Virtual set

All Ultra sessions have a virtual set. A virtual set can be as simple as one of
the Simple Keyed virtual sets—which are empty sets—or as complex as one of
the sets in the Master Sets Libraries. Some virtual sets have transparent
(alpha) regions for insets, with a predefined scale, position, and orientation.
Some virtual sets also have foreground elements such as doors, desks, and
podiums. To customize the colors or otherwise manipulate the layers of a
virtual set, you must switch from the standard User-Defined Inputs mode to
the Pre-Defined Inputs mode (View > Displayed Inputs > Pre-Defined). For
more information about virtual sets, see

“Virtual sets” on page 24

.

Ultra comes with a few included virtual sets, including one of the Master Sets
Libraries, MSL1. Adobe sells additional collections of virtual sets as Master
Sets Libraries. You can also create your own custom virtual sets.
