* Adherents of the ‘multiverse’
concept insist we mention that
the Look Ahead Preview shows
only one among many possible
futures.
NewTek takes no position on
parallel universes, and has no
comment on plans for a multi-
dimensional preview.

What the Look Ahead Preview monitor (or simply, Preview)
is really showing us is the composition that will result if we
perform a
Take or Transition operation right now – a look
into the future*, if you will.
17. Hold down Ctrl on the keyboard again, and click the
BKGD Delegate button (de-selecting it).
Note that, when you do this, the Preview monitor no longer
shows the Switcher’s Preview row selection. Why is that?
Having de-selected the BKGD delegate button, only the DSK
1 and DSK 2 buttons remain lit. Thus only those two video
layers will be affected by a main Take or Auto :

DSK 1 , currently seen on Program out, will be removed from view

DSK 2 will be displayed instead.

The BKGD layer will not change; hence Preview correctly shows no change.
The Look Ahead Preview allows you to switch with real confidence, while the Transition
Delegate feature provides flexible and convenient video layer management, and thus enhanced
control over your ultimate Program output composition.
