View Full Version : changing a range of color for another

09 September 2004, 03:21 PM
hey guys,

Can someone explain me how to change one color to another with color corrector seems that I can supress a color quite easily, but I don't find a way to replace that color i supress with another one..

I don't want to use chroma keys..would like to do it just with the color corrector.;

thanks for any help

Not possible with just the color corrector. You need to either chroma key something to provide a bitmap mask to a color correct applying a hue shift, or some other way to apply a mask. I assume you want to do this procedurally and not via rotoscope?

One might try to supress the color you are trying to change with one CC node, and then use a boolean set to diference as a second branch, use this to generate a mask, and then apply a second CC node to actually change the hue.
