|Summary||0008820: AVI/MJPEG produced a lot of dropped frames, ProRes/MOV does not|
|Description||I've been having issues with video playback via Xjadeo when usign video reference ith Ardour.|
In the past it worked ok, but not now.
When using default Ardour MJPEG transcoding, Xjadeo produces a huge amout of dropped frames, resulting on terrible image flicker.
I've tested a different codec and it worked flawlesly (also provided much better visual quality):
My input is a 1080p60 MKV file. I've transcoded it with:
ffmpeg -i reference.mkv -s 854x480 -pix_fmt yuv420p -c:v prores reference.mov
I do what I can to avoid non-free codecs, but in this case the MJPEG encoding seems to work poorly. I don't know why, as it used to work great.
Please consider testing this and changing the default transcoding settings to make sure other users don't have this same issue.
