AV1 video codec specification released - Royalty Free Video & Better Compression
The final specification of the upcoming AV1 video codec has been finalized and published, it was announced by the Alliance for Open Media with partners like Google, Netflix, Facebook, Amazon and Microsoft. It can potentially replace codecs like HEVC and VP9, royalty free.
AV1 offers improved compression compared to vp9 or hevc, the video bandwidth reduction can run upwards to 30 to 40 percent, without you seeing a difference. The best thing yet, this is a royalty-free model.
For nearly three years, the Alliance for Open Media (AOMedia) has been working in lock-step with its members, the world’s best-known leaders in video, to develop a better quality internet video technology that benefits all consumers. Today, the Alliance is proud to announce the public release of the AOMedia Video Codec 1.0 (AV1) specification, which delivers cross-platform, 4K UHD or higher online video, royalty-free – all while lowering data usage.
Whether watching live sports, video chatting with loved ones, or binging on a favorite show, online video is becoming a bigger part of consumers’ daily lives. In fact, video is so important to users that by 2021, 82 percent of all the world’s internet traffic will be video, according to the Cisco Visual Networking Index™, 2016–2021. To remove many of the hurdles required by older, optical disc-era, video technologies, AOMedia developed AV1 specifically for the internet video-era, paving the way for companies to make more of the royalty-free, 4K UHD and higher video devices, products, and services that consumers love.
“Nearly three years after launching AOMedia, the AV1 codec addresses real bottlenecks for unleashing the highest-quality video for the entire ecosystem, allowing for better viewing experiences across all screens and data networks,” said AOMedia Executive Director Gabe Frost. “By listening to the industry’s feedback in an open and collaborative manner and bringing together leading experts to develop AV1, an entire ecosystem can begin creating video products and experiences that customers love.”
By delivering 4K UHD video at an average of 30 percent greater compression over competing codecs according to independent member tests, AV1 enables more screens to display the vivid images, deeper colors, brighter highlights, darker shadows, and other enhanced UHD imaging features that consumers have come to expect – all while using less data.
“We expect that the installed base of 4K television sets to reach 300 million by the end of 2019 and therefore there is already latent demand for UHD services over today’s infrastructure. AV1 will be widely supported across the entire content chain, especially including services. We forecast rapid introduction of AV1 content delivery to help the widespread proliferation of UHD streaming,” said Paul Gray, a Research Director at IHS Markit, a global business information provider.
The availability of AV1 as an open-source codec is a significant milestone in fulfilling the organization’s promise to deliver a next-generation video format that is interoperable, open, optimized for internet delivery and scalable to any modern device at any bandwidth. Designed at the outset for hardware optimization, the AV1 specification, reference code, and bindings are available for tool makers and developers to download here to begin designing AVI into products.
Specifically, the release of AV1 includes:
- Bitstream specification to enable the next-generation of silicon
- Unoptimized, experimental software decoder and encoder to create and consume the bitstream
- Reference streams for product validation
- Binding specifications to allow content creation and streaming tools for user-generated and commercial video

I wonder how well tablets/smartphones will cope with this, especially older ones with slower CPUs. Probably won't be good for battery life either.
My old Q8400 was already getting 100% playing a 1080p HEVC sample.

My x5470 at 4GHz is around 60%, but it depends on bitrate, RAM/NB latency and CPU clock. A GPU decoder is a must have.

Who even mentioned uncompressed?
The comparison is between AV1/HEVC/VP9 in lossy encoding. And it's a mess out there when it comes which one is the best. As I thought. Depends on who you ask.
No I don't want to see any difference between the compared samples. And if you're comparing the samples fairly your job is to minimize the quality difference (no need for lossless), not to optimize one for bandwidth, and then claim there is "almost" no difference, yet the bandwidth is saved. That's pure bias. You don't know what am I going to do with the video, am I going to edit it or zoom in, and then suddenly I AM SEEING the difference.
You could have just as well optimized HEVC for bandwidth and pretty much claim the same thing, if the codecs are of similar quality, and it seems that they are.
if you doing video editing, u want lossless source in first place
now regarding quality... what matter here is basically "file-size" right ? ... smaller file-size needed to transfer = less bandwith (either counted per-packet or whole size)
simply look back pass enconding
like with HEVC vs H264.... HEVC successful making file size smaller than H264 right
now do you see "quality difference" between HEVC and H264 (at same preset)?
so you think all newer enconder = better "faking" image quality ? which in otherway old encoder = better image quality but poor compression ?
like your claim "Yet this comes at the expense of image quality -> "without you seeing a difference"."

This is possibly very good for people with slow internet and on phones. I tend to download the biggest x264 I can find so I'm not the target demographic but if they can get something with the same quality for smaller files, why not.
Does this mean all TV's out there now won't support this because they are lacking the hardware?
Or does this mean that a TV company has to release an update so some TV's can use this with the existing hardware?
Do we all have to buy new ones when it is finally released to manufacturers?
Chromecasts and other streaming devices exist, so that isn't much of a problem. Smart TV software and hardware usually sucks anyway so cheap streaming sticks and boxes should eventually support the new codec and provide a better experience.
