I am having a hard time syncing music to a qt video. Basically I have a

H.264 coded video, and 192kbit 44.1 mp3 audio. I read them both into

separate tracks of jit.qt.movie. At the start they are tight, but towards

the end the movie starts lagging behind. So I fiddled with the movie

"duration" a little to match the ending, and then flattened the movie.

Now the resulting movie keeps on having the same timing issues. In the

beginning its tight, towards the end (5min) the video lags about 0.5sbehind.

What I don't understand is that if I interrupt the movie (by pause or the

timeline) the audio and video are lined up again. This goes for both the

flattened movie and the editing process in jitter (using the frame message

Am I overlooking something obvious? Can I make the sound and video

to jump).

Am I overlooking something obvious? Can I make the sound and video
interlaced maybe? Thanks.

Nevermind. I screwed up the framerate with the video compression. I think

Nevermind. I screwed up the framerate with the video compression. I think
it's fine now.
