Audio drifting out of sync on 30 minute captures of HDV footage
Im trying to digitize some footage shot on the Sony FX1 HDV camera…it is an hour tape, I am digitizing it in 30 minute increments, for some reason the audio on the second capture is drifting out of sync…..I have no idea why. I have done this before with no issues. Using FCP 5.03, all updates current…. the footage was shot HDV but is being downconverted during capture…any ideas?

“Sync-slippage” can happen during some longer captures.
Tapes recorded on certain camcorders from Canon have been somewhat more problematic but it also can happen with other brands of cameras as well.
To reduce the problem on capture, break your captures into sections no longer than about 10 minutes each.
You can then “reconstruct” the full tape’s recording (or any longer takes) quickly if you need to.
Mark (and log) your first clip to End (Out-point) about 10 minutes or less from its In-point.
Continue to mark (and log) your clips this way throughout the rest of the tape.
Just make sure the In-points of the subsequent clips are EXACTLY ONE FRAME LATER than the Out-points of the previous clips.You can do all this while actually scanning the tape(s) or just by inputting arbitrary TC numbers, logging them… then use Batch Capture to bring in all of your clips.
Its very easy to then “reconstruct” the shorter clips back to any “continuous” length you want on the timeline by just “clicking” them on in order.
EVEN FASTER… select ALL successive clips at once in the browser (with the browser column-order set to “Media Start” highlight all clips) and drop them, all at once, on the timeline… they’ll all pop up in continuous order.
