Main Controls - NewTek TriCaster 850 User Manual

Player (DDR, Still or Title) file that includes an embedded alpha channel, because LiveMatte or
Cropping are enabled for the source, or even all of the above
Regardless, DSK layers will automatically respect transparency when the source supplies it. The
BKGD layer (and, for DSK 2, its lower-numbered sibling) will appear through or around sources
with transparency as appropriate.
Important Note: Use straight (a.k.a. "non-premultiplied") alpha channels in TriCaster's media
players. Premultiplied files may not yield correct results when overlaid on other imagery.

TriCaster's DSK layers offer a lot of creative possibilities. You might use one DSK to display a
permanent station ID 'bug'. Or, you might superimpose a company logo from Still onto a title
page, add a 'spinning globe' animation playing in the DDR to a lower-third, 'frame' a keyed
source composed over a title (Figure 156), or set up many other elaborate effects in this manner.

MAIN CONTROLS

In large measure, TriCaster's main Transition controls (Take, Auto and the T-Bar) behave similarly
to their local sidekicks. What makes them special is the Transition Delegate button group located
just above the main T-Bar.
