Push
The availability of the Push function and the essence pushed depend on the configuration,
and are explained in the table below.
With some essence combinations, the user can specify in which codecs the clip should
be pushed, by means of the Codec target setting (Multicam Configuration module,
Operation page, Push section) of the source server.
In the Codec target setting, the user can choose between Intra or Intra+LongGOP.
When the Proxy codec is active on the source and destination, it shall always be pushed.

Clip Preload and Playout
Only one essence can be played out at a time. The codec used for playout, which is
automatically defined based on the following priority rules, is specified in the Server tab,
after the Codec sections:
• When the Intra essence is in use on the server, this essence shall be played out.
• Otherwise, the LongGOP essence will be played out.
• The Proxy essence will never be played out.
If the on-air essence of a clip is not available, the behavior is as follows:
• The clip shall be displayed as "Unplayable" on the VGA
• The clip LED shall be green on the Remote panel.
• The remote shall beep when the user tries to load the clip.
• A black clip shall be displayed.
