Matte
Matte – An operational image or signal carrying only transparency information and intended to overlay and/or control a conventional image or image signal. a) Without shine or gloss. Relatively unreflective of light. Removal of a portion of a TV picture and replacement of it with another picture. b) A solid color, adjustable in hue, luminance, and saturation. Matte is used to fill areas of keys and borders. Ampex switchers generate many internal matte signal keys. c) A film term used to describe the film effect analogous to a key. Sometimes this definition is carried over into video and used to describe a video key. d) A black and white high contrast image that suppresses or cuts a hole in the background picture to allow the picture the matte was made from to seamlessly fit in the hole.
