What is s-video vcr?

S-video (separate video) VCR is a type of videocassette recorder that uses a round, four-pin connector to transmit a higher quality video signal than composite video. S-video VCRs were popular in the 1990s and early 2000s and were commonly used for recording and playing VHS tapes. They work by separating the video signal into separate luminance (black and white) and chrominance (color) components, resulting in sharper and clearer video quality compared to composite video. S-video VCRs have been largely replaced by digital video recorders and streaming services, but some older devices and equipment still use S-video connections.
