"Set for a year-end release, AV2 is not only an upgrade to the widely adopted AV1 but also a foundational piece of AOMedia’s future tech stack.

AV2, a generation leap in open video coding and the answer to the world’s growing streaming demands, delivers significantly better compression performance than AV1. AV2 provides enhanced support for AR/VR applications, split-screen delivery of multiple programs, improved handling of screen content, and an ability to operate over a wider visual quality range. AV2 marks a milestone on the path to an open, innovative future of media experiences."

    I can try it again, but what I did was compare h265 to SVT-AV1 in ffmpeg, using a couple different clips of different styles (including a video from my phone and some ripped blu-ray movies). I used “constant quality / variable bitrate settings, and ran each file with a variety of settings for both encoders. I judged the videos with a quality comparison tool ffmpeg has, and I also took subjective notes when I could tell the difference.

    I found AV1 did better at very low quality (when it was firmly into the region where it was visibly different, AV1 did have better quality per bitrate).

    But when trying to produce high-quality clips, AV1 was never able to produce a clip that matched the quality score of h265, even when the bitrate of the AV1 file was higher.
