Uncompressed Capture

Hi,
Does anyone know if it is possible to Capture a DV-clip absolutely uncompressed into Vegas ?
The best Average Data Rate I get is 3,44mb/sec (DV-PAL), I would like it to be something like (720X480) approx 0,5mb? X 25 pictures/sec =12-15mb/sec.

If anyone now if that is possible in Vegas please let me know how to do it.

Thank you,

Thomas.

If the source material your are capturing was shot on DV, there's no point in capturing it as uncompressed. The camera has already done the compression to 5:1 (the DV format's compression rate), so all you'd be doing is needlessly decompressing the DV frames and filling up your hard drive.

Capturing a DV clip over 1394 is a bit-for-bit data copy with no additional compression added during the capture process, so there's ZERO quality loss.

Just about the only way to do this is to capture the DV clip normally, place it on the timeline, then render it to an uncompressed .avi format. There's not much reason to do this though. The video signal is compressed to DV by the camera, not by the capturing process. So what you'd end up with is an uncompressed version of an already compressed video.

Probably the only reasons to do this would be if you need an alpha channel or if you need to export to some other software that won't open DV files. It won't give you any increase in quality.
