4.10 VIRTUAL INPUTS
Virtual Input buttons sit innocuously on TriCaster’s Switcher rows just like other video inputs, but
in fact they possess very powerful features. They can be likened to the M/E (Mix/Effect) rows of
a traditional video switcher, in that they permit a composition to be prepared from multiple
sources. In addition to the two sources just considered (
Inputs A and B ), Virtual Inputs provide
an integrated Overlay channel, as well.
COMPOSING INPUTS A AND B 4.10.1
When we ended the previous section, the simple ‘weather map’ setup (Figure 72) we created
was on
Program Out . Again, remember that LiveMatte is already enabled for the greenscreen
shot from our previous exercise.
We can use a few of the unique features of Virtual Inputs to dress up our production. For
example, we might want to transpose the greenscreen talent shot to one side, placing it off-
center in the result.

(Figure 76) for Input A.
