Choke chromakey from 3 sources Takes three 4-plane char matrix and does an interchangeable choke chromakey between the three sources. Any of the three input matrices can be designated as the key image (from which the image mask is created), the target image (which the mask is overlaid onto), or the mask image (which is placed on top of the target in the shape of the key).

A matrix received in the key inlet is used to build the shape of mask image Mask matrix inlet The inlet number for the mask matrix (default = 2)
A matrix received in the mask inlet is shaped by the key image and occludes the target image Chomakeying mode Chomakeying mode (default = 0 (key entire cells))

Red tolerance level The red tolerance level for the chroma key (default = 0.) Target matrix inlet The inlet number for the target matrix (default = 1)
A matrix received in the target inlet is placed behind the mask image The jit.keyscreen object takes a color and a tolerance range for the keying. It can work by cell or by plane (set via the mode attribute).
