   FFMpeg wiki: "For source files of 1080p and 720p av1 optimization is not optimal, most of the time is better to go with the H265 for better vmaf/size ratio"

   Here, av1 is 330mb, h265 is 620mb.

   I used hardware acceleration for HEVC but I doubt it would make that much difference

     @matrix a word of warning that the ffmpeg developers tend to be huge h26x simps. they consistently put in little to no effort on other codecs, which also ends up reinforcing the bias because: someone says encode a random h26x with no details and its tuned for quality, you say a random vpx and its defaulted to some bullshit bitrate that looks awful, and then everyone goes gee darn i guess everything looks bad.
     
     they also boned this up once with convincing people flac was not lossless because ffmpeg erroneously was injecting bitrate conversions that were not asked for

     @matrix interestingly in recent versions of the aom encoders they added support for butteraugli (jpeg xl's perceptual metric), so they are doing perceptual encoding tests in the reference encoder nowadays. hilarious to see jpeg-xl as a dependency for avif :blobcatlaugh:

     @icedquinn @matrix to be fair iirc those defaults are in vpx itself. Vpx is a shit encoder tho.
     
     I've had great success with AV1 and SD content.
     
     Also svt-av1 has had so much development that info on AV1 encoding from 2 years ago is practically useless.

     @sjw @matrix i lifted my avif encoding stanza from someone who tested different avi1 encoders and ran them all through some perceptual thing
     
     AOM apparently is absurd about maintaining perceptual quality, it's just too slow for practical use.

     @sjw @matrix though as i keep saying av1 encoding most likely would benefit from some small amount of AI work. the filter chains are absurdly complex in av1 (god help av2, currently WIP) but i'm not convinced you couldn't just train some models to predict filter layouts that were good enough.
     
     prblem is that spec is 900 pages of sheer pain so idk

     @icedquinn @matrix oh yeah there's no disputing that aom produces the best quality. At least with tools like av1an it's kind of usable but it's still too slow to be practical. Cool to see what's possible tho.
     
     Vimeo apparently has decided to use rav1e which does give better quality than svt-av1 and is still being actively developed.
     
     IIRC aom is fine for real-time encoding use. I think it might perform the best in terms of speed and quality at low bitrates out of the three for encoding in real-time.

     @icedquinn @matrix just have AI read the spec and then train an AI for the tasks needed. Simple as that.

     @sjw @matrix nothing simple about that in the slightest :blobcatgooglybadumtss:
     
     the specs just tell you how the information is decoded. they don't tell you much of anything how to encode it. that requires big math brains to work the shit out.
     
     i have a small math brain, but thats a full time job and ain't nobody paying me to figure out how to encode their anime and tiddy streamers
