I did a project which consist of two video clips (1080p h264 mov stereo) some title and a other video clip (xvid avi mono). I used the composite transition to have a pip effect. This works good with the two videos from the same source, but in the moment i use the mono video clip in the composite transition the final video contains only the sound from that clip. The sound from the stereo video is no included in the rendered video but it is played in the projectmonitor.
I hope I made my problem understandable. And someone can help me.
EDIT: I tried to fix the issue by disabling sound for the mono video, adding a mono to stereo effect, but no luck.
I also didn't mentioned that the xvid clip is 25FPS and the mov video clip is 29.97 as the project too.
