Audio changes length on export
Hi, my client has a Final Cut timeline with a bunch of different audio in it. We don’t want to media manage the timeline to ingest it into my system. Instead, we’d like to just export an AIFF from his timeline and hand the file over to me.
We’re both working off the same timeline settings (DV NTSC). His timeline is 46:50 in length (minutes/seconds). After exporting, I received the file and it’s 46:52;25 in length (2 seconds, 25 frames longer). Anybody have ANY idea what’s going on and how to fix this?

Sounds like Drop Frame vs Non-Drop Frame timecode to me. He might be in Non Drop and you’re in Drop (indicated by the ; in the timecode).

Is your friend working in a non drop frame timeline? Are you working in drop frame?
Another possibility is that his timeline actually is 2 seconds, 25 frames longer. Perhaps he has a piece of media hanging past the tail of the timeline that he didn’t notice? Or at the head? Does the media start at the very head of his timeline? Or perhaps 2 seconds, 25 frames later?
It’s hard to really tell without looking at his timeline.

I’ve looked at his timeline.
I’ve even made a new timeline and threw in some random songs on my hard drive. I set in/out to 46:50 in total. When I bring the AIFF back into FCP (not necessarily putting it into a timeline), FCP shows it as 46:52;25. Everything’s being done in dropframe (my timeline, his timeline, test timeline).
P.S. Text size on my monitor is small, hard to decipher between ; and : =P

Have you converted the songs? CD audio is 44.1 kHz and FCP audio needs to be 48.0 kHz. If the length is different on the AIFF, it might be set up to export at 47.952 or 48.048. Open the AIFF in Peak Express (which I believe is still bundled with FCP) and look at the audio sample rate.

All audio is at 48 KHz. But i’m still exporting from a Final Cut Pro timeline that contains multiple edits/cuts. Even if I use just a slug, the length of the file ITSELF changes by a significant amount.
