V P Star t T ime/End T ime—Set the star ting and
ending frames for the selected event within the
overall Video Post queue. Video Post renders the
event over the number of frames specified here.
Enabled—Enables or d isables the event. When
turned off, the event is disabled and Video Post
ignores it when rendering the queue. Each event
must be disabled indiv idually. For example,
disabling a composite layer event does not disable
the composited im age events. The range bars of
disabled events are unavailable in the event track
area.
