maybe not? Somehow I get the idea that a 699 pixel capture could never gain back the 21 pixels.
I'm not sure we're quite on the same page, but I think it's my poor wording. I'll try again, a different approach...The resulting avi from a capture that is set to 720x480 will always be 720 pixels wide. Now, what if the capture card and/or its driver is so screwed-up up that it's taking the VHS picture and making it only 100 pixels wide for your "video capture area" width within the full capture frame? Each frame is still 720 wide in the end, but within that 720 width you have 620 pixels of pure black and 100 pixels of really squeezed video from your VHS.
A capture card is capable of putting the wrong width/height image from the VHS into your 720x480 avi, and BTTool seems to be a way to fix that, that's what I'm trying to say. Obviously, a picture area that is only 100 pixels wide (within the full 720 pixels image) is erroneous, but what if it's 6 pixels off from what it's supposed to be rather than hundreds of pixels off? You might not notice a 6 pixels squeeze with your eye, but it's still wrong and it's good to correct it at the capture stage if possible. That's what the doom9 page I posted a link to was taking about. I'm just piecemeal regurgitating from that page, and I bow to its expertise so feel free to go back there for more straight info.
I believe the ideal capture area picture width from VHS is 702, leaving 18 pixels of black to the left and/or right of that 702 to fill out your 720 width. You and I are more worried about the top of our captures because it looks like there might be cropping happening at the top of the frame. At least that's what I'm worried about, and want to correct. Still have too much stuff going on right now though
