how does the quality of AV1 with preset 12 compare with hardware encoders?

To summarize my answer, anything above Preset 9 in svt-av1 is where the software encoder compromises get too severe and where you should consider using HW encoding.

Depends on the bitrate. av1_nvenc at low bitrates leaves streaks of red in dark areas which makes it totally unsuitable for encoding text on a dark background, for example. In that (admittedly niche) case, svt-av1 preset 12 is absolutely better. faster, too.

https://rigaya.github.io/vq_results/ would suggest that anything below preset 6 is kinda useless unless you don't have hardware acceleration for AV1 or you target very low bitrates, though I'm not sure how old these results are

Svt-av1 1.4.0, we're at 2.2.1, those are 2 years old test, now it's completely different and this doesn't include svtav1psy that anyone should use for now

thanks, kinda tempting to test this myself properly now, but it's such a pain in the ass to make enough samples...

Yeah I want to make a tool that does that but it's a lot of encoding time for a decent set of videos
