Overlay Graphics Configuration

Overlay Graphics Configuration Window

The Overlay Graphics Configuration (OGC) window provides options for the Overlay Graphics interface.

  • In the Overlay Graphics application, select Settings > Properties to open.

  • Select (double-click) an object (here: the controller named HEGO).
    The form displays more information.

  • Controllers, Engines and Destinations


    A controller defines the type of the graphics system that is to be used. For each controller, both common and specific properties can be configured as described below.

    As a rule, connection settings for the graphics system are not defined at Controller level. However, for some graphic handlers, connection definitions to auxiliary components must be provided (for example, when connecting to the Media Sequencer for Vizrt graphics systems).



    For each controller, one or more engines can be added. An engine defines the connection to the graphics system.



    The destination defines the output channels where you play out the graphics.
