23.98fps / 24fps Sync
I have a 23.98 MJPEG A lo res QT, it was rendered from AE @ 24fps and then conformed in Cinema Tools to 23.98 to sync with a 23.98 24bit WAV file. Have set up a sequence in FCP 5.1.4 at correct size, same codec, 23.98 editing timebase and same spec for audio file (24bit).
After 10 mins sync starts to drift and by 20 mins it is out and appears to be a 24/23.98 issue but I cant find out where the slip is.
If I set up another sequence @ 24fps editing timebase and drop the same clips in it syncs fine. Anyone seen/heard this before? All help gladly welcomed!

I might have just had the issue you speak of but slightly different. Took me friggin ages to figue it out, and I am still not exactly sure what did it.
Basically to fix it:
I made sure that every single setting in the easy setup (or audio video settings) match my time line exactly (codec, frame rate, frame size). It didn’t seem to work if I just set most of the setting only. Then I removed ALL audio from the project (both bin and timeline).Then completely exited FCP and restarted it.
Imported the audio into the bin again (and it was a completely different duration) I did the calculation and it didn’t seem to have change by anything that made sense (it was more than 23.98 to 24 less the 24 to 25….who knows?!?).
I find it soooo hard to believe this error isn’t reported every day (well I guess it has taken me over 4 years to find it.
Not sure if this helps but see if you have any luck. I would be interested to know.
Let us hope this issue is fixed in 6!!!

To add to this.
When the audio was importing incorrectly. The waveform the FCP generated was completely incorrect. It was several seconds out (and it just so happened I was doing these adjustments from a firewire drive that couln’t get playback so I was actually lining up using the waveform….ahhrrgg).
So I think it is definalty a bug and not just user error…which wouldn’t have suprised me…as I do those kind of things all the time.
