Instant Prerolls
Use Instant Prerolls
Instant Preroll provides instant play/skip capability to the device. It allows the device to
have its own short preroll for manual intervention in the list. The feature is designed for
coming out of a live or upcounting event as fast as possible when the next event has a
near-instant preroll. When using a master control switcher, the preroll must not be shorter
than the shortest preroll supported by the switcher.
When Use Instant Prerolls is enabled, values for preroll seconds and frames must be
entered. The preroll value must be at least 4 frames. These values do not have any effect if
the Use Instant Prerolls box is left unchecked.
Switch Only
Select a Switch Only device configured in the previous tab. The settings chosen in the
Prerolls/Postrolls tab must be repeated for each Switch Only device. Default is disabled
for each device.
