Viz Engine Administrator’s Guide

• Clip1: Clip playback is available in Viz Artist Clip1.

Usually Matrox’ ClipIn1 is mapped to Viz Engine’s Clip1 and ClipIn2 to Clip2 and so on.

When a machine has two graphics cards installed (i.e. a dual channel or Viz Trio Box

setup) you should note that clip channels are not hardware resources on the Matrox

board, hence, both instances can address 2 clip channels each. Limiting factors are

performance and number of DVE layers.
