Vid Cap Noise

Using the HDV capture tool, I've captured HD Video (via firewire) from Canon XHA1. The footage is a well-lit green screen behind an interview subject. The tape WAS NOT SHOT with this camera, but in the camera's viewfinder and monitor the image looks glorious, sharp and clean. However in the capture window AND the resulting files, there's a lot of image noise (manifesting itself as a random pattern superimposed on the picture, visible as a random flicker of "dots" or "snow")

In capturing another piece of video (a music performance in a dimly lit club, shot ON the XHA1) this noise is not present. The camera is NOT set to HD downconvert, and I'm using the SONY HDV capture tool... ideas?

Vegas Pro 11 (because 12 is terribly unreliable thus far, many crashes, many freezes)

Try HDVSplit which is a free utility. HDV capture in Vegas was never good and had always an issue with splitting the scenes properly but I never had an issue with the video quality.

Your description sounds like tracking issue in the camera playback of the tape which would be entirely suspected because of the tape source. Could be the origin camera's fault, or the fault of the XHA-1.

To better pinpoint the source of the noisy picture - use your analog component output of the camera to go directly to a large flat widescreen TV panel. This will give you the ultimate vision of the tape's integrity in playback over the path of the XHA-1 heads and guides. The on-camera monitor is worthless for fine degree of viewing.
