Captured XL1 footage A/V sync difts
Howdy Cowpokes,
I have XL1 footage that seems to have recorded audio at 32 K since capturing with the DV 48 K preset gives me the error message that my original source differs from the capture preset.
My consumer model DV camera reads 12 bit sound during playback (which is of course perfectly in sync). But nowhere do I see an option to input 12 bit sound at 32 K in FCP’s A/V Settings

Just to add to my intial post

You can only capture 2 audio tracks at a time.
You can set the capture preset to Audio 1 & 2 -or- Audio 3 & 4.BUT, 12 bit/32k does not mean that there ARE 4 tracks RECORDED, it is just that the tape is capable of HOLDING 4 tracks… if you RECORDED 4 tracks.
32 kHz and 12 bit are the same setting in DV.
48 kHz and 16 bit are the same setting in DV.There is no 32 KHz/16 bit format. Its not possible with DV audio.
———————-“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.Also read this link:

It contains more “sync-loss” info.
