The BKGD layer is updated, DSK 1 is removed, and DSK 2 is displayed.
Hint: The Look Ahead Preview monitor (Section 9.2) reflects your Transition Delegate selections,
and allows toy to configure video layers for upcoming switcher operations with great confidence.
A progress bar beneath the each of the Delegate buttons tracks transition progress. (For the two
DSK layers, the bar will remain fully ‘on’ when the related layer is 100% displayed).
FTB
Let’s discuss the final button in the Transition Delegate group - FTB . The acronym stands for
Fade to Black . The result of selecting the button and displaying the video layer it controls will
not likely surprise you very much. FTB offers a convenient method of doing precisely what is
implied by its name, simply fading Program Output out completely (to black).
It might help to think of FTB as ‘DSK 3’, since it represents a final video layer added above all
others before ultimate Program output. FTB has several unique characteristics, however. For
one thing, DSK 1 and 2 can display colorful video sources (with or without transparency); the FTB
video layer is always 100% opaque black, and completely obscures everything below it.
Note: Like the DSK layers, hiding or displaying FTB triggers both Autoplay and Audio Follow Video
when these settings are active for Media Players. FTB also fades Master Audio to mute when
displayed, and back up again when hidden.
Also unlike other video layers, FTB does not support custom transitions (pressing Auto simply
fades it on or off) or timing; FTB’s fade duration is drawn from the BKGD layer setting.
TAKE AND AUTO
As we have seen, clicking the main Take button (keyboard shortcut Enter ) performs a straight cut
for all video layers (BKGD, DSK 1, DSK 2, and FTB) that are currently selected in the Transition
Delegate group.
Likewise, if you press Auto (or the keyboard Spacebar ), transitions configured at right for all
delegated video layers are performed.
