VHS-C horizontal lines/distortion, what's wrong?
 
Hello,

I have been successfully importing VHS & VHS C tapes for family archival purposes. I am struggling with two tapes.

The physical condition of the cassette is good and the tape looks clean, non-sticky, without creases or shedding. These tapes were stored with a member of my family in the same box with the same conditions as the rest of the tapes.

While most import perfectly as I would like them, these tapes have horizontal lines across the entire image, what can I do to fix it?

Please see this example I have uploaded to YouTube so that you can see what is happening. https://youtu.be/Qk1fJ5n6UHY

I really appreciate your help in answering this.

It looks a lot like the effect you get when playing a Super-VHS recording in a normal VHS player. Even if it's not a SVHS cassette later models of SVHS VCRs and camcorders could record in Super-VHS at slightly reduced quality on normal VHS cassettes (called SVHS-ET). In that case you would need a SVHS VCR (or camcorder) to play them back properly. Some late 90s/early 2000s standard VHS VCRs could play back SVHS at reduced quality, labelled as SQPB, but you need a proper SVHS VCR to get the full quality out of SVHS recordings.

Black lines like this can be a result of other things like worn heads or certain other faults with a playback or recording VCR. That seems less likely though since given that you state that many recordings play back fine, and it's usually not quite this severe.

Certainly a S-VHS tape or S-VHS ET, The black stripes are clipping of the luma bandwidth since VHS has a limited bandwidth.
