Sapphire Plug-ins for After Effects: TextureChromaSpiral


Creates an abstract texture by applying a WarpChroma effect to a procedurally generated noise texture.

In the Sapphire Render effects submenu.


Background: The current layer. The clip to combine the texture image with. This may be ignored if the Combine option is set to Texture Only.

Mask: Defaults to None. Interpolate between the result and the Source input. White areas use the result of the effect. Black areas use the Source 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.

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

Blur Mocha: Default: 0, Range: 0 or greater.
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.
Controls the strength of the Mocha mask. Lower values reduce the intensity of the effect.

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

Resize Mocha: Default: 1, Range: 0 to 2.
Scales the Mocha Mask. 1.0 is the original size.

Resize Rel X: Default: 1, Range: 0 to 2.
The relative horizontal size of the Mocha Mask.

Resize Rel Y: Default: 1, Range: 0 to 2.
The relative vertical size of the Mocha Mask.

Shift Mocha: X & Y,   Default: [0 0], Range: any.
Offsets the position of the Mocha Mask.

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

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

Combine Masks: Popup menu,  Default: Union .
Determines how to combine the Mocha Mask and Input Mask when both are supplied to the effect.
Union: Uses the area covered by both masks together.
Intersect: Uses the area that overlaps between the two masks.
Mocha Only: Ignore the Input Mask and only use the Mocha Mask.

Noise Frequency: Default: 6, Range: 0.01 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: any.
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.

Z Dist: Default: 0.7, Range: 0.001 or greater.
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.

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.

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.

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.

Bg Brightness: Default: 1, Range: 0 or greater.
The background brightness is scaled by this value before being combined with the texture.

Combine: Popup menu,  Default: Texture Only .
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.

Input Opacity: Popup menu,  Default: Normal .
Determines the method used for dealing with opacity/transparency.
All Opaque: Use this option to render slightly faster when the input image is fully opaque with no transparency (alpha=1).
Normal: Process opacity normally.
As Premult: Process as if the image is already in premultiplied form (colors have been scaled by opacity). This option also renders slightly faster than Normal mode, but the results will also be in premultiplied form, which is sometimes less correct.

Output Opacity: Popup menu,  Default: Copy From Input .
Determines the opacity/transparency of the result. This effect does not process the opacity (alpha channel) of its input but it can either copy the opacity from the input, or output a fully opaque result.
All Opaque: Makes the result fully opaque with no transparency.
Copy From Input: Copies the opacity/transparency from the current layer given to this effect.

Mask Use: Popup menu,  Default: Luma .
Determines how the Mask input channels are used to make a monochrome mask.
Luma: the luminance of the RGB channels is used.
Alpha: only the Alpha channel is used.

Blur Mask: Default: 0.05, Range: 0 or greater.
Blurs the Matte input by this amount before using. This can provide a smoother transition between the matted and unmatted areas. It has no effect unless the Matte input is provided.

Invert Mask: Check-box,  Default: off.
If on, inverts the Matte input so the effect is applied to areas where the Matte is black instead of white. This has no effect unless the Matte input is provided.
