Use the MasterK node to access the Master Keyer in order to create a complete key by first extracting colours to generate a matte, and then refining the result. The MasterK node can be added anywhere in the Modular Keyer pipeline.
The Modular Keyer allows you to bypass the MasterK node by designating either its front, back, matte, or key-in clip input as the result.
The MasterK node's operations are bypassed. The clip selected in the Bypass box passes to the next node(s).
The menu in the MasterK node is otherwise identical to the Master Keyer menu available from the Keyer node and from the Keyer module. See Keyer.
