| 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. | ||||
