When outputting to tape do you see a difference between composite & s-video? VC>> To my eyes, no. I've captured/output from/to several VHS and S-VHS recorders (both composite and S-video), from a LCD (s-video and composite), LD (composite only), and several Hi-8 (s-video and composite). Could I capture using composite, output using s-video and still get a good quality? VC>> That will not affect the quality. At this level of desktop video resolution (about VHS level) that the current board and system can handle (around 1M bytes/sec non-compressed data), the important things are the quality of the source, the tape, the recorder, and the combination of the capture board and the storage sub-system. The type of connectors doesn't matter that much. Capturing video alone (reducing the amount of the data to be captured), capture audio, then sync them together using a software like Media Studio will help to improve the quality of the captured video clips. Or should I go s-video for both? VC>> If you could, why not? I mean, just use the best of the ones that are available. The priority is like this: component, s-video (Y/C), and composite. Without going into details (which I don't understand either), the seperation of color signals and brightness signal help because the color signals are burst signals attached to (carried by) the brightness (black and white) signal. They uses phase angle (to the color sync signal at the head of each scan line) to determine the color of each color dot. In nature, they disturb with each other. So, seperate them is good, seperate the color and brightness is especially helpful. However, the transmission rate of each color signal are not the same, so you will need to add delay to adjust the color shift of separated RBG signal lines after long transmission distance. blah. blah. blah.
