S-Video Horizontal Distortion

[jeby1980]

Hi there, I finally ran across a JVC S-Vhs player (HR-S3910U) that I thought I would try out since I hear the results are so much better than composite video.

After running through the same capturing setup (except for the player and connection) and post capture processing script in avisynth+ (deinterlaced, recolored, and degrained), I'd say the s-video player results are worse. Any vertical linework is wavy. I attached two screenshots, one from the s-video version and the other from composite video. As you can see from the dancer's leg, the s-video version is much more distorted.

Would you suspect that this is maybe a player with bad heads if I can get nice output from the composite video setup? note, my composite player does not have a built in tbc

Post a video sample of the untouched captures, not processed images (btw no tbc in jvc vcr as well)

That JVC S-VHS unit doesn't either. It's the low-end S-VHS model, mostly good for recording.

Check your cable quality. Used a cheap thin svideo cable and got checkerboard patterns and odd sparadic distortion. Got a thick properly shielded cable and it all went away minus what the actual source damage introduced.

But also avoid fat-header cables, as those too often damage the VCR I/O ports.

1. Did you disconnect the composite cable when doing the S-video capture?

2. Are your two images in post #1 from the same VCR, one using composite and the other S-video, or, are they from two different VCRs? If the first one is from your new JVC and the second from your old VCR, then we are not really comparing S-video to composite. We are instead comparing the quality of two different VCRs. That is a totally different set of questions and answers to what is posted here.

3. The first image definitely exhibits time base errors.
