Sphere or cube keyer driven by a selection sample in position, color, or CIE-LCH space, with soft range, axis scale, invert, and gamma.
Swiss Keys builds an alpha from a sampled selection using a sphere or cube falloff. You choose the working space (position, color, or CIE-LCH), pick the input layer and output channel, and set blackpoint and whitepoint for the soft edge.
Optional log transform routes the signal through Cineon before the key. Axis scales stretch the sphere along x, y, and z; invert and gamma finish the matte. The result is copied onto the chosen output channel so you can drop it into a standard keying or isolation stack.
Use it when a simple luminance or chroma key is not enough and you need a controllable 3D-style key around a color or position sample inside the frame.
