sync drift weirdness in fcp
i just figured something out, kinda. in final cut pro 6, when i sync up a 28/24 audio clip to video shot at 29,97 fps, it drifts out of sync by 1 frame for every 30 seconds. after 10 minutes of an interview you're 20 frames out of sync.
puzzled all over the application to no avail, until i tried one stupid thing:
i did a speed change to the audio clip, asking it to be exactly 100,1% of its normal speed.
after that it was dead nuts in sync.
by the way i've never had this sync drift issue when working in aftereffects. only in fcp.
i wonder if it also occurs in other video editing apps.
update 01 dec 2012:
i'm finding that to sync with clips at 25 fps i need to change the sound clip to 99,91% of its natural speed.
