ScreenReplace v1.0

ScreenReplace is an all-in-one additive keyer node that can be great for extracting alot of detail very quickly. The core of ScreenReplace is basically a rebuild of the IBK Gizmo keyer in nuke (matches IBK and Keylight with identical settings) with additional options and more control. These options include more despill parameters, Core Spill vs matte spill, and preprocessing log settings. Due to the node having a BG input and internal over operation, mathematically in certain scenarios the ScreenReplace can produce far less artifacts and nasty edges than what IBK and keylight can do. Also, its rebuilt with basic nuke nodes and still allows the artist to dive into the group and add aditional nodes and treatments such as edge extends and transforms making the tool less of a 'black box'. I generally use this tool for edge detail but at times it works well enough to be used for the entire key.
