Also, ALWAYS RESIZE *AFTER* DEINTERLACING. If you do it yourself, you get better results. This is because some drivers actually only support 720x480 and resize themselves, usually with a lower-quality algorithm. Shouldn't I capture in 640x480?Ī: No, you should capture at 720x480 and then resize to 640x480 after deinterlacing. Q: 720x480 doesn't always look right in players. In the description he says you can resize it after you capture it: "The typical digital representation of NTSC analog video is this slightly strange aspect ratio of 720x480" I've been capturing at 720x480 based on the instructions in this tutorial video: If your capture card can't capture in resolutions like 352x480 or 512x384, use VirtualDub to do it by choosing the option "set custom format" under the "video" menu. At last, if you want to make a VCD compliant video stream (which MUST be 352x240 at 29.967fps), capture at 352x480 at 29.967fps (this way you get both fields), and then resize it to 352x240 using VirtualDub with the "precise bicubic" filter on. Now, if you don't need such perfection, or your system can't keep that up, use 512x384 at 29.967 and the result will look quite as good as 640x480. However, Some would say that such a high resolution for a VHS source is a waste of time and space, but I suggest: if you like things perfect, try that resolution. You can do that with software like Adobe Premiere or VirtualDub. If you want your capture to look just like the VHS source (unfortunately it can't look any better), capture at 640x480 at 29.967fps, and then DEINTERLACE it.
