So...yeah. Looking at file size, it clearly beats older 264 or even 265. I don't mind if my server is going to have to transcode for most clients, I think the size difference in size might be worth it. But not sure which groups I could focus to look for these AV1 releases, seem they're quite scarce still?
For most stuff i release, x265 objectively (vmaf and other metrics) and subjectively looks better than av1, especially for grainy stuff and older anime. I have had success only with some action movies.
Opus on the other hand... it's great
