Multicam losing sync
I’ve got 2 clips, approximately 1 hour long. When I sync to in points and create multicam clip, as the time goes along they get further and further un-synched. I’m talking 2-3 seconds by the end of the hour clip. Both cameras recorded drop-frame. I digy-ed using the firewire from my panasonic aj-d250 deck. No fancy frame rate, just 60i. Even the video and audio on the same clip get un-synched. I have plenty of memory and plenty of processing power. The system has no problem (no freezing or crashing) playing them back. what gives?

OK, after checking the original clips (which is what I should have done first), it’s not the multi-cam that’s messing up, the clips themselves are off sync! How did that happen? I checked all my capture and sequence presets and they’re identical. Again, i’m using a panasonic AJ-D250 via firewire into my mac. I’ve been doing this since I got the system. The only thing i’ve done recently is upgrade to OSX-Tiger.

I don’t know if this will “help”, but I’ve had the same problem when uploading footage from the Panasonic DVX100 and syncing it with a Canon or Sony camera. Something about the 24 frame rate (even though it is recorded at 29.97 and 16 bit/48kHz audio) seems to do something with it. We recently purchased a few Firestore hard drives, and when pulling the footage from there from the Panasonics, we haven’t had any problems.
What I had to do in the past was go every 6 minutes or so and slice the Panasonic’s track and move it forward 1-2 frames to keep it in sync. But that was my “fix”, and I am sure there are better ways….
Sorry I couldn’t be more help, but hopefully it points you in the right direction.Tim

Your drives are too slow or your clips are too long. If you log the in and out points and then batch
the single long clip, that sometimes works.Some people can capture a full hour long clip with FireWire drives while others cannot.
Depends on the drive, and if you are daisy-chained to a slower camcorder or not.
Get faster drives, like a G-RAID and get a FireWire PCI or PCMCIA FireWire Card
for an additional bus to separate your decks and drives. A separate internal drive works well
in my experience.As FCP becomes more sophisticated, FireWire drives are becoming less reliable, IMHO. Especially
for multicam. All the stars gotta line up.Kevin Monahan
