Pre-roll period — A programmable interval before the presentation starts. As an example,
pre-roll might allow audience members to take their seats after an announcement that the
show has begun.
Post-roll period — A programmable interval after the presentation ends. Select the Stop At
option to set a stop point for the timecode and for the screen to go black. As an example,
post-roll might allow the house lights to gradually brighten. Post-roll is also sometimes
known as “run-on.”
