We’ll look at the details of LiveMatte in more depth in Part II (the Reference section), but already
your result should look very similar to Figure 65. TriCaster doesn’t stop here, though. Let's
proceed into an introduction to
Virtual Inputs .
4.10 VIRTUAL INPUTS
Virtual Input buttons sit innocuously on TriCaster’s Switcher rows just like other video inputs,
but in fact they possess very powerful features. Virtual Inputs can be somewhat likened to the
M/E (Mix/Effect) rows of a traditional video switcher. They permit a composition to be prepared
from multiple sources (including an integrated
Overlay ).
4.10.1 COMPOSING INPUTS A AND B
Let’s begin our examination by re-constituting our simple keyer setup above, but this time doing
so using a
Virtual Input .
1. Change the Switcher’s Program row selection to V1 , and enable the BKGD delegate
button in the Transition section of the Switcher .
2. Remove any extraneous DSK s left from earlier operations from view, using the local
Take buttons in the Transition section of the Switcher .
3. Click the tab labeled V1 below the Switcher (to reveal the panel for Virtual Input 1 ).
Figure 67
4. Notice that the lower portion of the Virtual Input panel contains two source button
rows labeled Input A and Input B (Figure 67).
5. At the end of the previous section, we left the DDR 1 with LiveMatte enabled. Click
DDR 1 in the Input A row, designating it as the foreground stream for this Virtual Input .
