The Look Ahead Preview is versatile and powerful. Instead of showing just one video source (the Preview
row selection), it displays the composite result of a Take operation applied to all currently delegated video
layers (see the sub-heading Transition Delegates in Section 9.4.2).
Selecting the BKGD delegate tells TriCaster you intend the next transition to swap the Program and
Preview layers. The Preview monitor will show the Preview row selection as its background.
When the BKGD delegate is not active, the BKGD layer will not change during a transition.
Consequently, in this case the Preview and Program monitors share identical backgrounds.
Delegated DSK layers are shown above the background on Preview according to their current state.
That is, if a delegated DSK layer is currently displayed on Program output it does not appear on
Preview – since the next transition would remove it.
In other words, ‘what you see is what you will get’ – after performing the next Take or Auto operation as
currently configured. This lets you set up the next shot, check its composition (including titles and overlay
positioning), and switch to it with sublime confidence.

ROGRAM
As mentioned earlier, TriCaster’s monitor viewports can also be assigned to display the output of TriCaster’s
M/Es. Among other things, this means you can freely assign a monitor as a secondary ‘program output
monitor’ in cases where you are using an M/E in Mix mode to supply an auxiliary program mix for
independent display. Viewports can be assigned to specific M/Es, or follow the delegate status (Outputs >
M/E Follow).
FIGURE 119
Complementing this feature, TriCaster provides Look Ahead Preview monitoring capability for M/Es as well
(Figure 119). The Viewport Options menu group Outputs lists a special M/E Preview option for this purpose.
Hint: All viewports assigned as M/E Previews show output from the same M/E. Making an M/E tab selection
updates all viewports when Tabs Follow all Delegates is enabled.
Just like the main Look Ahead Preview, the M/E Preview respects Delegate selections made in the Transition
section of the assigned M/E, showing you the display that will result from the currently configured (M/E)
Take/Auto operation.
