22.5.4 TRANSITIONS
The transition control group offers
familiar controls, including a T-Bar,
transition selector and timing knobs,
along with AUTO and TAKE buttons.
These are all governed by delegates, as
discussed earlier.
The TRANSITION DELEGATE buttons
include BKGD, DSK 1, DSK 2, and FTB
(Fade to Black) buttons. These can be
multi-selected, and govern which video
layers are affected by operations
performed with the SELECT and RATE
knobs, AUTO and TAKE buttons, and the
T-Bar.
TriCaster’s Background layer effectively comprises the program output before any
DSKs (or M/E KEY) layers or FTB are considered. When MAIN is selected in the
SWITCHER DELEGATE group and the BKGD delegate button is selected alone, a TAKE
swaps the source selected on the PREVIEW row for the one shown on the PROGRAM
row. M/E selections in the SWITCHER DELEGATE group cause transition controls to
operate similarly on their respective targets.
If one or more DSKs is selected along with the BKGD delegate button, the display
state for the delegated DSK or KEY layer(s) will be affected as well. Depending on
their current status, this may bring them into view, or remove them from view. This
allows, for example, to simultaneously hide one DSK (such as a title page) while
revealing another, even as you bring in a new BKGD source. Or you can display and
hide both DSK channels in tandem.
