  1. Since NTSC VHS resolution is 300x360 and it's interlaced, wouldn't capturing an AVI at 300x720, then de-interlacing, be best? (I keep reading about capturing at 352x240, 352x480, or 720x480.) Wouldn't 300x720 at 29.97fps be the "perfect" initial capture for NTSC VHS to preserve all of the video with the least performance/space cost?

    Thanks a ton,

    If NTSC use 525 horizontal lines and some are used for frame sync and other information a value of 480 makes sense. But 360 is really something strange.

  3. I'd love to know where you got the 360 ??, the equivelant res is 480 (240 scanlines per field). Set the horizontal at your target res. Thus NTSC would ideally be 352x480, then deinterlace and re-size to 352x240.

  4. 352x240 and 352x480 are compromises. 720x480 or 704x480 would be best.
    If you can use VirtualDub to do your capture, try capping at 352x480 and enable the virtical reduction. That will resize it to 352x240 on the fly as you capture it. It also helps reduce noise and interlace effects. It's a pretty good compromise between quality and disk space, but if you want perfect, cap at the highest res your hardware will allow and downsample it later.

  5. This is always hotly contested. Make sure (for NTSC) that your vertical is 480. After that I'm not even going to start the horizontal res argument again, but bascially do whatever you want as long as you don't drop frames.
