Hello everyone.

Today I was doing some chroma-key exercise to remove a green screen and I was getting mad at suppressing the spill over the talent through the key spill mop up effect.
I think the edge inward/outward mask types and the two checkbox to show the alpha channel and the mask to alpha are very nice but the whole effect has little impact and it is fairly difficult to tune.
That is, it seems that it is used for very very very fine tuning.
It was not really working for me...

Then I gave a shot to the despill effect and BOOM!
It worked like a charm. All I had to to was to set the Set Green Scale parameter to -0.4 and to increase a bit the Spillmax Mix parameter and I got gorgeous results.
I also noticed that differently from the key spill mop up effect here the parameters are VERY sensitive to change.
When it turns into green screen I found a lot of references to the key spill mop up stuff but I haven't never found any reference on the despill effect.

Well, I just wanted to share, maybe someone could find it useful!
