Sapphire Plug-ins for Autodesk: WarpPolarComp


In the S_WarpsComp Plugin.

Warps the source clip into a rounded disk shape. The vertical direction of the source image is mapped between the Inner Radius and Outer Radius, and the horizontal direction is rotated about the center based on the number of Angle Repeats and offset by Angle.


Front: The clip to use as foreground.

Back: Optional. The clip to use as background.

Matte: Optional. Specifies the opacities of the Front clip.


Load Preset: Push-button .
Brings up the Preset Browser to browse all available presets for this effect.

Save Preset: Push-button .
Brings up the Preset Save dialog to save a preset for this effect.

Inner Radius: Default: 0.25, Range: any.
The distance from the center where the bottom edge of the source clip is mapped.

Outer Radius: Default: 0.75, Range: any.
The distance from the center where the top edge of the input clip is mapped.

Angle: Default: 0, Range: any.
Rotation of the result, in counter-clockwise degrees.

Angle Repeats: Default: 1, Range: 0.01 or greater.
The number of copies of the source image to wrap around. This should be an integer to avoid a seam where the first copy connects to the last.

Center: X & Y,   Default: [0 0], Range: any.
The center of the disk, in screen coordinates relative to the center of the frame. This parameter can be adjusted using the Center Widget.

Stretch: X & Y,   Default: [1 1], Range: 0.01 or greater.
Scales the horizontal or vertical size of the disk shape.

Filter: Check-box,  Default: on.
If enabled, the image is adaptively filtered when it is resampled. This gives a better quality result when parts of the image are warped smaller.

Wrap: X & Y,  Popup menu,  Default: [ Tile No ].
Determines the method for accessing outside the borders of the source image.
No: gives black beyond the borders.
Tile: repeats a copy of the image.
Reflect: repeats a mirrored copy. Edges are often less visible with this method.

Comp Premult: Check-box,  Default: off, Shared .
Enable this for a better composite if the Foreground pixel values have been pre-multiplied by the Matte pixel values. This is also known as an 'additive' composite.



Mocha: Default: 0, Range: 0 or greater, Shared .
Brings up the Mocha window for tracking footage and generating masks.

Blur Mocha: Default: 0, Range: 0 or greater, Shared .
Blurs the Mocha Mask by this amount before using. This can be used to soften the edges or quantization artifacts of the mask, and smooth out the time displacements.

Mocha Opacity: Default: 1, Range: 0 to 1, Shared .
Controls the strength of the Mocha mask. Lower values reduce the intensity of the effect.

Invert Mocha: Check-box,  Default: off, Shared .
If enabled, the black and white of the Mocha Mask are inverted before applying the effect.

Show Mocha Only: Check-box,  Default: off, Shared .
Bypass the effect and show the Mocha Mask itself.

Bypass Mocha: Check-box,  Default: off, Shared .
Ignore the Mocha Mask and apply the effect to the entire source clip.
