S_Grain 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. In the Sapphire Stylize effects submenu. Inputs: Source:  The current layer.   The clip to be processed.

Parameters:

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.

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

Color Frequency:   Default: 100,  Range: 0.1 or greater.
The frequency of the color grain. Increase for finer color grain, decrease for coarser color grain.

Red Freq:   Default: 1,  Range: 0.01 or greater.
The relative frequency of the red channel grain.

Green Freq:   Default: 1,  Range: 0.01 or greater.
The relative frequency of the green channel grain.

Blue Freq:   Default: 1,  Range: 0.01 or greater.
The relative frequency of the blue channel 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.

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

Bw Frequency:   Default: 100,  Range: 0.1 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.

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.
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.
