Thanks very much.
ffmpeg? The macports ffmpeg install includes libaom-av1, rav1e and libsvt-av1. I'm doing a test transcode from an h.264 mp4 with default settings and it's **really** slow on my 5K iMac -- about 1-2 frames/sec.
Yeah, its CLI commands can be pretty confusing. But they can also be pretty simple. I just used:
ffmpeg -i input.mp4 -c:v libaom-av1 ~/Desktop/output.mp4
-i to tell it the next thing is the input file
-c to tell it the next thing is a codec, :v for video
libaom-av1 is the codec
and finally what the output should be and where to put it. It knows I want an mp4 because of the .mp4 output filename extension.
(The transcode I started 20 minutes ago is still only 1/4 the way through a 7 minute file... )
Per what's posted, VLC 3.0.0 has the first (experimental) AV1 support.
Good to know, but it looks like it's decoders only for the time being. It's not free, so that might be preventing it. Apple doesn't support the format, so QuickTime can't even play it back. It looks really good, even for an 8-bit codec. I don't know if there's a 10-bit version. It's not as small as H.264, but I think it's better at gradients and other difficult material from what little I've seen.
Thanks very much Terry. That could probably work, but I can't use FFmpeg. I can't make sense of it. And it also looks like it's the end of their cross-platform development as they're not going to support silicon.
Good thought, but I'm not seeing AV1 in their offerings.
Thank you fox. That seems to be working. It's slow though as Terry said.
16 minutes to do 21 seconds of 4K.
And it's not encoded correctly.
A work in progress I guess. That said the bit that did encode looks better than the original.
Handbrake added AV1 support a few months ago:
That's all I know about it.
Anyone know how to convert media to AV1 on the Mac?
