Otherwise, dragging vertically changes the height of the overlay, and dragging horizontally
affects its width.
Again, if you drag just one of the numeric gadgets below the Size button (with lock disabled ), you
modify just one dimension of the overlay stream – width or height. Position and Size can be
reset by clicking Reset Positioning , and can be toggled on or off by clicking the Position button
located to the left of the Configure button (gear).
You will likely have realized by now that simply using the Virtual Input controls considered so far,
you could scale a live video source down, and position it above another source to create a
picture-in-picture effect – or even two live insets (with a black background).
15.3 OVERLAY
Figure 170
A control group labeled Overlay is situated just above the Position button for Input A . The
Virtual Input overlay feature is very similar to the Overlay channels found on the Switcher.
However, unlike them, since it is assigned to the Virtual Input it is applied before that
composition is sent to the Switcher. Thus content in this overlay channel appears beneath
anything displayed via the two (Switcher) Overlay channels on Program Output .
The Effect selection drop-down and activation buttons, as well as Position controls work just like
their main Switcher cousins, as well.
