11 LIVEMATTE & CROP
Although its controls are 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 LiveMatte can play an important role in your live
productions.
Likewise, Crop can be invaluable for removing unwanted items or
isolating part of the video scene.
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.
