Sapphire Plug-ins for Autodesk: CloudsColorSmoothComp

CloudsColorSmoothComp

In the S_CloudsComp Plugin.

Generates a full color clouds texture, and combines that with a background clip. Procedural noise texture is independently generated for each of the red, green, and blue output channels.

Inputs:

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

Parameters:

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.

Frequency: Default: 8, Range: 0.01 or greater.
The spatial frequency of the clouds. Increase to zoom out, decrease to zoom in. Very high values of Frequency are clamped internally so the grain size is no smaller than a few pixels. If you want even finer grain use S_Grain or S_Clouds:Perspective instead.

Frequency Rel X: Default: 0.2, Range: 0.01 or greater.
The relative horizontal frequency of the texture. Increase to stretch it vertically or decrease to stretch it horizontally.

Octaves: Integer,  Default: 1, 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.

Seed: Default: 0.6, 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.

Shift Start: X & Y,   Default: [0 0], Range: any, Shared .
Translation offset of the texture. Since the texture is procedurally generated it can be shifted with no repeating units or seams occurring.

Shift Speed: X & Y,   Default: [0.5 0], Range: any, Shared .
Translation speed of the texture. If non-zero, the result is automatically animated to shift at this rate. The result of animated Speed values may not be intuitive, so for variable speed motion it is usually best to set this to 0 and animate the Shift Start values instead.

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

Scale Colors: 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.

Saturation: Default: 1, Range: 0 or greater.
Scales the color saturation. Increase for more intense colors. Set to 0 for monochrome.

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.
Clouds Only: gives only the clouds texture 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 clouds.

Params2:

Params3:

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.
