Grass Valley K2 AppCenter v.9.0 - Manual (Page 94)

Introducing the Playlist application
In addition to playing a single clip, AppCenter play channels can also play lists that contain clips
and programs stored on the K2 system.
The following table summarizes the basic features supported in playlist application.
Description Basic Feature
Events in a playlist can be rearranged or removed, and new events
added between existing ones. Editing playlists
Events can be renamed and trimmed. Trimming an event moves the
mark-in and mark-out points. This only affects the event, not the source
clip. Editing events in the list
Transitions between all events in a list are made by a cut, i.e. the last
frame of an event is followed by the first frame of the next event. Event transitions
Sections are provided within the list to provide flexibility during
playout. A section can be set up to loop indefinitely. The section can
be taken out of the loop by manual intervention. Loop on a section
Lists can be set up to loop indefinitely. The list can be taken out of the
loop by manual intervention. Loop on a list
Events can pause playout at their end. At event pauses, you can choose
to show black, freeze on last frame, or freeze on next event. Pause at the end of events
Sections can pause playout at their end. At section pauses, you can
choose to show black, freeze on last frame, or freeze on next event. Pause at the end of sections
Playlists can be saved as a program. This saves the media and
transitions, but nothing that breaks the flow of playout, such as pauses.
You can insert a program into a playlist, or play a program in the
standard Player application. Saving a playlist as a
program
AppCenter provides 12 GPI output signals through a rear panel
connector for controlling external equipment. You can configure events
in a playlist to trigger GPI outputs. A GPI trigger does not disrupt
playout of the play events. GPI triggers can be set to occur at the
beginning or end of an event or section, or at these points with some
offset. GPI output triggers
You can assign any of the 12 GPI inputs to control one or more play
channels and the action you want the AppCenter channel(s) to take—
play, VAR play, cue next event, or cue next section, etc. AppCenter
includes more extensive GPI output trigger features. GPI Input triggers
