As I mentioned, I recorded a project on Sunday and captured one camera to my laptop via Vegas. I mentioned that the capture speed was out by around 30 seconds in an hour when compared to my other cameras.

Now it appears the capture speed also varied throughout the recording, because after sync'ing it start and finish, I have found (after multicam editing)a clip about 10 mins in that is out of sync by15 frames.

Has anyone come across this?

If you were capturing to the internal drive of the laptop (the system drive) this COULD be the problem. With the app running and capturing to the single drive the might be a challenge with that.
If you were capturing to a seperate drive then perhaps a bad connection, bad drive or a slow drive. Maybe not working to its stated speed.
could be a lot of things.

HOW did you capture it? How was the compter connected to the camera?

I've capture DV straight to the computer with zero issues. If you captured some other way, the capture method may have played into the problem you're having.

I was capturing direct from the camera via firewire cable, to the laptop"s internal drive, using Vegas 7 > Video capture 6.

I was able to correct the clip placement on the multicam track by moving it the 15 frames then resizing at both ends.

It will be interesting to see what the other clips from that camera are like.

I see now, given the time it takes to copy a file of this size from the laptop, that it would be better to capture to an external drive, which could simply be unplugged and plugged into my main computer.
