Distorts the pixels starting at the circumference of a circle and emanating outward.
Effect Parameters
Presets
Presets contain a snapshot of the plug-in parameters. The Presets control lets you choose among one of the presets built into the plug-in, save current parameter values to a preset file, or load an existing preset file from disk.
A preset file saved to disk via the "Save As" button can be loaded from another instance of the same plug-in by clicking the "Open" button. Presets generated in one host can also be loaded from the same plug-in when used in a different host.
Center
The center of the circumference.
Radius
The radius of the circumference.
Correct for Aspect Ratio
Scales the image to its natural display aspect ratio before the effect is applied. This parameter guarantees that geometric features in the effect appear undistorted when the footage is viewed at its display aspect ratio.
This parameter should be enabled for most footage whose display aspect ratio differs from the native aspect ratio of the codec, e.g. NTSC DV frames recorded at 720x480 pixels and displayed at 4:3 (640x480 pixels), or HDV frames recorded at 1440x1080 and displayed at 16:9 (1920x1080 pixels).
Disable this option if you have already taken steps to adjust the frame aspect ratio and/or notice that this parameter is causing unwanted distortion in your footage rather than preventing it.
Using the Effect with Anamorphic Footage
While Motion already includes an Image Unit that produces similar results, this FxFactory plug-in will honor the pixel aspect ratio of your footage to produce consistent results. Circular features will not become oval, and square features will not become rectangular.
