    The new King of Codecs: AV1 (Patent Free)

    With a patent defense system in place to keep it free, AV1 looks to surpass H.265 as the next major codec for cameras and the web.

    Another high performance version, written in Rust (vs. C/C++): https://github.com/xiph/rav1e

    I discovered AV1 when researching codecs for video streaming for iOS (haven't found an ARM/iOS GPU accelerated version yet, though Apple has recently joined the AV1 project).

    Apple, Samsung join AV1:

    Netflix, Google, Microsoft, Amazon, Apple, Facebook, Samsung, Cisco all behind AV1: https://www.cnet.com/news/netflix-yo...1-compression/

    Enough leverage to keep patent pools from interfering with freedom.

    This is amazing and exciting for those involved in media!

      AV1 Ecosystem Update

        So it's a new delivery CODEC ?

        I was kind of p*ssed this month when I found out that Final Cut Pro X no longer supports Cineform or DNxHD CODECs, so the past 6 years of projects can't be opened with FCPX any more. ( I don't work with FCPX, but one of my regular editors does )

          The open source Cineform could have been cut because it out performs (closed source Apple owned) ProRes by 1.25 - 2.3x in efficiency (I've verified this- anyone can replicate these results). I guess that's good for storage manufacturers ;)

          AV1 can be used anywhere H.264/H.265 is used. In a camera, for delivery etc. With its sophisticated encoding tech (very flexible macroblock sizes and patterns), even ALL-I (intraframe) might be useful as a fast, small file size intermediate codec (another more modern/efficient competitor to ProRes). Since it's free with 'patent protection' everyone of note is jumping on board- lots of rapid development progress too. Even Apple and Samsung jumped on board recently (they're part of the H.265 patent pool and likely VVC (the real competitor to AV1).

            What happened to VP9?

              What's the AV1 CPU/GPU load like compared to h.264 or h.265 ?

              I still find h.265 to be a burden on my workstation when I've got a few 4K videos layered on top of each other. ( which is one of the reasons I've been transcoding to Cineform for many years now )

                Look like VP9 is still being used on YT until AV1 gets performance optimized: https://www.youtube.com/testtube (AV1 only available for SD videos (when opting in)).

                AV1 appears to be more efficient + has patent protection = apparently why everyone's jumping on board. A patent pool company might try something, however given the powerful companies behind the patent protection, appears unlikely they'll prevail.

                https://en.wikipedia.org/wiki/VP9
                On September 12, 2014, Google announced that development on VP10 had begun and that after the release of VP10 they plan to have an 18-month gap between releases of video formats.[101] In August 2015, Google began to publish code for VP10.[102]

                However, Google decided to incorporate VP10 into AOMedia Video 1 (AV1). The AV1 codec will use elements of VP10, Daala (Xiph/Mozilla) and Thor (Cisco).[103][104][105] Accordingly, Google has stated that they will not deploy VP10 internally nor officially release it, making VP9 the last of the VPx-based codecs to be released by Google.[106]

                  CPU load for AV1 is likely to be slower than H.265. However, unlike H.265, many companies are scrambling to optimize AV1, including Intel (since it's open source / not patent controlled / owned). Remember H.264 took quite a long time to 'get fast'. Due to the widespread adoption, expect to see AV1 performance improve faster than any codec before it. It's already available on YouTube for SD videos.

                      Wasn't VP9 available to anyone without patent issues? Or is my memory failing on this.

                      I wish we would see additional codecs that are truly open, especially really good acquisition and DI codecs (could be one in the same).Also good open consumer codecs (maybe AV1 will take this place from h.264/h.265 which are an mpeg license). Would love to see Avid truly open the DNx system, only some parts are truly open (the LE codecs).

                        I got about half way through the wiki, but I did pull out some things of note:

                        #1 they left room for lossless compression

                        #2 they built in a profile that can handle 444 at up to 12 bits

                        This is also troubling:
                        Patent claims
                        In March 2019, Luxembourg-based Sisvel announced the formation of patent pools for AV1 and VP9. Members of the pools included JVCKENWOOD, NTT, Orange S.A., Philips, and Toshiba, all of whom were also licensing patents to the MPEG-LA for either the AVC, DASH, or the HEVC patent pools.[149][150] Sisvel announced it would demand €0.32 for display devices and €0.11 for non-display devices using AV1, but would not seek royalties for encoded content. At the time of the announcement, a list of patents owned by Sisvel was not publicly available. However, Sisvel's CEO stated in an interview that such a list would be posted on Sisvel's website before any licensing demands were sent out.[151][149]

                        As of 8th April 2019, the Alliance for Open Media has made a press release, which reiterated the commitment to their royalty-free patent license[152], and made mention of their "AOMedia patent defense program to help protect AV1 ecosystem participants in the event of patent claims", but did not mention the Sisvel claim by name.[153]
                        I hate people that take free stuff and pretend to own it!

                          VP9 was free, however only Google was behind the patent defense.

                          AV1 incorporates part of VP10. The VP series is concluded.

                          Cineform is a great DI codec.

                          With Google, Facebook, Apple, Samsung and more supporting the patent defense, AV1 is likely to remain free.

                            I strongly doubt that Apple is a proponent of any free codecs, it would be a first.

                            AV1 is going strong, Android Q will have it built-in.
