| mattenee is a chromakeyer, this is an essential part of a virtual set. While the virtual set is the background, mattenee is what actually removes the colored background from the source and inserts the virtual set image. The way it works is that mattenee looks for the most chrominant color, either blue or green in most cases, and removes it. mattenee then tries to compensate for keying artifacts like chroma spill and compression. |
