Resize color matte after creation

[#1]

I've already created a color matte, and I want to change its size (in pixels) rather than scaling & cropping it. Is there a way to modify the original size that I set when I created it?

don't think so, but why do you want to do this?  I just scaled a color matte up to over 3000% and don't see any degradation in the image.

I couldn't quite figure out the right size to set it to & was doing it by trial and error... I had the aspect ratio wrong originally. So if I scale it up, then I have to crop it as well. It was easier to start over because I couldn't figure out how to edit the original values

You cannot edit the original values but you can replace clip from bin with a color matte with the correct values.
