And in general, a "feather mask" with "shrink" and "grow" options would be useful for a lot of plugins and general mask work. However, I have no clue how to code this :-( But if you want to do so, I suggest you make it a separate plugin, it'll benefit everybody.

Spill threshold is a hue threshold: the colors that have a similar hue (+/- the threshold) to the key color are desaturated. The amount of desaturation is controled by "spill amount" : the higher spill amount is, the more you desaturate the color. I suggest you start with spill amount to the max, spill threshold to the min. slowly increase the threshold: the spill areas will become grey. Once you've selected all the spill areas, reduce spill amount to match the rest of the scene. As far as the white/black pixels are concerned, please send me the test footage/cinelerra project file and a screen capture so I can have a look. I've tested it in all alpha modes (YUVA8, RGBA8 and RGBAFloat). If you are using a non-alpha mode, let me know.
