Hi all, I have a strange problem when using Kdenlive, but which I think is due to MLT: I have a recording of a singer from two angles and I want to switch between them. However, AV never is in sync. There are problems with a scenario as simple as the following:
Put a video on track 2, and the other on top of it on track 1. The position of the 1st is aligned (delayed) to the 2nd. Audio from both videos is active. Then I cut "holes" into the 1st to show track 2. The result is as follows: * In the render output and the project monitor (if the project is played from the beginning), AV gets out of sync only on track 2 (the audio belonging to the video!), but the two combined audio sync is fine. * If I seek to arbitrary positions (position with either holes or no holes, active video 1 or 2, respectively), AV sync on track 2 is fine, but A and V is not in sync with track 1 when it is active. So, either way, I can not reliably sync the two tracks. What can I do? Note: Track 2 material is obtained from a camcorder. It consists of several MPG files joined with the ffmpeg concat demuxer and transcoded to x264. I also tried -vsync cfr. When playing in melt or ffplay, video gets out of sync occasionally, frame drop is increased (ffplay fd=X value), and then resyncs. Thanks for your time.
