Adding a Viz Engine to Renderer Host (Media Sequencer)

  1. Open Preview Server’s Home page.

  2. Locate the Renderer Host in the main table to which you want to add a new Viz Engine. If no Renderer Host is available, add a new one first.

  3. Click the “+” button next to the Renderer Host entry.

  4. In the popup window, specify the hostname and port number where the Viz Engine is running.

Note: If port is not specified, Viz Engine is added with the default port number 50007. When using Viz Engines in a so-called dual channel setup, it is possible to run multiple instances of Viz Engine on a single host. Each instance uses a unique port, which means that only two Viz Engines should be considered duplicates when both the hostnames and port numbers are identical.

  1. Click the OK button to confirm the addition.

  2. The new Viz Engine should be displayed in the main table.
