Yah rav1e is a bit faster, only a few weeks ago I tried to transcode large test movie was around 8 gbps of h264. I was using a big 20 core e5 and was doing almost 1/2 a frame per second. I seem to recall working out the estimated time to encode to AV1 was about 3 weeks...

Thanks, it compiling this was a bit of a pain but I got it and do see some performance increase but wow slow. Still though, I know this is outside the scope of the article but I don't see AV1 catching on anytime soon and I half laugh to point out that 2027 when h264's patents expire isn't that far out! Everyone talks about hardware encoding options for h264 being available, let's not forget how crappy the output from h264 hardware encoding is compared to software encoding.

YouTube already has many of its videos encoded in AV1 up to 720p. Try it yourself with Firefox 67 beta, or any other browser which uses the dav1d decoder.

Turn on AV1 on YouTube (set it to "Always prefer AV1"): https://www.youtube.com/testtube

Try the AV1 playlist: https://www.youtube.com/playlist?list=PLyqf6gJt7KuHBmeVzZteZ...

Pick any popular video on YouTube (like a music video) and play it. Check the format with right-click -> Stats for Nerds. If it's AV1 the codec will be "av01".

On my 5-year old laptop, AV1 in Firefox 67 beta is fast enough for 1080p30 and almost fast enough for 1080p60.
