Need Help Brainstorming VHS-Digital Transfer Problems
 I am working with a third party to convert VHS tapes onto DVD. At home, I only use the copyguard removal tool when the video won't  transfer  (note: most of the tapes are not protected, just really crappy quality). The reason is that when the tool is turned on, it caused horizontal "tearing" or wavy lines (think really bad Twilight Zone effect) on all clips.  So I use it only sparingly when I have no other choice

The third party is using a Time Based Corrector which also serves as  copyguard remover (if needed). We're getting the same problem - even if a tape has no copyguard on it, if the tool is turned on, it causes wavy lines. There is no way for him to capture without it (his setup is fixed).  

I'd love another set of eyes on the results to decide whether to proceed. And of course any suggestions.


  

edited: based on feedback, I tried adding a different TBC/clarifier (Panasonic DMR-ES10), inserting it before the Canopus capture card. This stabilized the image but introduced  a red/purple color shift across the clips. Again, this is not copy-protected tape - just really bad source.

What this tells me is this

1.An automated approach may not be feasible - we either live with jagged lines through all the vids or red/purple color shift through all the vids. Or we stick with the labor intensive method - run the video until it stops, mark the location, proceed and then return to decrypt the "bad vid" at the end.

2. I need to try different TBC/copy guard removers before confirming #1. There are two more - one is the Sima (on loan) and the other is the 
ATV-8710 that I will have to buy.  This second one does not have as good track record removing the wavy lines as the Panasonic DMR-ES10. One online reviews say that it handles wavy lines very much like the TBC that the third party uses (DataVideo)

3. If #1 turns out to be correct, I may not be able to use a third party because all they can do is push a record button and cannot make adjustments.



Links: all copyguard removal tools degrade the picture. So using them for all source may be counter-productive.

Digital copyguard removal tool recs

stand alone DVD recorders may be better for bad quality video

but if you need to get an external TBC the ATV-8710 might work
