Picture ok on TV, jumpy on capture

[Nick Pappas]

I have been trying to figure out a solution to this, and am hoping someone here can help out (or dash my hopes for good).
I have 3 SVHS tapes that I am trying to encode. They look great when viewed on the TV, but "jump" and "twitch" when viewed on the computer.

The whole picture may jerk, or the top portion may just twitch slightly -- in both cases it is captured in all it wonderful annoying glory.

Can anyone point out some tips on preventing this "noise" from getting through? While I understand why it is possible to look ok on the TV and not on the capture, I don't know if I can fix it -- I am hoping someone here does.

I have tried 2 different SVHS VCRs, and also tried dubbing to a VHS then capturing -- the same issue everytime. I also have other SVHS tapes that work great... so I am confident that it is just these three.

Thanks for any help!

It sounds like some degradation in the tape may have ocurred. When this happens you sometimes end up with weak synch pulses that the TV can read but will cause a dropped frame or field problems when they are captured.

I feed such "trouble" tapes though a video processor (PROCAMP). Mine is an Elite Video BVP-4+ (~$750 USD) but SIMA makes their SIMA Color Corrector that can also tame errant synch pulses and colorburst signals. The SIMA SCC runs about $130 USD.

Do you have any links, or possible store names I might be able to visit for such a magical box?

Many thanks!!
