simple question here. let say i want to capture analog from vcr and render as mpeg-2

What do you mean cut in half?

sorry i dont mean cut in a half, the size caputure from vcr will be something like 320x240 and mpeg-2 is 720x480. so i want to know if vegas will resize it to fit the 720 screen or not.
thanks again

By default, Vegas will resize the video to fit in the frame as best as possible while still showing the entire image. If your source clip isn't the same shape as the frame then Vegas will resize it just enough for two of the edges to touch the edge of the frame leaving empty black borders on the other two edges.

thanks Chienworks for the quick reply.
if i caputre analog from my VCR, that means i will have the edges on the top and the bottom right?
something i dont get it here. let say if i capture from my VCR using AD converter(advc-100 for example), am i capturing 320x240 or 720x480 after the convertion?
thanks

Using that converter means you'll be capturing a DV stream and DV is a fixed format. For NTSC it's always 720x480. There will usually be a border around the image since analog video doesn't quite fill the frame. With VHS there is usually a narrow black border down the sides and a couple pixels worth of static across the top and bottom. This border is isually invisible outside the safe area of the television, but will be visible when captured.

FWIW, depending on your player compatibility and all, mpg2 can be full, half, quarter sized etc. - the DVD spec allows full & quarter I think. If you're captureing 320 x 240, it might be less of a stretch to size to quarter (352x240) then full frame. If your player handles it, *might* look better as well with hardware upsizing, but you'd have to test to be sure one way or another. Of course, easier to capture full size if you can,whichever hardware method you use.

Also IMO better off using V/dub for the crop/resize if speed rendering is a concern, then import the rendered avi into Vegas.
