Installation and Configuration of the Preview Server

1. Install the Preview Server.

2. Open the Preview Server homepage/configuration page: Start > Vizrt > Preview Server Config. On the configuration page you can specify the host and port of the Viz Engine for which the Preview Server should connect to (see the illustration below).

   

   Note: Use Google Chrome or Firefox to view this page. Using Internet Explorer is not recommended.

3. Configure the Viz Pilot settings to use the installed preview server:

   • Open Start > Vizrt > Pilot Data Server Web Interface

   • Click Settings in the top menu.

   • For the preview_server_uri setting, provide the URL to the preview server, for example http://HOSTNAME:54000/ (see illustration below).

     

4. After applying this URL, restart the Viz Pilot REST server (the Viz Pilot Data Server provides this URL in its atom service document after restart).

Thumbnail Status

The graphic’s status is shown at the right side of the thumbnail for MOS-type elements.

• A red bar appears on the right side of the thumbnail of the graphic if any monitored resource (a staged image by Graphic Hub ImEx Agent, for example) of the graphics item is unavailable for playout.

  

• An orange warning bar appears on the right side of the thumbnail of the graphic if the graphics monitored resources are available but not fully loaded in the memory of the Viz Engine.

  

• A green OK bar appears if the graphics and their resources are available to the Viz Engine.

  

Status for CG Elements

Thumbnail status is not yet supported for CG elements. However, a workaround is available. It is possible to select to show a textual status in the page column.

The following statuses are shown:

• If any monitored resources (for example a staged image by Graphic Hub ImEx Agent) of the graphics item is unavailable for playout, the page text of the graphic is NOT READY.

• If the graphics monitored resources are available, but not fully loaded in the memory of the Viz Engine, the page column is shown as AVAILABLE.

• If the graphics and its resources are available and fully loaded, READY is shown.

Troubleshooting

If you want to clear old thumbnails, you can clear the cache with the following steps on the server:

1. Close the playlist in Avid MediaCentral® | Command Workstation.

2. Stop the Inventory Manager with Avid Workgroup Properties (see the following illustration).

   

3. Delete the thumbnail cache folder (<Program Files>\Avid\iNEWS Command\inventorymanager\state\thumbnailcache).

4. Restart the Inventory Manager.

5. After the alert shows in Command Workstation that the Inventory Manager is available again, re-open the playlist.

   Note: The Vizrt iNEWS Command Plug-in also has a cache. When restarting the plug-in, this cache is cleared.
