Capture cable quality vs. length

Hi,

I usually capture video from my camera using a 3ft braid-screened firewire cable, and everything is OK.

The other day I used a different firewire cable, this one was not braided, and was 10ft long. The results were not good. Whenever someone moved, there was a sine-wave type ripple around their body - difficult to describe properly, but that is what I saw when I played the captured video back. There were no dropped frames.

Would this problem be caused by the overall non-braided cable quality, or the longer cable run, or a combination of both?

Thanks,

Bryan.

It shouldn't make a difference.

Video captured over FireWire from a tape-based camcorder is digital -- so you either get it or you don't. It's not possible to get reduced quality digital video data.

Thanks Steve, of course, I should have realized that - one of those things I use all of the time without really thinking about it.

Anyhoo, I found the problem, seems that the Project Video Properties was set to NTSC Standard, instead of NTSC DV. Once I changed that, it all seemed to go OK.

Cheers,

Bryan.
