The Video Post queue in the Video Post dialog is similar to other hierarchical
lists in the Track View and Material Editor. In Video Post, the list items are
images, scenes,
animations on page 7711 , or external processes that together
make up the queue. The items in the queue are called 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, or above, the image that is to
overlay it.
There is always at least one item in the queue (a placeholder labeled Queue).
It is the queue's parent event.
The queue can be linear, but some kinds of events, such as Image Layer,
combine other events and become their parent.
Procedures
To add an event to the queue:
■ Click an event button.
When you add an event, a dialog displays where you can specify settings
for that event. The settings offered on the dialog depend on the type of
event; some events have different kinds of subtypes.
In general, the new event appears at the end of the queue - but some kinds
of events require that you first select one or more events in the queue. An
