A typical use case is as follows: A Viz Trio user may want to add graphics to a video in Viz Trio’s Timeline editor. A video clip is dragged to the timeline, and also one or more data elements (graphics). In the Timeline editor, the graphics elements are added as placeholders on the video timeline. The user wants to display snapshots of the graphics on these placeholders, and hence a Preview Server connection has been set up (for details, see Configuring Preview Server Settings in Viz Trio). Viz Trio sends a request to the Preview Server, asking for an available Viz Engine that can generate the necessary preview snapshots. The Preview Server passes the task through to a suitable Viz Engine, which in turn generates the snapshots that were requested by Viz Trio.

When used together with Vizrt’s control applications Viz Multichannel, Viz Pilot, and Viz Trio, the Preview Server is installed from a stand alone installer.

Alternatively, when used in a workflow together with the Graphics Plugin for NLE, the Preview Server should be installed from a joint installer package, containing both the Preview Server and the Connection Broker.

For more details on this joint Preview Server and Connection Broker setup, see the Graphics Plugin for NLE Administrator’s Guide.
