sync problem….
Strange thing: I opened a FCP 4 project and files from a clients LaCie firewiredisk on my dual G5 with FCP 4.5 HD.
(Clips are mini DV and had been captured from Canon XM2-cameras).
All the clips had out of sync audio (about 5 to 6 frames).When reviewed in FCP 4 with the original computer that captured the clips (also a dual G5) they were all IN sync…
I work with LaCie disks all the time and they’re great, can’t be it.
I never encountered this problem before and I can’t seem to find a resolution.
I wonder if anyone could help me with this; any comment is appreciated -

Are you monitoring on EXTERNAL audio and video (or on the computer for both audio and video) on the second computer?

.. I’m working with clips in a project from a firewire disc; clips have been captured with audio and video in one file (DV Pal (I’m in Europe) compression, 25 fps,48.000 kHz, the correct way). So, the clips have timecode and there’s no “out of sync” label appearing in the timeline but it IS out of sync.
(I hope I’m still making sense here). -

I wanted to know so I could emininate the possibility that the “lag” between the Canvas and the External (audio) Monitor was not your problem.
If you’re viewing/listening ONLY on the computer (with no FW deck or camcorder connected to the Mac, I’m stumped.

I think it’s the same delay than working with AJA (firewire as well) You have to set the user settings in FCP the magic 7 frames, then it’s in sync. The external works in the same way, over fire wire. If the out of sync is constant you can fix it within FCP settings.

yes, but I encountered the same problem (audio out of sync) today while capturing and previewing from a Sony VX 1000 through firewire… never had that problem before. Checked my settings again, they were ok. Could it be a bug in OS 10.3.9????

Didn’t hear good news of 3.9. I’m glad I’m still on 3.8. Up to now there is no reason to update.
good luck,Rainer

This seems to be a playback problem in FCP. I have the same problem with DV50 footage captured through an Aja Io.
The annoying thing is that the sync just suddenly falls apart. Your whole sequence works fine, and you’re editing away. But some editing manuever seems to mess up FCP and then the audio is about six frames ahead of the video all through the sequence, and there’s no way I can find to eliminate the problem.
And the problem doesn’t seem to be constant; the sync seems to be worse some places than others.
I’m monitoring using the build-in audio and the canvas, AND an external monitor. Sync is off the same way all around.
If you render your sequence out to QT, though, it’s in sync.
