fury: City of the Wolves, one of the tournament’s official games.

Another piece of brand marketing is a five-part docuseries chronicling the EWC 2024 and providing background stories to players. Level Up, from Oscar nominated director R.J. Cutler and his team at This Machine Filmworks, is currently streaming on Amazon Prime Video.

McCabe explains that the Esports World Cup is divided into two ‘products’: the Club Championship which is where gamers compete in teams in one of the xx tournaments. The club that generates the most points is crowned Champion. Running in parallel is the Festival, described as “a celebration of everything that is gaming from cosplay to education to influencer content creators.”

This area of Riyadh also includes live music, retro arcades and cafes. The tournament is played played over 7 weeks this year, as opposed to the 8 weeks of 2024, with the addition of a fourth stage accommodating an increased number of games. The number of competitors rises from 1500 to between 1600 to 1700 this year.

The EWC is intended as an annual event and would also run parallel to an Olympic Esports which is planned to be held every two years, also in Riyadh. The KSA is busy constructing a dedicated entertainment, sports and video gaming city called Qiddiya in the southwest of the capital.

“We will ultimately end up there, but that is scheduled to be completed closer to 2030,” McCabe says.

BBC goes hybrid for coverage of UEFA Women’s Euros

The 2025 UEFA Women’s European Championship kicks off on July 2, as reigning champions England defend their title and try to become just the second nation to win back-to-back Women’s Euros.

“England going in as defending Champions has really increased the attention on the women's team,” says BBC Sport executive producer Phil Bigwood. “It’s Wales’ first ever major tournament, so we've got strong focus there as well. The Euros is the centrepiece of the BBC’s women in sport season on top of the Rugby World Cup and Athletics.”

England’s win over Germany in Euro 2022 final pulled in a peak audience of 17.4 million on BBC One.

“We’re all aware of the growth in the women's game since England won last time. The way things have moved on are pretty unprecedented. Let's hope England can get out the group and we can we get close to those figures again.”

The BBC is exclusively showing three of the four quarter finals, as well as one of the semi-final fixtures and the final on Sunday 27 July, live on BBC One and iPlayer, as part of its 15 match allocation. ITV has another set of 15 and both share broadcast of the final.

Women’s Euro 2022 winner Jill Scott and Champions League winning manager Renee Slegers are joining the BBC’s line-up alongside seasoned presenters Gabby Logan, Alex Scott and Jeanette Kwakye.

Planning began in earnest about 10 months ago.

“First and foremost a lot of planning comes down to budgets,” says Bigwood. “Where can we get the biggest bang for our buck? Switzerland isn't the cheapest country in Europe so we've tried to prioritise where we can around covering the home nations.”

The approach is split between having a remote presentation from a virtual studio on the site of key group games involving England Wales in Switzerland (with plans for the quarterfinals onwards) and all other games to be produced from Quay House, Salford.

The host feed is being produced in 1080P with surround sound by Uefa which is using its established campus in Nyon, outside Geneva, rather than building a temporary IBC.

As luck would have it from a British broadcaster perspective, the majority of the match directors are English including the BBC’s own regular matchday director Andrew Swift and is Sarah Cheadle from Sky Sports.

Sunset+Vine won the tender to produce the TV output for the BBC at the end of 2024.  “We knew from day one we would want an indie to produce it. The fact that they are based with BBC Sports really helps us with all the multi-platform content with digital and the radio teams. There's a lot of crossover and sharing, which might not have been the case if we'd had a different setup.”

The BBC is taking in eight IP feeds from the host broadcast, via the Eurovision Services Content Hub, managed by S+V.

“Eurovision are used to distribute the Champions League which very conveniently the BBC have started taking as of last season, so that connectivity was already in place,” explains Mark Dennis, director of technical operations, Sunset Vine.

The feeds include a main and backup match feed, reporter cam, ISO cams and a clean backup. As part of belt and braces redundancy there’s a satellite backup too.

“There’s a dual fibre path and a satellite backup to bring in the main feed so that gives us access to a lot of feeds when we are not on site,” says Dennis.

Timeline TV is hired for the remote production travelling an OB truck between venues for on-site presentation. “Two data circuits have been booked from Eurovision from each of the venues that we may end up in, depending on how England and Wales progress through the group stages,” Dennis says. “These go to Telehouse North (data centre in London) and with help from BBC technology we have then piggybacked onto existing BBC connectivity up to Salford.”

A remote interface unit is installed in the Timeline truck which dovetails remotely with a Timeline rack at Salford. The presentation from the truck will be covered with six cameras.

“That also allow us do some ISOs ourselves, for example if our commentators or on-screen talent want to focus on a particular player, we've got our own big lens camera for close-ups of that player or particular area of the field,” says Stephen Booth, executive producer, Sunset Vine. “That gives a bit more flexibility in production.”

“From Sunset’s point's point of view we pitched in November midway through the Euro’s playoffs. It is actually a S+V Scotland production. We confidently told the BBC that Scotland were going to qualify. We got that wrong. But we're still here.”

Back in Salford, the post-production team will work from four Avid suites to clip and publish to various different platforms. This is done in conjunction with Picture Shop, the facility that provided a similar job to the BBC’s Paris Olympics efforts.

The main virtual studio, designed by Lightwell, is described by Booth as “a deluxe Swiss Chalet on the banks of Lake Lucerne. It features an exact replica of Lake Lucerne in the virtual environment behind it.

“That’s our main studio area. We also have a downstairs green room represented as well. We have virtual screens to conduct two-way interviews and analysis.”

We've got a lot of learnings ourselves at Sunset+Vine from designing a virtual setup at Ealing eating Broadcast Centre for the Amazon Prime Every Game Every Goal Premier League programme. This studio is next generation and has AR capability. We hope it’s going to be striking and impressive.”

Alongside cost, sustainability was at the forefront of planning. “It’s the reason to go with remote productions,” Bigwood says.

Crew are travelling to the country on Eurostar as much as possible. “There's a lot of logistics. And Switzerland's not the easiest places to get to sometimes,” says Tracy Van Ross, production executive.

ENG crews with LiveU packs will cover the Wales and English camps. A BBC Wales crew is covering the Welsh camp and also looking after S4C Welsh language coverage.

Sustainability is also a key theme for BBC editorial as well. “For example, we’ve got pieces planned about the stadium roof in Zurich (where England's group match versus the Netherlands takes place)
which has a wildflower meadow on it to aid the journey of bees coming from the mountainous areas in Switzerland,” says Booth. “One of the Welsh players is writing a thesis about sustainability and football which we're going to explore more deeply.”

In previous recent tournaments the technical resources have been shared with ITV but that’s not the case this time around. In part this is because there is no independent IBC

Bigwood says, “The majority of our sharing with ITV, whether it be feeds or space, is because there's been an IBC. In addition, while we’re in Salford they've got a different approach from us in London. So it’s not as straightforward to share, as we have done in the past, but there's been various conversations along the way.”

The broadcasters did however share access to time with the teams prior to kick-off at St George's Park in which squad players were filmed in their full kit for repurposing into TV graphics.

This is a much smaller event than the FIFA World Cup next summer which will host 78 matches. While there is little that can be taken into USA, Mexico and Canada from Switzerland as a template, the BBC will be taking note of tests by BBC R&D to reduce the delay that live matches take to reach iPlayer versus its broadcast channels.

“It's actually quite a big focus as we look ahead to the World Cup,” says Bigwood. “Because of the time differences and number of matches more people are going to be consuming matches on iPlayer. It's a big priority of the BBC to try and bring [delay] down.”

Bigwood suggests Switzerland’s work in time directive, which protects the hours people work, has been “something to contend with and plan for” but that it’s all been a smooth process. “We'll find out in a few weeks’ time,” he adds.

BTS: Tour de France

IBC

How wind tunnel data, official route topography, multi-screen live feeds and 21 daily outside broadcasts bring the most brutally mountainous Tour De France ever to fans on their sofa.

article here

The 112th Tour de France begins on Saturday, July 5 in Lille with 22 teams and 176 cyclists covering 3,338.8 km over 21 stages six of which are hilly and six classified as mountain stages including an individual time trial which finishes on a mountain summit.

Those might be the bare facts but it doesn’t begin to tell the story of the herculean effort of the athlete’s toiling up hills most of us would give up on within a metre, nor of the travelling circus that constitutes the tour’s organisation and media coverage.

This is last year that the Warner Bros. Discovery owned broadcaster shares rights in UK with ITV. From 2026 it will have exclusivity.

This year TNT Sports has linear coverage of every stage in the UK and Ireland. Eurosport will deliver linear coverage of every stage across Europe; every stage is streaming on HBO Max and discovery+ is streaming every stage in the UK, Italy, Germany and Austria ahead of HBO Max launching next year.

The host broadcaster is France TV working for Tour organiser Amaury Sport Organisation (ASO) with technical provision subcontracted to Euromedia Group (EMG).

TNT Sports takes the clean feed and the dirty feed which is produced by France TV and EMG, plus the six isolated feeds from motorbikes covering the peloton and feeds from two helicopters which circle the route.

New for this year’s Tour from TNT Sports is a second screen experience available on discovery+ in a quad screen format.  The multiscreen format debuted for the Giro d’Italia and gives constant coverage of one heli feed and three motos.

The feeds are brought into TNT Sports’ gallery containing a video and audio switcher and replay functions. “We produce that with commentary so viewers are always getting the front of the Peloton, the mid of the Peloton and the back plus the heli feed,” says TNT Sports Head of Cycling Guy Voisin.

TNT Sports also has a unilateral motorcycle feed in amongst the Peloton, the feed from which is also delivered alongside the host feed and muxed by EMG.

Currently viewers are unable to select one of the quad views and play it full screen. “It’s strictly a platform limitation on D+ but we we're going to be able to do it from next year on HBO Max,” Voisin says.

“There are two reasons to do this. The first is for super fans who gets to watch images that they may not see in the host produced version. We know from Giro d’Italia that super fans are watching. It’s not a huge amount, but we're in the percentages.

“For example, in a time trial instead of just the helicopter we can offer a motorcycle following individual riders. If you’re a fan of a Norwegian or Greek rider you can follow them from start to finish and not necessarily rely on the production feed who may think that the French or English riders are more important and cut to them more.”

It also helps explain the story of the race when the peloton, leaders and stragglers are split along way apart.

Additionally, the race teams themselves are able to view the multi-screen and react more quickly to events on track then would be immediately obvious from just seeing the traditional host broadcast.

TNT Sports trailed the concept during Italian race Strade Bianche sharing the ISOs with 13 of the 18 World Tour teams. “For them the importance was, they were able to see an incident happen in the race and report it back to their chase cars 90 seconds before they would have seen it on the broadcast feed. They’re able to judge tactics and the safety of the race. We offer it to all the teams so it’s equal.”

A prime example during the Gira was when a sporting director of one of the teams messaged Senior Cycling Producer Doug Ferguson to say he was watching the quad split in the chase car when one of their riders had a fall.

“It was a minor fall but the incident wasn't shown in the world feed because it happened in the middle of the Peloton (not affecting the race leaders),” Ferguson explains. “Because they were watching the quad screen it meant that their mechanic in the back of the car was ready straight away to fix a new wheel and get the rider back in the race quicker than normal. That, they said, was fantastically helpful. It probably saved them two minutes of race time.”

21 OBs and a moving town

The RF technology that EMG provides has improved to the point that there are rarely issues with signals dropping.  Signals from the motos are broadcast to a plane circling at 26000ft and received by its onboard satellite. This is retransmitted back to the TV compound on site where there are two antennas (main and back up) that are constantly tracking the plane for the best signal.

“The only real dropout is where we get incredibly bad weather or when they're going through a tunnel,” Voisin says.

The host feed is effectively a production of 21 different outside broadcasts in which the TV compound moves from stage to stage over three weeks. “It’s a moving town every single day,” says Ferguson. “It's a sight to behold. It's at least 4000 vehicles (teams, media etc) on the road. Each official vehicle is allocated a number and I’ve seen numbers over 9000 on the road.

“The guys who put the barriers out in the last 3K drive through the night to get to the next finish town, set them out then sleep all day. They don't see the race.”

TNT Sports receives its ten signals at one of two tech hubs at Hilversum and London’s BT Tower. There it is demuxed and enters the TNT network as IPTV which is then manipulated into unilateral feeds for 47 countries.

A number of countries have their own TNT Sports’ production wrapping around the race, among tem Spain, France and the UK. A team in Paris produces the ‘pan feed’ for countries that don’t have a local production. This is a multilingual feed produced in 19 different languages.

The UK show is presented from The Curve at Stockley Park Studios where Ferguson is senior producer. He also helps develop different analytical techniques, several of which are new this year.

For example, with Italian time trial specialist Filippo Ganna, who rides for Ineos Grenadiers, TNT Sports gained access to wind tunnel data from the testing Ganna made in April for a slightly tweaked riding position.

“Basically, he had his hands slightly lower down on the handle bar which completely changes the aerodynamic profile,” Ferguson explains. “We convert that raw data to explain why the teams take so much time and effort to use expensive wind tunnels and find 10 watts of difference, which could be the difference between first and second place.

“We recreate this data with all the coefficient drags and air particles showing the air flow over the rider in different positions. We can show how different riding positions can make a critical difference in time on the course.”

During the coverage, ex pro cyclist Adam Blythe can use the graphic to explain why, when the rider is in a lower position, they could hold it for a longer time.

“We take highly complex science and make it understandable and functional which for the Tour is vital because the aim is to attract new fans,” Ferguson says. “This is the sport’s Ryder Cup or Lions Tour or Grand National. It’s the event that everybody watches who doesn't normally watch pro cycling.”

Original data for meticulous storytelling

TNT also got access to wind tunnel tests with double Olympic champion Remco Evenepoel last November in California. He was working on a position for a mountain time trial (which features in the Tour this year).

“His position was really low on the bike,” Ferguson says. “He's like a blooming eel. Highly wind resistant but for a climb when the bike is at such a steep angle his normal riding posture was restricted. So, they were trying different positions to get him higher on the bike. While they were trialling that, they realised that his hands were bumping off the visor of his helmet – so they cut a piece out of the visor out and eventually got him to a position where his hands are right up to his face but he can still see.

“We're going to use that wind tunnel information to explain it in presentation - none of which we could do if we were just in a normal studio.”

All the top riders post some elements of their data although many won’t reveal their weight so as not to give too clues to the opposition.

Voisin says the teams are understandably a bit secretive about some of it. “At the same time, they are dealing with the recent history of cycling which is not always pretty. The more they can explain their speed and their preferences in a fair and technologically advanced way the better it is for the sport. They all understand this.”

He continues, “We’re in constant discussions with the teams. They give us good access. They’ll let us into team buses and wind tunnels. This is a lot to do with how we share back with them.”

Since 2023, TNT Sports has given the teams three minutes of bespoke video content. Voisin explains, “Whenever we own worldwide rights for highlights [and it has the rights to two thirds of the 300 pro cycling races worldwide] we give them three minutes for their social media. That helps us because they will promote our wider coverage but they also give us access because we're giving them something back. We have the rights, you guys are the gladiators, here's a little something back in exchange for putting on a great show. They have opened their doors much wider than ever before and specifically in the last year.”

The Tour makes available data about power, cadence, speed and heart rate but these are a fraction of the amount of sensors the athletes’ wear. Most data is restricted. The Jumbo-Visma team, for example, have a shirt which contains a breathing sensor revealing information about the exchange of oxygen in the blood.

“They pull that data off it in real time but use it internally since during the race it could be very determining,” Voisin says. “There are sensors that can determine when an athlete is low on blood sugar and therefore a good time for the opposition to attack. These sensors have been banned. The UCI is working very hard at making sure that nothing can be taken out of context to affect the race.  We have limitations on which sensors we can use in the race right now.”

“You can even get stress and strain levels out of the WHOOP data [a wrist worn sensor that captures data on an athlete’s physical condition] and that could be considered useful to a competitor. It's a big negotiation every time we want to put any type of data in the feed.”

Mapping mountains and explaining incline

The routes are announced in October for the following year’s tour. APO provides the teams with GPS files and mapping which they input into an app called Velo Viewer.  TNT Sports has just begun using this too as the basis for analysis presented in 3D AR graphics.

“The red sections are very steep uphills, the blues are very steep downhills, and you can select whatever section you want to look at in any detail,” Ferguson explains of the source topology. “You've got maps so that for a Finish Line, teams can look in detail to understand where to position themselves for specific turns. Teams will have all of this displayed in the car and we're now using this on set.

“One of the hardest things to get across is how difficult a climb is. Most people can't really get their head around numbers like 19 kilometres at 7.5 percent. In the UK, in particular, there's absolutely no comparison that we can make. Hardknott Pass is 30 per cent in sections but it's only 4-5k long.”

To mark the 50th anniversary of the Tour’s King of the Mountains competition, the organisers have constructed a route with over 50,000 metres of elevation gain.

Stage 6 on July 10 covers 201.5km from Bayeux to Vire Normandie through the heart of ‘Norman Switzerland,’ a hilly region in northern France known with tight roads and more than 3,500 metres of elevation gain in one day.

Stage 18, Vif to Courchevel Col de la Loze on July 24 is 171km long has a 5,000m elevation gain, with summits culminating on top of the 2,304-metre Col de la Loze. It’s the hardest stage in the 2025 Tour de France.

“That's horrendous. We can display that animated out of the floor in front of our studio position so our presenters, when they step towards it, will almost be dwarfed by its scale. It looks much more dramatic than saying its 20K at 6.4 per cent.”

A returning graphic is the inclinometer, a life size Subbuteo figure on a bike, demonstrates the angle of the rider on the climb, which at one point on the route inclines to 20 per cent.

“It's horribly steep, but saying that it’s 20 per cent for these 200 metres is nowhere near as good as showing it. It's a serious point. That could be the point where a rider breaks. At this point they’ve already got three weeks of fatigue in their legs. It might only take 200 metres at this severity to lose the race. It gives us an emotive but simple way to talk about it."
