11.1 Working with Two Graphics Cards

A machine with two graphics cards is, with Viz Engine 3.3 and later, able to run two

instances of Viz Engine simultaneously.

Currently there are three options;

1. Two program outputs

2. One program output and one preview output

3. One program output for stereoscopy

The first (1) option allows you to use two instances that can run two program channels,

e.g. one for SD and one for HD output.

The second (2) option allows you to run your control application using one instance for

preview and one for program output with video, ideal for OB environments.

The third (3) option allows you to produce graphics composited for stereoscopic use. In

addition you will also save rack unit space as all hardware is fitted into one machine.

Note: The limitations to such systems, in general and not limited to Vizrt alone, is

memory usage and access, and also lack of power redundancy.
