The Background Preset section allows you to easily recall frequently used background

5.2.6 LIVEMATTE
TriCaster’s LiveMatte keying system removes a specified color range – the ‘key’ color – and a
tolerance factor on either side of it from one video or image source, replacing it with material
from another source.

The best known application for chromakeying is the ubiquitous TV weather broadcast. In the
studio, the presenter stands in front of a green screen. The chromakey system replaces the
green (key) color with computer graphics.
TriCaster’s LiveMatte provides a very high quality yet easy to use keying system. To begin our
exploration of LiveMatte’s basic operations, we will select some suitable source material.
Hint: You may not be all set up with a greenscreen studio, so NewTek has supplied some Demo
clips for this purpose, already installed on your TriCaster.
LIVEMATTE AND THE SWITCHER
When a LiveMatte-enabled source is selected on the Switcher’s Live row, imagery from the
Effects row source shows through wherever the key color is removed.
