So I've got this problem and have no idea how to fix this.
I made a movie in FCP, where everything was fine. The audio had to be mastered so I exported the different channels to AIFF.
So for a test I put my exported movie in a new sequence with the movie settings. Then I put my exported AIFF under the movie and played it. Now after a few seconds the audio starts to go out of sync.
I've tried it on a different computer with new exported audio and everything works fine and I don't have that -out of sync- issue. So my guess it has something to do with my FCP.
What do you guys think?
