Howard Sonnenburg from Atomic Audio has posted this question…
If you are working on a project cut in FCP at TRUE 24fps (i.e Animation, or for finishing on Film via Cinema Tools) and you have exported you mix as a .WAV or .aif at that framerate… FCP puts a timecode value on audio it has imported. This value is the fps in the default capture settings -regardless of the fps of the Sequence. On most systems this will be either 29.97 or 23.976. However when you add this to a 24fps sequence FCP decides “Oh this audio has been pulled down, therefore I must pull it up to match with the 24fps timeline” – even if the audio is synced to a 24fps timeline originally. Yes, this includes BWAV files output from PT. The result is that the audio, which matches perfectly your QT movie in PT, and even in QTPro will play out of sync in FCP. Yes you read that right… FCP WILL pull up your audio without asking! So how do we work around this?
1. Have your editor make sure his default capture setting is the same framerate as his Sequence (good luck with this one…)
or
2. In QTPro, export your .aif as a .mov with the correct frame rate.
or
3. Use the Sebsky tools bwf2qt function to export an FCP movie with the correct framerate.
Gotta love that technology! Just thought I’d share this for those who may have had these weird sync issues in the past. You are NOT going crazy…
For all the details go and have a look at the thread on the Digidesign User Conference.
There is loads of discussion and advise in the thread and Howard has posted his solution which is to use point 3, he says…
Simple fix…
1. Export as .WAV (yes .WAV)
2. Open Sebsky Tools (click to download here)
3. Choose bwf2QT under tools. Check your settings, esp. that Timecode standard is set to 24fps.
4. Convert.
5. Give to FCP Editor.
I recommend anyone using exports from Apple’s Final Cut especially at 24fps frame rate take a good look at this thread.

Seven radio producers – all based in the north of England – have joined forces to launch a new co-operative venture – ‘Radio Wizards’. It’s equally remarkable that their aim now is to work together on every kind of sound production... except radio!
"It’s taken over a year to get to this point," says ‘wizard’ Mike Thornton, "but now we’ve got a viable business plan, we’ve launched our website and we’re already starting to attract commissions. As a facilities provider we decided to facilitate this partnership and set them up with a web site to help kickstart this excellent partnership."

FCP needs an ‘Interpret footage’ function, like in AE and Premiere, where users can specify framerate, pixel aspect, pulldown field order etc.
