AI helps InterDigital reach beyond VVC in race to develop next-gen codec
Streaming Media
Candidates for H.267 already significantly outperform
VVC as the hunt for a new video compression standard gets underway
article here
The starting gun has been fired on development of a new
video codec beyond VVC with gains of at least 20% up to 50% claimed by R&D
lab InterDigital.
The target for H.267 is to deliver improved compression
efficiency, reduced encoding complexity and
enhanced functionalities such as scalability and resilience to packet loss.
“It's a real big challenge and a great opportunity to
develop new ideas, patents, and algorithms,” said Edouard Francois, Senior
Director 2D Codecs Lead at InterDigital. “In particular, we are exploring how
AI can be used in synergy with traditional video compression methodologies.”
Headquartered in Wilmington, DE and holder of more than
33000 worldwide patents and applications across wireless, Wi-Fi, 5G/6G and
video, InterDigital is one of the world’s largest pure R&D and licensing
companies.
StreamingMedia was given a tour of its video lab in
Rennes, France, InterDigital where scientists said they were exploring
combinations of AI and traditional compression methodologies to compete for
patents that could be locked into H.267 when the standard is published in 2029.
There has been reluctance among some companies including
Amazon to formally kickstart a new video compression project which could mean
rip and replace of encoders in their existing ecosystem. In addition, many Big
Tech and streamers are committed to working with rival codec AV1 from AOMedia.
“People were cautious,” says Francois. “That’s why ITU and
ISO convened a workshop to ascertain market demand. The key question was were we
able to compress video with a significantly better efficiency than VVC?”
At that workshop the Joint Video Experts Team (JVET) which
reports to ITU-T VCEG and ISO/IEC MPEG issued a call for evidence. Samsung and
Amazon were among attendees.
“The goal was to show the state of the art of video
compression where anybody can come with crazy ideas,” says Lionel Oisel, Head
of Video Labs and General Manager, InterDigital France.
Nokia, Ericsson, Fraunhofer HHI and InterDigital responded
to the call and presented their results at a JVET meeting in Geneva earlier
this month.
“That was very important because there was a clear
expression of interest in the need for a new video codec,” says Francois.
“Further increasing compression efficiency, because reducing the bit rate is
always good but with an encoder which is easily configurable and where the
complexity on the encoder side is at least maintained to a reasonable level.
“Fraunhofer HHI demonstrated success. They had optimised a
lot of their software, removed some constraints of VVC and added a few tools and
were able to achieve a 20% bit reduction gain running at the same encoding speed
of VCC.”
InterDigital made dual responses. One, called Enhanced Compression
Model (ECM), was based on conventional codec schemes and the other was a hybrid
of VVC overlaid with AI tools termed Neural Network Video Coding (NMVC).
The former was made principally in partnership with Qualcomm
which was actively involved in ECM development and the latter was made in
tandem with Huawei.
InterDigital had begun work on ECM in 2021, a year after VVC
was finalized. Designed purely for research and without taking account of
encoder complexity, by the end of 2024 ECM had reached version 18 and was
demonstrating a coding gain of 28% over VVC.
In purely visual tests the company claims it can achieve 50%
gains for some sequences.
“Overall more than two thirds of the sequences were gaining
30%,” says Francois. “The evidence shows that you can outperform VVC with an
encoder that has reasonable complexity. NMVC consists of VVC plus two to three
ML/AI tools which could increase efficiency further.”
When new codecs are developed there is traditionally a
trade-off between reduction in bitrate and increased encoder complexity. If
saving bitrate was the only goal then you could keep introducing more complex
tools and algorithms, however this makes the encoder much more complex to
implement. Reducing or at very least maintaining complexity levels was a key
ask by the market.
At the October CfE meeting it was agreed that there was
concrete evidence that with existing tools a new encoding method could
significantly improve on VVC without increasing complexity. JVET gave the
go-ahead for a call for proposals.
Competing participants in this next stage, including
InterDigital, will now work until January 2027 before presenting results back
to ISO/ITU for assessment. Finalisation of the new standard is expected by end
of 2029.
“We only used publicly available technologies and publicly
disclosed algorithms to answer the CfE but we have internal technologies that were
not disclosed and which already in our lab tests do better than the CfE
response that we submitted,” Francois explains.
“Now, we switch to hidden mode and we develop tools and
technologies internally. Many other
companies will do this too over the next 18 months. Our research is focused on
keeping the complexity low. We cannot make the complexity explode.”
Key research aspects include optimising the trade-off
between bitrate and visual fidelity, developing fast encoding methods suitable
for constrained devices, and advancing performance in emerging use cases like
HDR, 8K, gaming, and user-generated content.
The standardisation phase will start after January 2027 and
will be a collaborative effort led by JVET.
“Everybody works on their own or with some additional
companies trying to bring the best potential solution that will be evaluated in
January 2027 but the one that will win won’t become the standard,” says Oisel.
“Instead it will likely be used as a baseline for further development from 2027
to 2029.”
He adds, “This standardisation period will determine which
tools are adopted (therefore licensable). To do that you have to prove that it
delivers huge gain and also that you don't have high complexity. The issue with
AI tools is that they put the complexity on the decoder side which is something
that chip makers like Broadcom will fight against because they don’t want to
add complexity to their hardware. If you come with a tool with huge gain but also
huge complexity then this won’t be selected.”
VVC state of adoption
VVC itself has been slow to rollout so news of a potentially
superior codec launching in less than four years may stagnate adoption
completely.
“Everybody's waiting for a trigger,” says Oisel. “The
trigger could come from the content provider but to deploy that they need hardware,
they need encoding solutions, and also decoding solutions on the devices.
“There are a large number of TVs that potentially can decode
VVC, whether enabled or not, and a couple of mobile phone manufacturers have
developed VVC decoders. There are encoder solutions too but not necessarily fully
optimal yet so this means that you don't reach the full bitrate gain of VVC. On
the content provider side VVC is adopted as standard for next generation TV in
Brazil. Content providers who wants to stream TV3.0 in Brazil will have to
implement VVC. Encoder manufacturers will have to comply with the requirements
of their customer (TV Globo) and TV manufacturers will also need to be TV3.0 compliant.”
ATSC3.0 which is rolled out to more than 75% of US markets
references VVC as a codec; as does DVB in Europe but people are still waiting
for a trigger.
“It could come from Brazil but the main market right now for
VCC is China. Tencent is using VVC quite a lot where one use case for VVC is to
better manage a huge number of UGC social videos. VVC could be a very good target
for them to reduce the file size because compared to HEVC you have a reduction
between 45%- 50%. Usually it is the US that leads the way but in this case it
could be China that leads o, which is pretty unusual.”
The reference codecs for mobile via the 3GPP are AVC [H.264] and HEVC [H.265]
and the battle to go to the next generation has not yet started. The
competition is likely between AV1 (AOMedia) and VVC (MPEG).
“AOM are to release AV2 by end of this year and it also
seems to be hugely complex on the decoder side,” says Oisel. “Will they be able
to simplify it? Usually, MPEG are in advance compared to AOM. AV2 is using a
lot of tools that were developed for VVC. So there are two parallel tracks, but
the underlying technology between MPEG and AOM standards are, to date, not much
different.”

BTS It Was Just An Accident
IBC
The Cannes Palme d’Or-winning critique of Iran’s police
state was made in secret as an act of defiance. IBC365 sits down with the
film’s Editor Amir Etminan to learn more about the fearless filmmakers’
process.
article here
Criticising the Iranian state in Iran risks intimidation,
imprisonment, or worse, but filmmakers continue to defy censorship. The latest
to achieve recognition is the Palme d'Or-winning drama It Was Just an
Accident.
“Just because this film is about not being able to speak or
work freely in Iran today doesn’t mean we should stop attempting to work or
speak freely,” says Amir Etminan, the 42-year-old Iranian who edited the
feature for Director Jafar Panahi. “Making this type of film in Iran actually
fights against those issues.”
Panahi has been making politically charged films since 2000,
when his third feature, The Circle, was openly critical of the
treatment of women under the Islamist regime. His films, including The
White Balloon (1995), Offside (2006), and No
Bears (2022), consistently win awards. Yet, he has been imprisoned,
banned from travel, and placed under house arrest for most of the past
decade.
The tragi-comedy It Was Just An Accident is
judged to be his most overtly anti-government tale yet. At its heart, the story
presents a moral dilemma: what would you do if you found your former jailer,
and how could you be sure it was them anyway?
Co-financed by French company Les Films Pelleas, the film is
France’s submission for Best International Feature at the 2026 Oscars and was
made under the noses of Iranian officials.
“Unfortunately, in Iran, especially for independent cinema,
we are used to making films secretly,” comments Etminan, who previously
cut No Bears. “We’ve normalised it. Mr Panahi is a very
popular and well-known person in Iran, so we already had this fear and stress
that there would be problems.”
Pulling it off
First, the team obtained fake permission documentation to
make a short film under another crew member’s name. The cast and crew were kept
to a minimum of just 20 people, with several scenes taking place inside a van
to disguise their activity. Cinematographer Amin Jafari shot it all using RED
Komodo, a small cine camera that produces significantly larger files than a
cell phone. Etminan was on set every single day, acting as a digital imaging
technician (DIT) and an editor.
“Every day I would take the memory cards home, make a
copy of them, and convert the files to proxies before giving the cards back to
Panahi to hide,” he says.
Etminan used a modest 2020 MacBook Air with 8GB RAM and
128GB storage to edit the full film entirely offline. He often worked 18 hours
a day with no editing assistant to create the proxy files from the RED
footage.
“Because the situation was very risky and secret, I only had
a small laptop and a tiny SSD so as not to draw attention.”
Nonetheless, on the 26th and penultimate day
of shooting, Iranian security police came to visit the team. Luckily, the RED
Komodo was already mounted on a car and being driven away from the set with
Director Panahi and the actors. However, Etminan and several others were caught,
and the laptop containing the full, edited film was found in the back of
another vehicle.
“The police opened the back of the truck and grabbed the
backpack, which had the laptop inside. They started to question us and wanted
us to stop shooting.”
Next to the bag was a pair of cameras that were props for
the character of a wedding photographer in the film. Etminan made exaggerated
efforts to protect the cameras in a bid to divert police attention away from
the laptop.
“The police thought these cameras were the main cameras we
were shooting the film with. They asked me to open the cameras and tell them
what information was on them. I said I didn’t know and that the batteries were
not working, which, fortunately, they were not. The police demanded the memory
card from the camera, which I gave them, so they went away satisfied that
they’d taken something from the set that they thought was the main card of the
film.” No arrests were made. “They came with 20 people and couldn’t find a
single frame.”
A few days later, with the offline edit complete, Etminan
transferred the finished cut to an 8TB SSD card in Tehran and handed it to
someone “completely unrelated to cinema” who then transferred the files over
the internet to France.
In France, the edit decision list (EDL) was conformed to the
raw footage with VFX and colour grading applied. Etminan supervised all of this
via a video call from Tehran.
DoP Jafari kept the number of takes to a minimum to reduce
the risk of discovery and to avoid having to handle and secrete large volumes
of data.
“One reason I went to the set each day was to calculate the
length of every shot,” Etminan elucidates. “I had to tell them whether the shot
we were filming fitted with the shot from before and afterwards. We would
calculate that on set for every scene across the whole film using notes that
were all in my head.”
He adds: “Mr Panahi was so accurate that after the rough
cut, we didn't have more than 10 minutes of unused footage leftover.”
Flip the script
The drama itself deals with weighty moral issues about
justice, torture, and forgiveness, but set in deliberately absurd scenarios,
which would not be out of place in a Coen Brothers’ fiction.
Etminan explains that such “bitter comedy” is a coping
mechanism.
“Real life is a combination of comedy and tragedy,” he says.
“In the worst situations and the most bitter part of our lives, we retain our
humour. That kind of saves us and helps us survive.”
Much of the dialogue in the film comes directly from
political prisoners’ experiences in Iran.
“Comedy also helps the storytelling. Psychologically, using
comedic moments and small jokes helps us to avoid the complete darkness of such
a harsh reality.”
Similarly, the tale begins by evoking the audience’s
sympathy for a father who accidentally hits a dog while driving his family
home. This incident means their car needs an emergency repair at a nearby
garage, where we are introduced to a suspicious mechanic, Vahid. From this
point, the roles of victim and villain reverse.
According to Etminan, this is achieved through the
writer-director’s approach to story. “In Panahir’s films, the camera won't move
before the characters or before the characters’ actions,” Etminan explicates.
“Instead, the character moves the camera from one spot to another.”
In the first few minutes of the film, Eghbal is the main
character, and the audience gets to know his family. The camera is motivated by
him. Then, Panahir puts the focus on the character of Vahid, a mechanic. Vahid
then becomes the one who motivates the camera to move from one spot to
another.
“Even when all our characters are inside the car, we do not
move the camera outside the car because Vahid has not moved outside the car.
These shifts in perspective between protagonist and antagonist are the classic
forms of storytelling, but in the independent cinema of Iran, we prefer not to
use those classic forms.”
Facing the future
The risks of making such films are borne by everyone
involved, Etminan included. In 2022, after making the feature No End,
directed by Nader Saeivar about the Iranian secret police, the editor was
forced to flee the country to live in Turkey.
Several times he has been interrogated by the police, but
says these interviews weren’t “harsh”.
“The situation for students and young people in Iran is much
worse. In general, the behaviour of the police in Iran towards people working
in cinema is a bit more polite, because they know it won’t look good for them
when news of their [detainment or suppression] is broadcast
internationally.”
After Panahi was arrested and sentenced to six years in 2022
for ‘propaganda against the regime’ (for expressing solidarity with fellow
Iranian filmmakers Mohammad Rasoulof and Mustafa Al-Ahmad), filmmakers at the
Venice Film Festival and around the world voiced their own support.
Awarding It Was Just An Accident with the
Palme d’Or has been seen as the international film community’s continued
support for artists’ work against state oppression everywhere.
“[Panahi’s] persecution has caused global backlash. He’s
become a thorn in their side,” Etminan says. “Personally, I still travel to
Iran whenever I want. I go there. I come back again. Honestly, we’re not afraid
of repression or prison. After [experiencing it], you get used to it and you
stop caring.
“What I learned from Mr Panahi is that this is our country.
If one day someone needs to leave, it's not us, it's them. It's the regime.”

Mystery, Beauty and Threat: The Endangered World of the Pangolin Revealed
interview and copy written for RED
article here
Pangolin: Kulu’s Journey, now streaming on Netflix, was recently honored with the 2025 Jackson Wild Media Award for Conservation Long-Form for its powerful storytelling and impact. The film’s intimate cinematography and urgent conservation message immerse viewers in the mysterious and captivating world of pangolins. The small, scaly mammals found in Asia and Africa may look unassuming, but they’re among the most poached and trafficked animals on the planet. Academy Award–winning director Pippa Ehrlich tells the story of one pangolin rescued from illegal trade, as the film follows wildlife photographer and cinematographer Gareth Thomas on his mission to rehabilitate the vulnerable animal and prepare it for a life of freedom in the wild.
Back in 2022, Thomas was a conservation volunteer and took part in a sting operation that rescued the pangolin that came to be known as Kulu. He explains that after rescue, the pangolins need an intensive care process at the Johannesburg Wildlife Veterinary Hospital which requires that they be walked every day.
“Because Temminck’s pangolins don't eat so well in captivity you have to take it out into the wilderness and let it forage for its own food. I was pretty much out with pangolins from two to eight hours every day and since I was spending so much time with them and building these relationships I started noticing all this unseen and unusual behavior. I began to film it just for documentation purposes. That's where it started.”
With wildlife cinematographer Steven Dover, Thomas put together a five-minute teaser from footage shot over two years with the objective to pitch it to producers and get a longer form film made. “At the top of our list was Pippa,” he says.
This was in 2021 when Ehrlich, a fellow South African, was a director in demand following the global acclaim of My Octopus Teacher, which highlighted human interaction with a wild animal.
“I was getting a lot of emails from people about films they wanted me to make and I was looking at a lot of teasers,” she recalls. “When I saw Gareth’s teaser, there was a lot about sting operations and trafficking that I felt I’d seen before, but then I looked at the footage of the pangolins themselves and it was just absolutely beautiful and intimate. It was the first time I'd seen these creatures in a way where I actually got a sense of what they are as beings.”
She adds, “I realized that these guys really knew how to capture the essence of what a pangolin is. I spoke to Nick Shumaker [producer at Anonymous Content] and he was also really excited when he saw the footage, that here was a story here worth pursuing.”
While Thomas and Dover continued gathering material, Ehrlich and Anonymous Content secured the commission from Netflix.
“It was Steve who encouraged me to call RED,” Thomas says. “I was still shooting on my Canon EOS R5 but Steve was a very experienced wildlife cinematographer. He knew that we had to shoot on RED no matter what. I made a call to RED and told them we were shooting this film and that we'd love to be able to amplify it.
“It meant that for the final 18 months of production we were hyper-focused on shooting real Blue Chip natural history, incredibly beautiful material, not just of the pangolin but all the other wildlife in the film.”
The biggest advantage of the camera for the filmmakers on this project was V-RAPTOR’s Super 35 sensor for macro photography. “The S35 sensor gave us the ability to crop into the frame so that we could get even closer without always having to put doublers on the end of macro lenses,” Thomas says. “That was the big selling point for the S35.”
The filmmakers shot 8K macro knowing they could crop to 4K in post for delivery. “That gave us an incredible amount of zoom on the macros which was extremely helpful. It's nice being able to have a big frame shooting macro, but when you're seeing it on a smaller screen you're losing a lot of the detail so you want to be able to zoom in as much as possible.”
Much of the activity of the teeming insect world shown in the film as well as the flicking action of the pangolin’s long tongue eating ants happens so fast they shot V-RAPTOR at 240 frames per second in 4K.
“This was incredibly valuable just to slow the action down to something that the human eye can register,” he relays.
Aside from the macro Canon RF 100mm they packed RF 24-105mm and RF70-200 zooms and a 50mm Sumire Prime. “The biggest focus when filming pangolin is to have the most minimal rig possible. I don't even like shooting with a matte box on. It's pretty much just the brain screen and the lens and the top handle. You've got to be mobile the whole time because you're running through the bush.
“You also want to be as close to the ground as possible. It's not a case of putting it on a tripod. To get down to an ant’s level we’d often improvise and steady the RED on bean bags.”
Ehrlich and Thomas began the project with another pangolin in mind. Then they met Kulu.
“I went to visit Gareth at the Wildlife Hospital and while we were there met this absolutely traumatized, hyperactive, inconsolable little animal,” she explains. “He was originally called Gijima (which means ‘to run’ in Zulu). He was the smallest pangolin in the ward and impossible to manage.
“So, I was surprised when Gareth called me up two months later and told me he was taking that ‘crazy little pangolin’ up to Lapalala. I told him to film everything because who knew what was going to happen? The story evolved from there. We were able to get such incredible material of Kulu because Gareth was there for the entire process but also because we had such incredible access at Lapalala Wilderness Reserve. To have that kind of freedom to move around in the bush just makes everything so much more practical.”
Lapalala Wilderness is a 48,000-hectare reserve, a four-hour drive from Johannesburg, where Thomas guided the young creature (now nicknamed Kulu which means ‘easy’ in Zulu) on the next stage of its rehabilitation. The film crew including associate producer CornĂ© van Niekerk secured filming permits and coordinated with the on-site anti-poaching unit to ensure safety for the pangolins and those transporting Kulu.
“It’s a Big Five reserve meaning there are big cat predators, elephants and rhino wandering wild,” he says. “You can't go walking out 10 kilometers in the middle of the night. The entire principle is to carry as minimal gear as possible and make walking through the environment as easy as possible.”
At the end of the film, Kulu is successfully released into the wild and an onscreen title informs us that it is unlikely a human will ever see him again. In the film, you can see Thomas almost tear-up at the thought that this day would come.
“Pangolins are very individual and they are natural loners,” he says. “So, all the ones being rehabilitated get to that point where they want to be wild. Kulu wanted to be wild before I could allow him to be wild! So that was always his ultimate goal and mine too. There's no sense of sadness on my part. Of course, I miss the little guy. He was my best friend for a year and a half and my guide into the wilderness but there's no part of me that is left wanting. It’s just happiness.”
The film was graded by Colorist Greg Fisher at Company 3 in London and produced with the help of the African Pangolin Working Group (APWG), of which Thomas is an ambassador.
The hope is that Pangolin: Kulu’s Journey will bring a new level of public awareness that has the potential to change the outcome for these unique animals.
A special thanks to Pippa Ehrlich and Gareth Thomas for capturing a rarely seen world with intimacy and precision, and for sharing a story that quietly underscores what’s at stake—and what’s still possible—for one of the planet’s most endangered species.
Filming Real Fire: ‘The Lost Bus’ and the Art of Authentic Chaos
