8.2.6 LIVEMATTE
The second tab in the Input Configuration panels is where TriCaster’s powerful
realtime keying system for live production, LiveMatte, is configured. Keying is a
popular and powerful method of compositing multiple images, whether photos,
video clips or live camera streams.

The process involves eliminating a portion of the image (effectively cutting a digital
‘keyhole’ in it) to reveal a user-defined background scene. It also plays an important
role in the workflow of LiveSet, TriCaster’s powerful virtual set technology.
LiveMatte’s controls are deceptively simple, making a great deal of complex digital
manipulations easy to use. Even so, much can be said about getting the best results.
For that reason we’ve devoted a whole chapter in this manual to discussing it –
please see Chapter 13, LiveMatte .
Hint: When LiveMatte, Proc Amp, or Crop settings are active for a source, bright green,
blue and yellow indicators are lit under its monitor.
