Sapphire Plug-ins for Autodesk: TextureChromaSpiralCmp


In the S_TexturesComp Plugin.

Creates an abstract texture by applying a WarpChroma effect to a procedurally generated noise texture, then combines the texture with a background clip.


Back: The clip to combine the texture image with. This may be ignored if the Combine option is set to Texture Only, but the output clip will default to the same length as this 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.

Noise Frequency: Default: 6, Range: 0 or greater.
The spatial frequency of the initial noise texture. Increase to zoom out, decrease to zoom in.

Noise Octaves: Integer,  Default: 3, Range: 1 to 10.
The number of summed layers of noise. Each octave is twice the frequency and half the amplitude of the previous. A single octave gives a smooth texture. Adding octaves makes the result approach a fractal (1/f) noise texture.

Noise Shift: X & Y,   Default: [0 0], Range: 0 or greater.
Translation offset of the initial noise texture.

Noise Seed: Default: 0.23, Range: 0 or greater.
Used to initialize the random number generator. The actual seed value is not significant, but different seeds give different results and the same value should give a repeatable result.

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

Z Dist: Default: 0.7, Range: any.
The distance that the chroma warp effect is applied over.

Rotate: Default: -8, Range: any.
The rotation of the spiral, in degrees. Set to 0 for a straight zoom.

Brightness: Default: 1, Range: 0 or greater.
Scales the brightness of the result.

Color: Default rgb: [1 1 1].
Scales the color of the result. For example, if it is yellow [1 1 0], the blue of the result will be 0.

Steps: Integer,  Default: 12, Range: 3 to 100.
The number of color samples along the spectrum to include. More steps give a smoother result, but require more time to process.

Offset: Default: 0, Range: any.
Adds this gray value to the result (or subtracts if negative). 0 has no effect, .5 is middle gray, and 1 is white.

Combine: Popup menu,  Default: Screen .
Determines how the texture is combined with the Background.
Texture Only: gives only the texture image with no Background.
Mult: the texture is multiplied by the Background.
Add: the texture is added to the Background.
Screen: the texture is blended with the Background using a screen operation.
Difference: the result is the difference between the texture and Background.
Overlay: the texture is combined with the Background using an overlay function.

Scale Back: Default: 1, Range: any, Shared .
The background brightness is scaled by this value before being combined with the texture.

Wrap: Popup menu,  Default: Reflect .
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.



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.
