What is TBC ?

[joelson]

Hi!

I just have a tape that I'm trying to capture. However, in some parts, the image shakes, seems like a ghost.

I have read some posts telling that I should use a TBC (Time Base Correction). But what is a TBC??

Is it an equipment? Or a special cable? What??

And how much does it cost, approximately?

From the <== glossary on the left

Time Base Corrector
A hardware device used to remove or mask variations in the video synchronizing signals, which can result in "skewing" and other distortions in the video image generated by unavoidable mechanical inaccuracies in helical scan recorders. This is accomplished by automatically delaying the video signal so that each line starts at the proper time. In capturing a TBC is used to 'clean up' analog tape problems and may assist in the capture of old VHS tapes when used betwee a VCR and capture card. Hardware TBCs can be expensive.
