Looping Playlist Elements
When the user creates or deletes a loop in a Fill (or Key) playlist, the same operation is
performed on the corresponding Key (or Fill) playlist.
See section "Looping Playlist Elements During Playout" on page 109 more information on
loops.
Associating an Auxiliary Clip to a Fill or Key Playlist
Associating an auxiliary clip to a Fill (or Key) playlist can be done in the same way as for a
Normal playlist. See section "Associating an Auxiliary Audio Clip to a Playlist" on page
118.
The system associates the auxiliary clip to the Fill (or Key) playlist but does not perform
any operation on the corresponding Key (or Fill) playlist.
2.3.5. Black Clips Management
Introduction
A black clip is a clip represented by a black sequence in the video track and a mute
sample in the audio track.
It can be automatically inserted in a playlist under specific circumstances when working
with Fill and Key playlists.
Moreover, a black clip can also be manually inserted as described in "How to Manually
Insert a Black Clip in a Playlist" on page 171.
When inserted into a playlist, a black clip is played out like a normal element. Therefore, it
is taken into account for on-air time calculation and remaining time calculation. Black clip
related information will be displayed on OSD while played out. Almost all operations
allowed on playlist elements will be possible on a black clip. Refer to section "Limitations"
below for restriction on authorized operations. In addition, when a playlist containing black
clips is copied to another EVS video server, black clips are kept.
Limitations
1. A black clip will not be seen in the Database Explorer.
2. It is not possible to load a black clip as a clip on a Control Panel.
3. The following operations cannot be performed on a black clip: copy, move, update,
delete, backup, restore
4. A black clip cannot be renamed.
5. The only type of tag allowed on a black clip is GPI. That is understandable as there is
no audio on black clips.
6. The following types of macro command cannot be performed on a black clip:
Hide/mute/audio swap
