LOOK AHEAD PREVIEW
Let’s pause here to consider TriCaster’s Look Ahead Preview monitor. Cast your eyes
over the Preview monitor, and consider how it relates to the state of the Transition
Delegate controls.
In Figure 60, the Preview monitor shows DSK 2 (assigned to Buffer 1) overlaid on the
current Preview row selection. The Look Ahead Preview monitor (or simply, Preview)
always shows us the composition that would result if a Take or Transition operation
was performed respecting the current transition delegate(s) –a look into the future,
if you will.
21. Hold down Ctrl on the keyboard again, and click the BKGD Delegate button
(de-selecting it).
Note that, after de-selecting the BKGD delegate button, the Preview monitor no
longer shows the Switcher’s Preview row selection. Instead, it shows DSK 1 over the
current Program row selection.
Why is that?
Since only the DSK 1 and DSK 2 delegate buttons are active, only those two video
layers will be affected by a main Take or Auto operation. In this state, the result of
an Auto operation will be as follows:
 DSK 2, currently seen on Program out, will be removed from view
 DSK 1 will be overlaid above Program instead.
 The BKGD layer – not being delegated – will not change in this case. Hence
Preview correctly depicts the outcome of a Take or Auto, just as we’ve
mentioned.
The Look Ahead Preview allows you to switch with real confidence; the Transition
delegate features provide flexible and convenient video layer management, and thus
enhanced control over your ultimate Program output composition.
