Drones: Tech For Every Occasion

Broadcast: Drones Directory 2015

UAV selection often comes down to weight and keeping below the 7kg limit of standard CAA flying regulations. Doing so at the budget end requires use of lightweight fixed lens cameras like GoPro Hero, the Blackmagic Pocket Cinema Camera or gimbals with built-in cameras such as the DJI Zenmuse X3.

Currently available choices won't provide the data rates suitable for more than limited broadcast though DJI's X5, the latest version of its stabilisation mechanism includes a Micro Four Thirds 4K camera designed to achieve better quality. One to watch is the kickstarter-funded Z Camera which aims to develop the world's smallest UHD imager with interchangeable lenses.

While the just released Solo drone from 3D Robotics provides an alternative for GoPro users, the most popular off-the-shelf rigs at this end of the market are DJI Phantom 3 and Inspire. While a Phantom can be flown by a single person and is therefore cheaper, the Inspire offers dual operator control - of the aircraft and of the separate pan, roll, tilt motor of the gimbal - providing for smoother and more accurate dynamic camera movement.

The next step-up in camera quality are bulkier DSLRs like the Panasonic GH4, Canon 5D Mark III and the mirrorless Sony a7S II. There are customized gimbals for some of these models, such as the DJI Zenmuse Z15-5D for the 5D series, which efficiently minimise weight. Still in the sub-7kg category, the DJI S900 is routinely used to carry Panasonic GH4s on a Zenmuse with a 6-12mm Olympus lens.

Freefly Systems' Alta will permit mounting of such cameras underneath or on top to obtain fresh angles, using its MoVI stabilizers. It has a folding frame for easy transport and therefore useful for factual. The DJI S1000 and DJI S900 also fold-down and can be a better solution for a hostile environment, or if you’re travelling abroad and don’t need a full broadcast-spec camera.

For cameras more exacting of a broadcast spec, including the Canon C300, Sony FS7 and F55, RED Epic/Weapon or ARRI Mini, you will need platforms capable of carrying heavier payloads. Even the GH4 married with a different lens may push total weight over the 7kg mark. With a cinema package you will need control over the camera's exposure with a lens control system which adds to the weight. A plus in moving up the weight scale is that larger battery packs can be carried, upping flight time from an average 15 minutes to 30 minutes.

Airframe options here include the DJI S1000 octocopter, Intuitive Aerial Aerigon hexacopter and Freefly Cinestar 8 HL with Movi 15 gimbal; the additional rotors generating greater lift.

Productions with a more specific requirement, such as significant payload capacity or ultra-precise movement, might try custom-built airframes. These will be more expensive than out-of-the-box systems but the makers are said to provide better customer service. Gloucester's Vulcan UAV, for example, will design and build drones from the ground-up.

If live broadcast is required then links from Teradex or Paralinx, used in conventional ground systems, are an option. Amimon, developers of the core technology behind those units, has launched Connex HD specifically for the aerial market and capable of delivering an HD link over 1km.

For unique mobile lighting there's the LED Light Heli system from Digital Sputnik. A drone is able to carry the system, controllable by Wi-Fi, which has an output equivalent of 1.5kW HMI, perhaps lighting night time action being filmed from a second drone.


Autofollow tracking systems require no pilot or camera-op and can be controlled from smartphone apps. Intended for the extreme sports market, care should be taken if used professionally since no vendor, let alone those with pilotless technologies, have developed failsafe collision avoidance systems.

P28 British Cinematographer Nov 2015


A belief in the power of LED as the future of professional lighting technology inspired Danish duo Peter Plesner and Thomas Brockmann to start up Brother, Brother & Sons (BB&S) in 1999, although it took a decade for their vision to be vindicated.

http://www.imago.org/images/pdfs/BRITISH_CINEMATOGRAPHER/BC%2072.compressed.pdf
LEDs were not at all useable in 1999,” says co-founder Plesner. “We believed that LED would be the big thing for the future but it took a while for the quality to reach a point that we could use them.”
Between 1999 and 2007 the company concentrated on developing motorised or manually operated lighting fixtures or engines for lighting manufacturers. The Warp for ADB-TTV was the first product developed. In 2007 BB&S started its first LED product development with the Evenled (later acquired by Martin Audio), followed by LED-based retro-fits for De Sisti, Robert Juliat and ARRI. The Aledin-AR backend light engine, for example, mounts into ARRI ST 1 Fresnel. It also created a LED light engine for the De Sisti Leonardo Fresnel.
Then, in 2011, BB&S began development of a proprietary product portfolio of it own high-end LED lighting products and to transition from a development house into full-scale manufacturing, sales, marketing and distribution.
The first step was for LED technology to reach the same level of output as Tungsten or daylights,” says Plesner. “That has been achieved. We next moved to developing the quality of colour rendition. That goal has also now been attained.”
Its key product is the AREA 48 Soft, introduced in 2012. Instead of LED arrays, the AREA 48 uses remote phosphor, widely viewed as an elegant solution to one of the biggest problems to plague LED lighting technology; how to produce a wide spectrum white light and achieve a high colour rendering index for accurate colour rendition.
By swapping phosphor-coated panels of the AREA 48, light can quickly change from daylight to Tungsten or other colour temperatures. The system’s colour rendering accuracy is over 95 TLCI (Television Lighting Consistency Index), and the source is comparable to a traditional 1K soft light.
Every test made to date clearly shows the AREA 48 will reproduce the exact same skin tones as daylight or Tungsten even when shooting in RAW,” says Plesner. “There is absolutely no colour shift when dimming, no green or magenta mess up and therefore less work in post even when used in conjunction with traditional light sources.”
Recently debuted accessories include a new reflector, an octagonal soft box and frames for ganging two or four AREA 48s together for a more powerful soft light. Also new is the AREA 48 Soft Studio, made especially for front of house applications, TV or motion capture studios where extremely smooth dimming in the last 5% is needed.
At face value LED fixtures can be more expensive than Tungsten, a reason attributed to the greater R&D cost to make an LED fixture than an old-fashioned Fresnel. “However, you also have to factor-in that for traditional fixtures you need thick cabling and dimmers to be installed in studios, whereas with LED you just need an inexpensive DMX cable so the cost of running LED is less,” he argues.
AREA 48s are used on a wide variety of TV and feature productions including the Eurovision Song Contest, in their hundreds on Pirates Of The Caribbean: Dead Men Tell No Tales (2017 with cinematography by Paul Cameron ASC), and 2016 Lionsgate fantasy Gods Of Egypt, whose DP is Peter Menzies Jr. The gaffer on both features is Shaun Conway, of Conway Film Lighting with AREA 48s supplied by Barbizon of Australia.
The second innovative product using remote phosphor is the Pipeline. These are modular, cylindrical fixtures built with a diameter of less than an inch to be installed in banks of up to four pipes, or deployed in a single reflector for modelling faces and illuminating backgrounds.
The Pipeline is very slim, allowing gaffers to create a lot of different reflector forms,” he says. “It also matches the TLCI of AREA 48 which means it will match Tungsten or daylight fixtures so you can confidently use existing or older kit alongside the new which is not the case with all LED fixtures.”
The product has been packaged into Pipeline Reporter to address the challenges of travelling correspondents who often deliver their reports via Skype or Microsoft Messenger from a webcam on a desktop. BB&S’ founders share experience in designing lighting for TV, theatre and feature film.
Plesner himself spent the first 25 years of his career as a lighting designer for opera. In a small country like Denmark lighting for different disciplines was par for the course, but we see this merger happening in larger markets too, especially as film and TV cameras get closer together in terms of application.”
The company is based 2km outside of Copenhagen towards the airport in an old industrial area that is undergoing urban renewal. There, the R&D team comprises experts in optical physics, electronics, mechanical design and software processing. All assembly is housed there too with distribution over a worldwide network of 37 dealers.
Plesner is in no doubt that LED will replace virtually all Tungsten and daylight fixtures. “If you go to Singapore and mention Tungsten they don’t know what you mean,” he says. “South East Asia has already moved to LED. It is just the more conservative markets of Europe and the US, which are slower to transition. The introduction of new technologies is bound to retire all the older, heavy, extremely overpriced and power- consuming fixtures.”
Whether LED will supplant 12k and 18k HMIs is another matter. “There are occasions when you do need a large point source, to make strong shadows coming through a window for example. But for smaller luminaries it makes no sense to use that amount of power and heat when there are far more economical technologies available.”
The next step for the company is to find new ways of creating lighting instruments that fit the more extreme resolution and sensitivity of the most recent digital cinema cameras. Sony’s A7S II full-frame mirrorless camera boasts an ISO range from 50 to 409600 and the Canon ME20F-SH claims an ISO in excess of 4 million.
The picture quality from imaging systems will rise significantly and therefore the quality and usability of the light source must follow,” he says. “Lighting will continue to play a huge part in creating skin tone granularity and crisp images.”
BB&S collaborates in scientific research with the Danish Technical University (DTU) Photonics Unit in order to prepare for future leaps in lighting technology.
We hear a lot of feedback from DPs about being asked to light for two locations in a day,” says Plesner. “They have to be able to run everything off a battery, there is no time for cabling. There is a demand for greater speed on-set and for more efficient workflows. All we can do is listen to users and try to give them what they need.”


12 Tips For Using UAVS



Vet suppliers: Common sense, maybe, but with around 1000 CAA-licensed UAV services in a fledging industry which do you trust to undertake your project? Showreels should be a guide only, word of mouth often a better bet. One differentiator is to ask for certification to fly 20kg payloads. This should mean the outfit will have wider experience with dual pilot and gimbal control.

Two better than one: You can get great results with a single person flying the system, but the more dynamic moves happen with a dedicated gimbal operator moving the camera in accordance to a DP's instruction.

Pick the team, not the hardware: Sure, rigs and cameras are important but not as important as the crew you'll be working with. Competent UAV teams will understand professional broadcast, meaning an appreciation of the workflow, the language of pans and tracking shots, and the format you need to walk away with.

Understand the law: Each country has a different approach, and regulations are playing catch-up with the explosive trend. Key UK parameters include staying more than 500 meters away from people and buildings and to a maximum altitude of 400 ft.

Look for CAOSC: Staying under the 7kg limit was mandatory for all UAVs in heavily populated areas often to the detriment of onboard acquisition quality. Operators can now obtain a year-long CAA regulated Congested Areas Operating Safety Case to fly rigs up to 20kg anywhere, increasing your options and speeding up planning for jobs.

Speed: How fast do you want to fly/track? Drones are good for about 35 mph. Any faster and you will probably need a conventional helicopter.

Camera package: Check that the camera package proposed suits your purpose and does not require great amounts of post stabilisation. Note that most drones cannot fly a larger cinema sensor camera and zoom lens.

Plan ahead: Shooting views of a presenter walking up a hill is straightforward but only if your UAV operator has worked the logistics of access and securing permissions. While staying below the magic 7kg can speed the process, note that some air traffic permissions can take up to 10 days to secure.

Force 10: Weather can play havoc with any location shoot but excessive wind will ground flights, so have a contingency plan.


Storyboard it: A drama director may have a specific aerial vision in mind. Bring the UAV team in at pre-production to fully understand the requirements which will have a baring on hardware choices, safety concerns for stunts and complex camera moves.

Do you need one? When a jib, balloon, helicopter, kite or Russian Arm is best? The latter is a remotely operated vehicle-mounted gyro-stabilized crane. If you need to track a car at 70 mph and keep the camera consistently within 6ft of the bonnet, you'll want this.

Think space: The bigger the open space, the more you will get out of the drone. Large controlled areas mean you can place the camera wherever you want. Drones unlock aerial shots in confined spaces like caves, tunnels, hangars. Beware the noise of the rotors though.
Don’t fly uninsured: If you engage an operator to fly something with mass and moving parts, you should think about what happens if there's an accident. An insurer will require CAA permission to fly.

For your budget: Rates vary between £800 to £2000 per day with the more experienced pilots commanding a better rate. The average fee is around £1000 and usually includes pre-planning, site recces and permissions as well as the camera and rig.

P28 Nov 2015



A belief in the power of LED as the future of professional lighting technology inspired Danish duo Peter Plesner and Thomas Brockmann to start up Brother, Brother & Sons (BB&S) in 1999, although it took a decade for their vision to be vindicated.

Go Compare-style Portal For Post Production Possible, Say DPP

BroadcastBridge
Trading and booking post production resources could be streamlined by an online comparison service, similar to how many of us search for car insurance, according to British industry alliance Digital Production Partnership (DPP). It is conducting research into the future of production and has already sized up implications of digital tools for content creation, programme distribution and the business model that has cemented post house and producer relationships for years.
“We feel we are entering the biggest moment of potential change in how programmes are made for a decade,” explained Mark Harrison, Managing Director, DPP. “If you are starting out now as a content maker you would not have grown up in the established TV culture of linear broadcast. Consequently, you would take a very different approach to how to make content. You would use web-based editing tools and cloud storage. You would likely shape your finished output using a range of non-geo-specific services. And of course you might be publishing direct to the web.”
Perhaps most fundamentally, the trading relationship between facilities and content producers might change. 
“You would likely shop around for these services using the web rather than running or ringing around Soho for the best deal,” Harrison suggested. “I can imagine a time when even makers of high-profile, long form programming might seek to identify – and buy – all their creative services for dubbing, grading and finishing through a Go Compare-style web portal. The question is how far away this is.”
Harrison added that such a scenario did not mean that craft talent would go unvalued. “On the contrary, craft talent will remain extremely important at the higher end. It is just whether the buying model, and the way content is delivered, might start to move online.”
These ideas will be detailed by the DPP in a far-reaching report it is announcing the start of today as part the organisation's 2016 road map.
“We're looking at the extent to which digital tools are now becoming appropriate to the broadcast domain and how it will fundamentally shift the way we position product,” he said. “It is about the opportunities that now exist to use internet-based production tools but also the opportunity to create audio visual content for suppliers and distributors other than mainstream broadcasters. Market distribution is much more diverse now and tools and technologies are beginning to much more diverse.”
The DPP won plaudits for its remarkable smooth oversight of a file-based delivery standard into UK broadcasters which has been in train for over a year. 
Other aspects of its 2016 road map includes a version of the AS-11 delivery specification for North American broadcasters and collaboration with the EBU on a common international programme mastering format.
“There is a lot of support for an international exchange of content and with the EBU we can try and ensure this comes about more quickly,” he said. 
Earlier this year the DPP became a limited company and introduced a fee structure for members, which was somewhat controversial among post production facilities which felt that they had contributed enough investment in new equipment, plus feedback to the DPP, to get file-based delivery up and running.
As a result, the DPP dropped a proposal to introduce a Kitemark (certification) endorsement for post firms in March.
“We've always prided ourselves about the benefits of our work to the whole industry and now we have members we can interact with directly,” Harrison said. “The quality of insight and engagement they give us is second to none, and so it feels as if giving us [their participation] gives us that extra relevance.”
He continued, “By being part of the DPP you get to shape [the future]. The quality of insight members are getting into the industry is enormous. They get that insight very early. 
“We are the only organisation that can bring all the parts of the supply chain into a room together at the same time to share insight into how to integrate change or create market opportunities that nobody else can bring. That's the thing our members tell us is important to them.”
Since introducing fees, the DPP has collected 48 paying members including UK broadcasters (including BBC, ITV. BT Sport, Sky, Channel 4 and Channel 5 plus nations broadcasters STV, TG4 and UTV with Fox); vendors including Sony, SAM, Vizrt, Tektronix, Ericsson, Suitcase TV and Fujitsu; service providers Deluxe, Sohonet, Aspera, Screenocean, Dock10 and Arqiva and a handful of post production facilities including Envy, Deluxe brand Encore; Gorilla TV and The Farm.
Annual fees for a UK broadcaster are £25,000; for service companies or kit vendors up to £4000 depending on turnover; and up to £4000 for facilities depending on turnover.

Eye Spy: John Mathieson on Man from U.N.C.L.E


British Cinematographer

Guy Ritchie's new spy-fi action comedy pairs a duo of special agents on opposite sides of thc cold war. In roles popularised in the 1960s MGM V series starring Robert Vaughn and David Mccallum. The characters, like the cars featured in the movie are vintage. But the story is new.


For the film, Ritchie and co-writer and producer, Lionel Wigram, conceived the idea of an ‘origins’ story that would reveal how CIA operative Napoleon Solo (Henry Cavill) and KGB agent Illya Kuryakin (Armie Hammer) met and arrived at their unlikely collaboration for the mysterious United Network Command for Law and Enforcement (U.N.C.L.E.).
Philippe Rousselot AFC ASC, who had lensed Sherlock Holmes: A Game Of Shadows for Ritchie was assigned to the project but unfortunately had to withdraw at the eleventh hour. So the ball passed to John Mathieson BSC – a more capable substitute you could not imagine.

As far as Mathieson can tell, he got the gig following recommendations from co-producer Max Keene, gaffer Chuck Finch, and camera operator Chris Plevin – all collaborators with Ritchie on Sherlock and each with connections to Mathieson, the two time Oscar nominee (Gladiator, The Phantom Of The Opera), through their work together on films such as 47 Ronin, Robin Hood and Kingdom Of Heaven.
“I kind of got the show by way of a few references and the misfortune of a fellow DP,” explains Mathieson. “It came rather quickly and the technical crew and much of the key decision-making was already in train.”

The timing wasn't ideal for this avowed enthusiast for film. In early 2013, in the wake of the pending closure of Technicolor's processing lab at Pinewood but before Deluxe-owned Company3 joined with iDailies, and long before Disney landed Star Wars in the country, UK film processing was on the verge of collapse. “There wasn't a choice about U.N.C.L.E.'s shooting format, we had to shoot digital,” he says.

Mathieson had shot with REDs and ARRI Alexas previously but doesn't favour one over another, viewing all digital cameras as essentially inferior to negative. “I couldn't really care if I never saw a digital camera ever again,” he says. “With digital you don't have to be a craftsman. You can shoot and add colour and exposure in hindsight rather than sculpt instinctively in stone. But U.N.C.L.E. was not a bad project to do digitally. Digital cameras will give you synthetic primaries, rather than burnt Renaissance painting colour, but then this is a Sixties’ pastiche comic-strip with bright, bold colours. So I thought, 'let's just go with it and not be a Luddite about it’.”
Principal photography began in September 2013 on Alexa XT with some B-roll shot on GoPro Hero (unused in the event). Canon EOS 5Ds proved more useful for stunt sequences, including one which resulted in a car being submerged underwater. “We sank the vehicle and couldn't retrieve the footage until a week later but it was perfectly serviceable,” he says.

Like Ritchie's Sherlock Holmes films and his 1998 feature debut, Lock, Stock And Two Smoking BarrelsThe Man From U.N.C.L.E. inhabits a world of both flash and toughness. The director largely left Mathieson to his own devices, concentrating on working with the actors rather than engaging his cinematographer in animated shot-by-shot conversation or suggesting a definitive look.

“We tried to tip our hat to the period,” says Mathieson. “We shot mainly with Panavision E Series Anamorphic primes and older Technovision spherical lenses, which all had the feeling of the time. They possessed aberrations and a fogging or veiling which helped to set the film back, not as far as the Sixties, but certainly a throwback to the past.”

Other glass included an old Cooke Cine Varotal MKII 25-250mm T3.9 zoom, Cooke Varotal 40-200mm, an Elite zoom 240-1040mm and Cooke Varotal T3 for night work.

The closest filmic references for The Man From U.N.C.L.E. were the early 007 James Bond movies of Dr No (1962) and From Russia With Love (1963), both shot by DP Ted Moore BSC. “A lot of the look of those films was achieved in the styling – of two-tone suits, jet-black waxed hair and skinny ties with girls in polyester dresses and classic cars, but the look was quite colourful too,” observes Mathieson. “The film stock of the time is quite rich and contrasty with strong blacks and deep colours. That's not quite so easy to achieve on digital.”

Some 16mm Bolex negative was shot as a transition between the title sequence, containing scene-setting newsreel of President's Kennedy and Khrushchev during the Cuban missile crisis, “to bring us into the digital world as gently as possible,” he says. “You couldn't really cut directly to the Alexa. It's about bending the format to taste. This the look of the 1960s from a 2015 lens.”

Mathieson's lighting package was generally in keeping with the period, mainly met with Tungsten 5K – 20Ks. “We were not using HMI, Kino or LEDs. The Sixties had a lot of fantastic design conveying an opulence and optimism about how things should be, but the computers in our world flash like car indicators. It's not high-tech. The palate for this film is colourful and warm and we felt Tungsten lamps suited that mood. We'd probably have gone with LEDs and fluorescents if we were shooting a more modern type of film.”

Although some Steadicam was deployed, the period nature of the piece lent itself more to track work. “I think we'd all rather track if we could,” he says. “In some ways it can be much quicker to work on set using tracks. It doesn't take long to run a track around and it means you can stop and interrogate a frame, talk about a shot, redress the set or adjust for lighting as necessary while the camera operator isn't bending their back.”

Being a Warner Bros project, Leavesden was the show's studio home supplemented with a considerable amount of location shooting. The Royal Victoria Docks near London's City Airport was a mock-Mediterranean harbour. An old mill near City Airport and derelict buildings at Chatham Docks provided a backdrop for bombed-out East Berlin. A scene set under Brixton's railway arches was used for “spies coming out of greasy garages exchanging packages, picking up fast cars”, and Greenwich's Maritime Museum doubled as Berlin and the backdrop for a car chase. Various London interiors in keeping with the ‘60’s period were also used. A café was specially-built in Regent's Park.

The mission itself begins in Italy on location in Rome, Naples and Neapolitan islands, including interiors of large municipal buildings of the La Dolce Vita period “with shiny floors, columns and lots of glass. A certain degree of elegance you wouldn't get anywhere else,” Mathieson recalls. “We shot in the Grand Plaza hotel near Rome's Piazza del Popolo which we just shot for what it was – falling down rococo with old-fashioned décor, a wonderful staircase and reception areas.”

The Alexa data was handled by DIT Francesco Luigi Giardiello on-set and on to Technicolor for post, using the Codex workflow, but Mathieson professes to be more interested in getting the images right and controlling the final look than the technical process that happens in between.

“If you give it the right exposure you can achieve a very different feeling within the same lens,” he says. “If you want a hard look or a soft, swimming look with flare you can do so within the iris. Some of the older zooms have had their front elements taking quite a beating which was great to play with.”

He continues: “When you look at the Log or at the RAW image in digital it's horrifying, but you want to make sure the images are as good as graded rushes. When things are in editorial the scenes will move up and downstream and the story arc and time of day will change and, therefore, so will the look. You might then have to soften the lighting to move from a dawn to dusk scene.”

He worked with colourist Paul Ensby over ten days, locking the picture down by summer 2014. “I'm not someone who spends hours in the grade finessing each detail. I view the DI process as a piece of music with shades of fortissimo and mezzoforte and that the more you tinker with the image, the more you risk ruining its rhythm.”

He says, “The way I like to grade is to take the best shot in a particular sequence then grade around that, rather than trying to add in windows which just tends to average everything out. Maybe the end result is rough around the edges, but I'd rather have that than a piece which is bland and boring. I got it to where I wanted it to be. But I would have made it look better on film.”

This from a craftsman who learned his trade on U-Matic and BetaSP before graduating to film. “It's a great shame that there's a generation of kids who have never had a chance to try 16mm. Now everyone graduates to shoot digital. Even if they want to shoot film they are not given the confidence to expose film.

“We're talking about the key craft skill of using one's eye to judge exposure, to really look at the light rather than looking over your shoulder at a monitor with a waveform and vector scope before pressing a record button.”

He adds: “I can't tell the difference between the looks of a lot of the big VFX films. Did any cameraman put their stamp on it or even design it?”

Mathieson is well aware of the irony of currently filming the hefty CGI fantasy Knights Of The Roundtable: King Arthur, also for Ritchie, back at Leavesden.


“There is a place for massive stories told in VFX using a computer, but the sadness is that we've lost a generation unable to make the leap to shooting film,” he says. “I could teach twenty students how to light for greenscreen in just half a day. When I shoot greenscreen my arm is tied behind my back and I just glaze over since my input is redundant. If I sound disillusioned, I'm afraid that's how I feel.”

HDR is the new black

TVB Europe
High Dynamic Range is touted by some as the best thing since the introduction of colour but will all HDR versions of it be equal?

The potential to offer High Dynamic Range (HDR) is considered by many broadcasters and OTT players to as a key value proposition in the move to upgrade viewers from HD. Both Netflix and Amazon Prime are offering UHD HDR remastered videos and shooting original content in the format. For little to no additional bandwidth, viewers can see a difference over normal HD at any viewing distance. There can be few if any manufacturers with a stake in Ultra HD not also offering a means of getting HDR through the chain. As Simon Fell, EBU director of technology and innovation neatly put it: "HDR is the new Black”. 
While the average TV today has a brightness range of around 100 candela per square metre (known as nits), HDR displays could offer 1,000 nits, 1,500 nits or more. That’s still far less bright than some things you might see in real life, but the increased luminosity will still mean a far more realistic picture. The difference is immediately apparent when looking at images of water, or of clouds, for example. 
The introduction of HDR also ramps up the colour. HDTV is based on an 8-bit system, meaning there are up to 256 shades of each colour available (in theory – in practice around 220, for historical technical reasons). But with HDR, a 10-bit system allows an increase in the colour gamut to 1,024 shades of each colour. Combine increased luminosity and richer colour with the greater resolution 4K can provide and HDR could be as important an experience as the introduction of colour was 80 years ago.
“It's hard to believe unless you experience it,” claimed Dominic Glynn, Pixar's senior scientist who guided the HDR finish for Inside Out. “We can show the audience colours they've never seen before.”
But any mainstream TV industry shift towards HDR will be delayed as technical standards are agreed. “How you create that HDR data chain is a question that needs a lot more attention,” said Sean McCarthy, engineering fellow at Arris. “It’s not as interesting as the pretty colours and stuff, but it is important.” 
“HDR is the area with the least agreement across the board for a single standard,” notes Rowan de Pomerai, senior technical manager, Digital Production Partnership which wants to design a single UHD HDR specification for programme delivery.
SMPTE will publish a Study Group report on the current state of the HDR ecosystem for content mastering and broadcast shortly. It has already published two HDR standards related to content mastering: ST-2084, for the Electrical Optical Transfer Function (EOTF); and ST-2086, to define static metadata. SMPTE is now working on a standard for dynamic metadata needed to support SDR and HDR content at the same time. 
Dolby helped deliver SMPTE 2984 implemented in its own Dolby Vision system – this SMPE standard has been adopted in the Blu Ray Disc Association. Content owners including most of the studios are starting to remaster older content for HDR-compatible UHD Blu-Ray. 
However broadcasters BBC and NHK have expressed concerns that this standard is not ideal for the workflow of live TV where a single broadcast version needs to deliver acceptable quality on both HDR and standard dynamic range (SDR) displays, minimising additional bandwidth. This is a different challenge to on-demand content or packaged media, where different versions can be created to optimise the quality for both SDR and HDR, and selected for playback appropriately. 
So NHK and BBC have created the Hybrid Log-Gamma HDR solution to try and solve this issue. It intends to ensure that an UHD HDR signal can be displayed not only by HDR-enabled devices but in the vast majority of household sets with the SDR range of HD. It is one of a number of options being considered by the ITU for standardisation, but even then it then needs to be implemented into TV sets. 
Which brings us around to the consumer messaging: TVs are already being marketed as supporting HDR, but which standards are they supporting? How ‘High’ is the dynamic range, with brightness levels of displays varying from 400 NITs to over 1,000 NITs and giving dramatically different experiences for the viewer. 
“Currently, the clearest proposition is the BDA, with Ultra HD Blu-rays reportedly launching before the end of the year,” says DTG chief technology officer Simon Gauntlett. “The HDMI specification was updated to 2.0a, to deliver the metadata to the displays to enable SMPTE 2084 presentation. This suggests that if the display supports HDMI 2.0a it should decode HDR content correctly . However the message to consumers is far from clear.” 
Peter White, CEO and co-founder, Rethink Technology Research, agrees: “HDR is being seen by many TV manufacturers as something that they will introduce after 4K. That’s the wrong approach, but the TV manufacturers hold a lot of sway. In the US, manufacturers are selling ‘4K’ devices that are not UHD. The fight to differentiate among those players is pushing ‘4K’ rather than UHD, in the same way that they tried to push 3D when no-one was ready for it.” 
The UHD Alliance which includes members of the consumer electronics community and Netflix is also trying to specify UHD, which will include HDR requirements. All eyes will be on the CES show in Las Vegas in January where the next crucial stage of the UHD HDR debate will be played out. 
Live HDR 
For live broadcasting the issue is more complex. The main outside broadcasters including Visions, Telegenic and Arena, are testing live HDR (UHD and HD chains) for clients including BT Sports. Delia Bushell, managing director at BT TV said at IBC that the company is looking to add HDR capabilities to its Ultra HD 4K channel within two years.
How might live HDR broadcasting be handled? Technicolor has a new server-based version of its Intelligent Tone Management software that scales standard dynamic range source material (such as 4K 60p) for HDR use. The aim is to allow sports or live event productions to continue use current cameras and infrastructure at a venue with the upscaling occurring on the final output mix.
Importantly, the upscaled signal is routed through an Elemental encoder which spits out a single stream which can be received in HDR and SDR which for a broadcaster reaching the mass of households with plane old SDR screens is a must.
“You can't justify the cost of running two infrastructures so the distribution system needs to be combined,” says Mark Turner VP, Business Development & Relationships. “The cheapest way of implementing HDR live is for the mix to happen as normal with the final mix upscaled. OB engineers can adjust the settings in realtime or apply different HDR settings to different sports.”
Dolby offers an alternate route to HDR. It has worked with Grass Valley to introduce a process for individual camera feeds. Grass Valley has a XDR software-upgrade option for all LDX 86 Series cameras working in single-speed formats (HD/3G/4K). This is claimed to deliver 15 F-stops of sensitivity to the home with a suitably equipped HDR set. At IBC the feed was encoded along with the HDR information by a Muse Live encoder in from Envivio (now an Ericsson company). A licence upgrade from Grass Valley is required to unlock it on all LDX series, plus you need a monitor to view it on – and Dolby has those.
Sony pledged its commitment to incorporate HDR capabilities into more of its production equipment. It has trialled 4K HDR capture with Dorna Sports using HDC-4300’s at the 2015 British Grand Prix MotoGP.
Michael Harrit, Marketing Director, Sony Europe, said, “We have built HDR into leading production tools to create an HDR end to end production workflow from acquisition to delivery to the living room.”
RED Digital Cinema also has a live HDR output solution allowing users to simultaneously monitor both the standard dynamic range and HDR images of the same shot on-set, in real-time. That will allow users to see more of what the sensors on their cameras are capturing – from the deep shadows to bright highlights. Like Dolby, the RED solution meets the SMPTE 2084 standard.

Creatively, what can HDR do?
There are also some obvious ways in which HDR could enhance specific types of programming like sports: it means you can actually see a flying golf ball against the sky; or watch a football match in a stadium half in and half out of bright sunlight without experiencing that clunky moment when the camera has to jump through five or six stops as the play moves in or out of light or shade. 
Pixar's Rick Sayre says that on Tomorrowland, on which he was Digital Imaging Consultant, the HDR “revealed a gleam in the eyes of the actors which it has not been possible to show before.”
“The eye tends to be drawn to the highlights which can pull a viewer out of the story,” says cinematographer Steven Poster. “We may see some gimmicky HDR that has nothing to do with storytelling. Just because we can now see through a brightly lit window exterior doesn't mean that we should.”
“As time goes on, filmmakers will take advantage of the expanded colour space offered by the use of laser light source technology to bring colours and contrast never seen before on a cinema screen,” says Stuart Bowling, Director, Content and Creative Relations at Dolby.
“Animation is an amazing way to apply wider colour gamut to audiences,” he adds, highlighting a scene in Inside Out which exploited Dolby Vision’s wider colour gamut capabilities. This is when Joy and Sadness enter the Subconscious and the production design called for the look of a black-light room— glowing, colourful, and highly saturated.
