Media within a playlist can be set to play in more specific patterns and timing.
Select the Playlist tab, choose the media whose parameters you wish to modify and click Edit.
Here you can choose a transition type, the duration that the media displays for, and when the media displays.
You can set the media to play on a particular date, time or time window, or even to just run once.
It is also possible to set the media to only display on particular players from among those using the playlist.
