I am having a problem with audio sync. My video is about 6 minutes long so far, made from mainly still photos with a few video clips. It is synchronized to a WAV music file. Some of the sync'ed photos are only 16 or 17 frames long (slightly more than 1/2 second) and I spent a lot of time to sync them very precisely.
In the preview, the sync is perfect. When I have produced an mpeg4 video, the sync gets off. It is only off very slightly, and it is only off for approx. 30 seconds in the middle of the video. It is only off by a slight fraction, (photos arrive slightly late) probably 2 or 3 frames out-of-sync, but since the timing of the sync is so precise, it is very noticeable to me. By the final minute, the sync is back to where it should be.
Any suggestions?
Thanks,
Tony
