In large measure, TriCaster’s main Transition controls behave similarly to their local sidekicks.  What makes them especially powerful is the T-bar and Transition Delegate button group located just above.

Transition control settings in this section apply to the Background video layer only. In most respects, these tools are identical to the DSK transition controls discussed earlier (Section 9.4.1), but there is one difference worth mentioning.
The Duration menu for the Background transition offers two additional items compared to the similar menu in the DSK control groups:
•    Reverse – configures the current transition to run in reverse direction the next time it is applied.

•    Ping Pong – when enabled, this option causes the direction of the transition to be automatically swapped after each time it is applied.

Transition Delegates

An executive maxim suggests “Don’t do anything yourself when you can delegate it”.  In TriCaster Advanced Edition, each video layer has its own small ‘confidence monitor.  To delegate the T-bar, Auto and Take controls to govern one or more layers in the Switcher or an M/E, simply click the monitor for the layer you want to control – whether the Background, or a DSK/KEY layer. 

To delegate multiple channels simultaneously, hold the CTRL key while clicking the monitors for the desired channels.  The monitor for delegated channel(s) will be shown with a blue border (see Figure 102). 


Figure 102

Let’s see how applying the concept of delegating controls affects their use:

  • Assign something suitable to the DSK 1 and DSK 2
  • Click the solo Take buttons in the DSK control groups to hide these DSK layers, if they are visible on output.
  • Click the small BKGD monitor left of the T-Bar.
  • Click the main Auto button (below the T-bar).
  • Now, hold down the Ctrl key and click the monitor for DSK 1. (Or, press both the BKGD and DSK 1 buttons on a TriCaster control surface Transition Delegate group at the same time.)

You have just delegated the controls to two video layers.  You can likely guess what comes next.

  • Press Auto or Take, and observe the result.
  • Now add DSK 2 to the delegate selection, and switch again.

The BKGD layer is updated, DSK 1 is removed, and DSK 2 is displayed.

Hint: The Look Ahead Preview monitor respects your Transition delegate selections, allowing you to configure layers for upcoming switcher operations with great confidence.

A progress bar beneath each of the DSK control groups tracks transition progress (progress bars remain fully ‘on’ when a layer is 100% displayed).

Let’s discuss the final button in the Transition group – FTB.
The acronym FTB stands for Fade to Black.  The result of clicking FTB will not likely surprise you very much. FTB offers a convenient method of doing precisely what its name implies – fading Program output completely to black.  It might help to think of FTB as a final video layer added above all others before Program output, completely obscuring everything below it.
As a memory aid, the FTB button pulses during operation.  FTB’s fade duration is drawn from the BKGD layer setting.  Hold down Shift while pressing the FTB on a control surface button to initiate an FTB operation.  
Note: Hiding or displaying FTB will trigger both Autoplay and Audio Follow Video when these settings are active for displayed Media Players.  FTB also fades Master Audio to mute when displayed, and back up again when hidden.

As we have seen, clicking the main Take button (keyboard shortcut Enter) performs a straight cut for all video layers that are currently selected (i.e., those whose monitors have blue borders due to you having clicked them).
Likewise, if you press Auto (or the keyboard Spacebar), the transitions assigned to all delegated video layers are performed.  You can halt an Auto operation partway by clicking the button a second time during the transition. The operation will be completed the next time you click the button.
Note that there are local (BKGD layer-only) Take and Auto buttons beneath the Background Transition icon.
The T-bar mimics the similar control on a traditional video switcher, and allows you to manually perform a transition between selected video layers. To use the T-bar, pull it downward by dragging it with the mouse pointer.  Drag it all the way to the bottom and release to complete a transition; the T-bar then pops back to the top.
Hint: Naturally, when the T-bar is dragged part way, a partial transition occurs.  With certain transitions this can be useful for split screen effects.
