I have a G-3 MT with the A/V card. I use Adobe Premiere 5.1 to capture analogue
video.

If I set Premiere to capture video at 640x480 at 29.97fps and save it directly to my
hard drive, Premiere complies and does same. As it's capturing the capture window
shows the video at 640x480 (like I expect).

When I the capture is completed and I am working with this video clip file in
Premiere, I can choose "Get Properties for..." that file and Premiere reports that
the image size is indeed 640 x480. However, Premiere also reports that the Frame
Size for the Video Block #1 of the same file is 320x240.

QuickTime Player reports something similar: a "Movie Size" of 640x480 but a "Video
Track Size" of 320x240.

My question is: at what size does the generic A/V capture card do its magic?
320x240, and then doubles the width and doubles the height when I request a 640x480
capture? or does it actually capture at 640x480?

If it *does* capture at 640x480 when asked, why would Premiere report ambiguous
information?

If it captures at 320x240, and I want to ultimately make a NTSC VideoCD (352x240),
then I guess there'd be no advantage to setting the capture to 640x480 if software
will eventually reduce it to 352x240, huh?
