Y/C delay correction filter?

Is there a filter to correct for Y/C delay after an S-video capture to Virtualdub using Lagarith? I read that "flaxen" can do it, but flaxen is nowhere to be found.

Thanks,
Steve

this avisynth script can do it :

Code:

avisource() # for interlaced source

assumetff()

separatefields()

A=Last

B=A.Greyscale()

Overlay(B,A,X=0,Y=-2,Mode="Chroma") # change values of X and Y according to your needs (Y=-2 is fine for vhs generally)

weave()

The ChromaShiftSP is another simple option. As noted in the previous reply, if the source is interlaced you need to separate into fields before shifting chroma if altering in the y direction:

Code:

separatefields()

ChromaShiftSP(Y=-2)

weave()

flaXen is in the pre-loaded VirtualDub download on this site.
But I'd probably still opt for Avisynth when available.

ChromaShift V2.2.0 from JPSDR which is included in his filtres packet. Works in YUV color space.

Unzip and then put the Filtres_JPSDR.vdf file in your Virtual Dub plugin folder.

Thanks Guys! Now I need to figure AviSynth and Virtualdub out.
