Time Base Corrector

Travis Wheaton · December 28th, 2015, 03:15 AM

G'day,

A long shot, I know... but has any bright spark managed to create a filter that performs the role of the Time Based Corrector found in (good) video capture devices?

Thanks

There are several standard filters that duplicate the level adjustment features of a TBC. Color Correction, Brightness/Contrast and Proc Amp are a few. If you are looking for some sort of sync signal fix, that has to be present in your capture device if you are capturing from analog tape sources, VHS, 3/4, BetaSP.

Thank you for the reply, William.

The footage in question was captured on a Sharp Hi8 Viewcam, and then transferred to standard VHS (just directly, nothing special).

I've then digitised the VHS via a VCR, to handcam with analogue-digital pass-thru, into my iMac. I used a filter (AJW's Y/C) to fix the colour shift... Played with the 3-way colour corrector to fix the colours (but will try the proc amp filter now you mention it!)... and added a few filters to mask the horrible drone of cicadas..! But there's some bad distortion ie lines that are shaky...
