GrainColor In the S_Grain Plugin. Adds color and/or monochrome grain to the source clip. Amplitude and frequency parameters allow adjusting the grain texture independently for all colors together, each color channel, or black and white grain. Inputs: Source:  The clip to be processed.

Parameters:

Color Amplitude:   Default: 0.1,  Range: 0 or greater.
The amplitude of color grain to include.

Color Frequency:   Default: 100,  Range: 0.01 or greater.
The frequency of the color grain. Increase for finer color grain, decrease for coarser color grain.

Color Octaves:   Integer,  Default: 1,  Range: 1 to 10.
The number of octaves of color grain to include. Each octave is twice the frequency and half the amplitude of the previous.

Seed:   Default: 0.123,  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.

Jitter Frames:   Integer,  Default: 1,  Range: 0 or greater,  Shared.
If this is 0, the noise texture will remain the same for every frame processed. If it is 1, a new noise texture is used for each frame. If it is 2, a new noise texture is used for every other frame, and so on.

Red Freq:   Default: 1,  Range: 0 or greater.
The relative frequency of the red channel grain.

Green Freq:   Default: 1,  Range: 0 or greater.
The relative frequency of the green channel grain.

Blue Freq:   Default: 1,  Range: 0 or greater.
The relative frequency of the blue channel grain.

Color Scale:   Default rgb: [1 1 1].
Scales the color of the grain by this value. The grain will include both positive and negative values of this color.

Bw Amplitude:   Default: 0.05,  Range: 0 or greater.
The amplitude of black and white grain to include.

Bw Frequency:   Default: 100,  Range: 0.01 or greater.
The frequency of the black and white grain. Increase for finer grain, decrease for coarser grain.

Bw Octaves:   Integer,  Default: 1,  Range: 1 to 10.
The number of octaves of black and white grain to include. Each octave is twice the frequency and half the amplitude of the previous.
