Random Cuts During Capture

I edit HDV format on both my laptop and PC with a Canon XH-A1. I never have any issues besides the rendering time but in the past months for some reason, when I capture my content there seems to be random cut that are done in the file which gives me a fragmented file in 4 pieces instead of just one.

I want threw my computer to try and see what could be doing this and I haven't found anything different from when it wasn't doing this. I checked my cassettes to see if they were dirty in anyway and they weren't. The playback on my camera was clean. I got my camera cleaned as well and it still appears to cut in the capture process.

While capturing make sure you are not using scene detection. It should be an option in your capture interface.

This happens to me too on occasion. The splits are random, there are no dropped frames reported, and recapturing the tape will split in totally different random points or sometimes not at all. Very odd.

Every time it has happened to me, I was stressing the CPU doing other things. Even though the CPU doesn't show 100%, it may be enough to throw the timing off on capture to somehow make the capture program think there was a timecode break.

I once tried capturing while I was rendering with another instance of Vegas. Don't think I'll try that again. I got what should have been a 1-hour continuous clip split up into about 20 segments. Recaptured after the render completed, and it was clean.

Very strange. I'll capture while i've got 2, 3, or even more renders going simultaneously, browsing the web, watching a video, chatting, and a dozen other applications running. Never have a problem, ever.

Always go into Windows process manager and set the priority of the capture program to above normal. This way every other program on the system gracefully allows VidCap all the cpu cycles it needs, when it needs them.
