Shutter Effects; Keystone Correction And Shutter Shape Preview - High End Systems CATALYST Series User Manual

CHAPTER 11
Keystone and Shutters

Shutter Effects

The eight Keystone Correction parameters also adjust the shape of shutter effects on a
layer.
To activate the shutter affects of the Keystone Correction parameters, the Visual Effects
parameter must be assigned to a DMX value between 60 and 72. A DMX value of 70
(Shuttered Black) is the most commonly used.
When a shutter Visual Effect is activated on a layer, that layer changes to a shutter only
layer. Any assigned content for the layer will not be displayed. Instead, an adjustable
transparent frame is displayed above underlying layers. A shutter Visual Effect will not
function on Layer 1.
Once a layer becomes a shutter only layer, the Keystone Correction parameters can be
used to adjust the frame's shape. In addition the X, Y, and Z Rotation, X and Y Position,
and Scale parameters modify the appearance of the shutters.

Keystone Correction and Shutter Shape Preview

You can also preview shapes created by the Keystone Correction parameters in the
Catalyst Control interface window on the PowerMac monitor. This field will display the
Keystone correction shape or shutter shape regardless of the active Visual Effect.
