The answer is probably no, unless the SCART socket on your VCR is labeled specifically as "S-VIDEO". The fact that SCART connector has S-Video pins does not guarantee that your VCR provides ...

Does using an S-Video output via a SCART connector improve the output quality of a VCR?
Yes, using the S-Video output of the SCART breakout will give you better quality than if you use the composite output of the same breakout. (You can get even better quality if you use a different ...

Vhs capture: 720x576 or less?
I think you want to capture at 640x480. VHS uses interlaced video, so the recorded content provides half the lines every 1/30th of a second. The effective resolution is horribly low, 352x240.
