We had this problem recently too. The offline audio was in sync yet when = it got sent to the audio studio for sweetening it came back to the = online 2-3 frames out of sync. The editor had to go and manually slip = every clip into sync.

Was something to do with the = 24fps pulldown if I remember.

Greetings to all.

I'm = assisting on a film and the audio round trip to Pro Tools isn't syncing. = I'm hoping someone has some insight into the problem. Which = is:

The film is 24 fps. Audio 48k 16 bit out. = 48k 24 bit back.
To isolate the problem, we created 3, 5 = and 7 minute clips. Each clip begins with a standard Cinema Tools = countdown with a one frame beep at the 2. Following the countdown is = black with a time code. After the allotted time of the clip, there's = another 1 frame 2 with a one frame beep.
We sent this off to = the sound designer who, in Pro Tools, matched the beeps in his set up, = then sent the audio file back.

When I line up = the files we sent with the files he sent in After Effects, they match = perfectly.

In FCP, however, they're out of sync = =96
In the 3 minute clip, the sound guy's beep sounds 5 = frames before the beep at the end
In the 5 minute = clip,  the sound guy's  beep sounds 8 frames = before the beep at the end.
In the 7 minute = clip,  the sound guy's  beep sounds 11 frames = before the beep at the end.
Not only that, but the = waveform appears visually in the right place in the timeline of the 5 = and 7 minute clips, while the actual audio sounds 8 and 11 frames = earlier, as noted above.

Does anyone have a = clue what can be done to fix this problem? We can't sync the film until = we resolve this issue.

Many thanks in = advance.

On our end:
FCP = 7.0.3
QT 7.6.6 Pro
AE 11.0.0.378
iMac = 10.7.4
