Overlay Graphics

The Overlay Graphics interface provides control and monitoring of overlay graphics for all Viz Mosart-approved graphic engines.

Start Overlay Graphics by double-clicking the application icon:

images/download/thumbnails/68863552/mosart_icons_icon_overlay_graphics.png or by navigating to the installation directory (by default C:\Program Files (x86)\Mosart Medialab\Mosart Server) executable MMOverLayGraphicsInterface.exe.

The Overlay Graphics Interface (and application icon) is only available if Overlay Graphics was selected when installing the Viz Mosart Server.

The Overlay Graphics interface is only used for overlay graphics. Full-frame graphics are controlled through the AV Automation application.

A menu bar at the top offers Settings, Graphics profile, Tools and Standby.


The Overlay Graphics interface consists of four main areas ([1] to [4] in the illustration).

A status bar at the foot of the UI provides information on product version number and the total number of graphics in Viz Mosart (rundown overlays + named overlays + button overlays. 7 in the example above).

[1] List of Overlay Graphics in the Rundown


The main column labels are:

  • Time: The time when the graphic was added in Overlay Graphics (usually at rundown import).

  • #U: The number of times this graphic has been updated.

  • #T: The number of times this graphic has been taken.

  • Type: The graphic type. Can be:




    Auto Out (a Manual CG can also be Auto Out)


    Background End


    Story End


    Manual (Open End)


    Last Out


    Stay Always


    if template is STORYSTART


    None of the above

If the graphic is a locator, then the type is suffixed with an "L".

Note: Locator is a special graphics item that is linked to a video server crosspoint. When taking the crosspoint from a Viz Mosart template, either as a switcher crosspoint or keyed crosspoint (in a DVE box), the graphics are also (re-)taken.
