Does using an S-Video output via a SCART connector improve the output quality of a VCR? This answer reports that in order not to lose quality when digitizing VHS one should use an S-Video cable.

My VCR is a Sharp VC-M401SM and does not have any S-Video output nor a composite output. Instead it has a scart video/audio line.

Question: If I use an adaptor like the following together with an S-Video cable can I obtain a better quality than using the same adapter with a composite cable? Why? Does the answer depend on the tape quality (VHS or S-VHS)?
The answer is probably no, unless the SCART socket on your VCR is labeled specifically as &quot;S-VIDEO&quot;. The fact that SCART connector has S-Video pins does not guarantee that your VCR provides S-Video signal to these pins. A low-end model will simply transmit a composite signal over the luminance S-Video pin and nothing over the chrominance pin.
Even my DVD player having both S-Video and SCART sockets doesn't provide S-Video signal over SCART. Only component RGB.
