11 LIVEMATTE & CROP
Although its controls are deceptively simple, TriCaster’s LiveMatte™
is a very powerful chromakeying technology, capable of extremely
high quality results.
Whether uses alone or in conjunction with TriCaster’s Overlay or
LiveSet features, you will find LiveMatte 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 are located in the Input Configuration panels for every Switcher source. To
access them, click the Configure button (gear) that appears above an onscreen monitor in the All
Monitors tab. The second tab in the (source) Configuration panel is labeled LiveMatte & Crop.
