Color Selection

This is the FilterFrei0r-select0r filter

This is color based alpha selection. IE this offers you a blue screen/green screen/chroma-keying effect.

Selection Subspace options are: RGB, ABI and HCI

Subspace Shape options are: Box, Ellipsoid, Diamond

Edge Mode Options are: Hard, Fat, Normal, Skinny, Slope

Operation options are: Write On Clear, Max, Min, Add and Subtract. This defines how to deal with an existing alpha channel in the clip. See Alpha Shapes for the meanings of these operations.
