Huh, I didn't know AV2 was out. What are the new features besides (I assume) incremental compression efficiency?

It’s in the first sentence of the article. Back of the class you go.

  I don't think it actually is. Could you indulge me and quote it here, please?

    There’s some blue text with an underline labeled “AV2 Specification”. That’s called a link. If you click that, you’ll see the date the spec was ratified and some details about it.

      Are you suggesting that I read the whole spec and then read the whole AV1 spec and diff it in my head? Or are you referring to the only text in that link describing differences with AV1: "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"? This is not a description of technical features, it's a high level statement of aspirations. I'm asking what features they added to achieve these goals. I was hoping someone familiar with AV2 might be frequenting this site alongside the much larger population of smartass pedants, and they might be able to summarize the new features in a way useful to me and others.

> AV2 is the next-generation video coding specification from the Alliance for Open Media (AOMedia). Building on the foundation of AV1, AV2 is engineered to provide superior compression efficiency, enabling high-quality video delivery at significantly lower bitrates. It is optimized for the evolving demands of streaming, broadcasting, and real-time video conferencing. > 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.

The general rule for video codecs is that each release reduces the required bitrate by 30% - a release cycle is 7-10 years so each year the research version of the new codec can be expected to improve ~5%.
