[Avid-L2] Re: sync problem

 

Sync issues in FCP seem to be cured by (not an exclusive list):

fill gaps in video track with 'slug'
mixdown audio (alt apple R)
set audio playback to 'high'

Not sure that will fix your problems though.

One other thing I would try (not sure if it works for .wavs) would be to paste the audio tracks into the QT- within QT PRO.

Or - line up the .wavs on the timeline so the waveforms are correct then export a QT ref. (You'll need to be set for multi-channel output rather than stereo, with the routing on the tiimeline correctly set.)

This does an export of the audio but only pointers to the original video - then bring that QT Ref back into FCP and see how that behaves.

The stems and the picture are out of synch with each other in Final Cut Pro 7.0.3, but the waveform display in the timeline synchs up. When I bring the very same files into the Avid via AMA, they are in perfect synch, as expected in the first place. The audio files are wav's with timecode.
