The playout of the playlist element continues after its OUT point for the Post-Roll
duration and then stops.
Post-Roll Characteristics
•
The Post-Roll duration is independent of the speed of the playlist. This means
that the playlist will continue to be played after the OUT point for the duration
of the Post-Roll, whatever the speed of the element may be.
For example, if the Post-Roll duration is set to 2 sec, the element will be played
after its OUT point during 2 sec at the speed defined.
•
The Post-Roll duration can be shortened if there is not enough A/V material in
the guardband. In this case, the playout will freeze on the Protect OUT point of
the playlist element.
For example, if the Post-Roll duration is set to 3 sec, if the guardband length of
the element is 2 sec, and if the speed of the element is 100%, the element will
be played during 2 sec after its OUT point and stops on its Protect OUT point. If
its speed is 50%, there will be enough material to play during the 3 sec of Post-
Roll duration.
•
The Post-Roll duration can be modified at any time, should the Post-Roll option
be activated or not.
•
The Post-Roll is activated for a channel and not for a specific playlist.
•
The playlist transport commands are available during the Post-Roll duration.
