4.10.2 ADDING AN UPSTREAM OVERLAY
Figure 70
Just above the Input A row, you’ll see a darker control area labeled Overlay .
The Overlay feature in Virtual Input tabs is, of course, upstream of the Switcher . It works very
much like the two downstream DSK video layers we used back in Sections 4.6.1 and 4.6.2, but
since Virtual Inputs are in the Background layer, content in this overlay channel appears beneath
anything you display in those two video layers on Program Output .

10. Access the Titles player, and click the “ Breaking News.CGXML ” icon (imported back in
Section 4.2) from the Practice Sessions folder.
11. Edit the top line in the title to say “5 Day Forecast”, as shown in Figure 71.
12. Select Titles in the V1 tab’s Overlay row, and display the Virtual Input’s overlay channel
by clicking the Auto button (in the Overlay Transition area of the VI tab).
