14 LIVEMATTE
Although its user interface is deceptively simple, LiveMatte
represents NewTek’s newest and most powerful chromakeying
technology, and is capable of very high quality results.
Whether you use it alone or in conjunction with TriCaster’s Overlay
or LiveSet features, you will find it can play an important role in
your live productions.
As we mentioned earlier, chromakeying – or simply “keying” – is used to combine images by
eliminating a portion of a foreground image (effectively cutting a digital ‘keyhole’ in it) to reveal a
different background. TriCaster also relies on this method to insert talent seamlessly into virtual
sets via LiveSet.

LiveMatte controls and are located in the Input Configuration panels for every Switcher source.
To access them, click the Configure button (gear) that appears above an ISO monitor in the All
Monitors tab. The second tab in the (source) Configuration panel is labeled LiveMatte .
Hint: Clicking Configure for a monitor in the Switcher Monitors tab likewise opens the Input
Configuration panel for the corresponding Switcher row source.
