ADR sound out of sync in FCP but not DVDSP
We shot on a Canon 55D at 50fps that I converted to 25fps and gave to my sound designer to sync ADR dialogue and do sound design on.
I received all the sound back in a single .wav file that I imported into FCP7 and lined up with the 25fps export that I gave to the sound designer. The sound is perfectly in sync for 4min and then slowly goes out of sync for a minute and then back into sync for the last 5 minutes of the film.
The same clip and sound file is perfectly in sync in DVD Studio Pro’s timeline, so the problem does not lie with the sound department.
Does anyone know how to fix this problem or why it occurs? I would appreciate any leads on why this could occur.
Thank you in advance.

If your sound designer worked in a program that had a “sync” option, and it was set to NTSC specs, i.e. 23.97 fps or such, then FCP reads that sync info and it would cause exactly the problem you’re describing.
I’ve had the same problem before, causing me to pull my hair out. If you open the .WAV file in Finder, it should be the correct length. But when you pull it into FCP it magically changes length.
Get your sound designer to change his settings to 25fps, re-export, and all should be fine and dandy.
