Re: Guide to Adopting AV1 Encoding
#2Maybe this is not such a concern to audience of this article, but at least for me I'm stuck with h264 because VP9/AV1 encoding is really really slow. I'd love to use the codecs that are open and technically better, but when the video encodes at 1fps, it's too just too convenient to use the magnitudes faster h264.
I'm probably not up to date with newer/hardware encoders and please let me know if my view is outdated.

The hardware encoders are very fast and generally better than x264 (but not by as much as you'd think with the x264 slow preset).
In addition, there are fast threaded AV1 encoders you may be overlooking, like SVT-AV1. For non-realtime, my favorite is av1an, which also yields better quality than is possible from aomenc and works with pretty much any encoder/codec: https://github.com/master-of-zen/Av1an

1. Compile this: https://gitlab.com/AOMediaCodec/SVT-AV1
2. ffmpeg -i infile.mp4 -map 0:v:0 -pix_fmt yuv420p10le -f yuv4mpegpipe -strict -1 - | SvtAv1EncApp -i stdin --preset 6 --keyint 240 --input-depth 10 --crf 30 --rc 0 --passes 1 --film-grain 0 -b infile.ivf
3. ffmpeg -i infile.ivf -i infile.mp4 -map 0:v -map 1:a:0 -c copy outfile.mp4

Tricks of the trade: why have one computer compress the file when you can split it up into logical segments and have each segment sent to its own encoder?

#7> YouTube for example, encodes content in H.264/AVC, VP9 and AV1
Why don't I see AV1 in many Youtube videos though? Checking with yt-dlp. It looks like they were planning to use it, but didn't really roll it out.

Haven't tested it yet. I'm waiting for OBS to enable hardware accelerated AV1 encoding on Linux.
