remove chroma from a digital video and add new color to the luma

[rudolf016]

Hi,

I captured videos from old vhs tapes but the picture is jittery.
I have a VCR with a TBC that removes the jitter completely but because the VCR is old the TBC changes the color of the video when it's on.

I thought I could capture every video first with TBC on to capture a video with good jitter free luma and then capture the video again with the TBC off to capture the video with good color.

So is there a way to take the color of a digital capture and change it with an other video so that I can put the good luma and good chroma together? The captures are in Lagarith but I could convert it to any other lossless codec. And I'm using virtualdub and virtualdubmod but if the task is not possible to do with these to editing softwares I would still be curious to know if I can do it with any other software.

Thanks for any help.

use greyscale() for clip1's luma and mergechroma() from clip2

No need for Greyscale().
MergeChroma(clip1, clip2) is enough, taking luma from clip1 and chroma from clip2.
