Filter to show Cr and Cb separately?

[PaulJBis]

Hi all:

A friend of mine, a professional video editor, has just discovered VirtualDub and is using it for some image processing stuff. He asked me whether there's any filter that can display the two color channels Cr and Cb (or R-Y and B-Y) separately, just like ViewFields does for fields. I don't know offhand if such a thing exists, since I've never needed it, and I have searched a bit and found nothing. So... does it exist?

[Si]

I wrote a simple filter a long long time before Viewfields that displays the Y,U and V Channels (Extract/Combine YUV) (http://www.geocities.com/siwalters_uk/fnews.html)

AFAIK no-one has ever used it but it might prove useful (or even work ;) )

Avisynth is really the way to go as its works natively in YUV.

regards
Simon
