Does anyone have any suggestions on what could be causing the video from any of my s-vhs decks to look like this?
The whole top of the video is distorted and shakes side to side.
Any other video source through my BOB is normal.

Make sure you don't have two sources connected to the same input on Bob.

I believe this is called "Skewing", but I am not a technician.
I think it is a result of your camera or VCR (probably the camera) needing a cleaning/adjustment.
Immediate solution would be to try to play the tape from the same machine/camera that it was recorded on. I think that will solve the problem.

In advanced proc amp settings, try:
AGC Freeze - Not Frozen
Chroma Trap - Enabled
Horizontal Tracking Loop Frequency Select - VCR or TV (Chroma trap will have the largest effect when capturing from VHS.)

I just ran into this same problem (T3), and knew I had seen this thread somewhere in the past. Setting "Horizontal Tracking Loop Frequency" to "Very Fast" cleaned it right up.

Thanks Paul! :D

I've got this same problem with [2] and none of these fixes are fixing it! Any other suggestions?

Setting "Horizontal Tracking Loop Frequency" to "Very Fast" works very well here (used it just the other day). Is your Proc Amp enabled (not bypassed) and looking at the right input?

This probably only works for analog input from a VCR. I don't think it will clean up an already bad capture, or something that was poorly dubbed "saving" the skew...

I've seen this problem on another NLE (similar to VT with internal software TBC) and the solution was to run it through an external TBC before capture. You may need to lock it up to the VT, but that is a simple procedure by sending one of the VT's outputs to the TBC's genlock in. Make sure you terminate as needed.

Thanks, Jim.

Not having access to any other hardware, I sent the source to my camcorder, then back to the VT. It worked fine. Stupid VHS format. :rolleyes:

Looks like you could use a little Bob's One Touch...

Bob's One Touch? I'm almost afraid to ask...:)

Bob Tasa's plug in.

Awesome great stuff.

I was referring to your color balance. It looks way too blue. Therre are many apps that can color correct a bad white balance and even the CC controls within VTEdit can help, but Bob's One touch makes it a very simple with good results right in VT.

If you have lots of footage to CC, you may want to process it render to a new file and dump the old, or even 're-capture' it from VTEdit through the switcher to a new file.
