This section introduces some of the custom controls that might appear in the Effect Editor for an AVX plug-in effect. For more information on using these controls, and other controls specific to individual effects, see the documentation for the plug-in.

Some plug-in effects allow you to adjust an image using controls that appear as overlays, such as handles and wire frames, in the Effect Preview monitor. You access these overlays by clicking the Outline/Path button at the bottom of the Effect Editor. In some cases, you can then access additional controls by clicking buttons on the right side of the Effect Editor.

The Angle parameter category is not available in standard Avid effects but is available with some AVX plug-in effects. It allows you to manipulate an effect's angle or direction by dragging within a graphic representation of a circle to alter the angle or direction value. Values can be positive or negative and are not limited to a single 360o rotation.
