Video Post Queue
Video Post Queue provides a hierarchical list of
the images, scenes, and events to be composited.
TheVideoPostqueueintheVideoPostdialogis
simila r to other hierarchical lists in the Track View
and Material Editor. In Video Post, the list items
are images, scenes,
animations (page 3–1003)
,
or external processes that together make up the
queue.Theitemsinthequeuearecalled
events
.
The order that the events appear in the queue is
the order in which they are executed, from top to
bottom. Consequently, to correctly composite
an image, the background bitmap must appear
before,orabove,theimagethatistooverlayit.
