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.
