Avidemux 2.7.x cannot handle the new Youtube video codec, e.g.


Any suggestion how I can edit this video clip with Avidemux?

If you mean AV1, then no, this is not supported yet. Adding support for this codec is on radar, however, but waiting for broad availability of graphics cards which would allow decoding and hopefully also encoding AV1in hardware (without help from a HW decoder, I get only a slide show for HEVC and also for AV1 at or above 720p).

Download a version of this video compressed with a different codec (preferably H.264).


Thanks for your fast and detailed reply. Yes, it is AV1 with 1080p. And thanks for the hint to use a different video type, I will do that.

Hi to all, I have problems to open mp4 videos with ogg (YouTube) audio. The application crash:
This is one of file with ogg audio that crash the application
I want to change container from MP4 (AVC + Ogg) to MKV (AVC + Ogg) my solution now is to use this command with ffmpeg64.exe:
ffmpeg64.exe" -i "E:\Video\2014\Ellie Goulding - Burn.mp4" -vcodec copy -acodec copy "E:\Video\2014\Ellie Goulding - Burn.mkv"
but I would like use Avidemux.

@cyberfer, please don't hijack unrelated topics, start your own, thank you. The ability to handle Vorbis in MP4 has been added to the demuxer by commit [demuxers/Mp4] Support Vorbis audio tracks, will be present in future nightlies and releases.

Please note that it is not possible to save to MP4 with a Vorbis audio track yet.

@pantau, decoding support for 8 bits AV1 was added to Avidemux code approx. two weeks ago, it is already available in current VC++ nightlies and will reach other platforms except of 32 bits Windows once their build environments get updated.


Saving as MP4 with a Vorbis audio track should work now.
