A bit off topic, but in your talk you said that intel, nvidia and amd encoder are worse than svt-av1. How much worse and which card is the best? Always encoding

A bit off topic, but in your talk you said that intel, nvidia and amd encoder are worse than svt-av1. How much worse and which card is the best? Always encoding with ab-av1/av1an using svt-av1, but with the "right" preset it's still really slow. Which hardware encoder (in your opinion/experience) is the best to use (size/quality speed doesn't matter as much). If I want to convert my media server to av1 only should I stick with svt-av1 and eat the power/time-cost?
- cstejerean 4y agoWhat is the the "right" preset? SVT-AV1 has a wide range of presets, from being about as fast as x264 veryfast onwards. And for any given speed level it should provide significantly lower bitrates at the same quality than x264, x265 or libvpx. For example if you pick speed 6 on SVT-AV1 it should take about as much time as x264 veryslow while still being 30-40% lower bitrate at the same quality. Have you tried the faster presets of SVT-AV1?
- brucethemoose2 4y agoI dont have a card to test, but the last VMAF bench I saw shows hardware AV1 is slightly better than veryslow x264. Which is way better than hardware h.264... but also terrible compared to svt-av1, lol. Try using av1an to parallelize (and improve the quality of) your encode. And TBH you should not re encode your library unless it has raw rips or something like that, and you are short on space.
