Thanks for share-it with us ;)

libaom-av1, did you re-encoded it using ffmpeg? How does your command-line looked-like? something like this?: `ffmpeg -i ${input} -c:v libaom-av1 -preset 2 -crf 30 ${input}[AV1].mkv` I tried AV1 encoding, but it always use CPU and is slow as hell...

If it's slow as hell to you, you either go libaom preset 5 or use libsvtav1 preset 5 or 6. Simple as hell.

libaom preset 2 : bitrate= 28.3kbits/s speed=0.0459x libaom preset 5 : bitrate= 28.3kbits/s speed=0.0543x libsvtav1 preset 5 : bitrate= 11.2kbits/s speed=0.541x libsvtav1 preset 6 : bitrate= 8.8kbits/s speed=0.924x Thanks @NekoTrix, indeed, libsvtav1 is a better choice for me by far! would still love to pass it on my GPU instead of CPU, but according to nvidia's GPU support matrix, my old card does not support AV1 encoding u_u (AV1 encoding support only starts from RTX40xx)

i use a gui that use both ffmpeg and av1an av1an allows multithreading of the encoding GPU encoding does not give the same quality, i own an rx 7900 xtx and i still encode with my cpu because it s not made for that purpose here i want high quality for little size no matter how long it takes with my ryzen 7900x with preset 2 i got 9fps on this anime which is pretty fast some people that encode in av1 take two days for one episode.

this encode took me 2 days

OOF 9fps? OK, so it IS normal. i was thinking there was a perf issue with my stuff, since it's old and all... Thanks for sharing =)
