The term Matte refers to a black and white representation defining the transparent (background) and opaque (foreground) parts of an image during compositing. 

Portions of the matte that are grey are treated as semi-transparent, which is very useful in progressively smoothing edges between foreground source material and inserted background imagery.


TriCaster’s supplies a digital version of this traditional tool.  The controls under the Matte label, as you would expect, allow you to define and adjust the matte for the corresponding video input.
