S_Posterize Generates a posterized version of the input by limiting the number of colors in the source, and replacing detailed texture and noise with solid colors. In the Sapphire Stylize effects submenu. Inputs: Source:  The clip to be processed.

Parameters:

Amount:   Default: 0.1,  Range: 0 to 1.
Increase this for fewer and larger regions of solid colors. Decrease for more colors and more steps between colors.

Preserve Chroma:   Default: 1,  Range: 0 to 1.
If set to 1, posterizes only the luma of the clip, leaving chroma unchanged. If set to 0, posterizes the RGB, affecting both luma and chroma which usually results in more color fringes between regions. Intermediate values interpolate between the two results.

Smooth Edges:   Default: 0.1,  Range: 0 to 1.
Amount to smooth the edges between color regions when posterizing. Increase this value to reduce aliasing between the colored areas. If set to 1, the areas will be completely smoothed together and no posterize effect will occur.

Smooth Source:   Default: 0.002,  Range: 0 or greater.
Amount to blur the input clip before posterizing. Increase this value to reduce noise or jagged edges.

Color Phase:   Default: 0,  Range: any.
Amount to shift color boundaries when posterizing. Adjust this to fine-tune the location of the edges between the color regions. A phase of 1 is equivalent to 0.

Phase Red:   Default: 0,  Range: any.
Amount to shift the red channel boundaries when not preserving chroma. If Preserve Chroma is 1.0 this has no effect.

Phase Green:   Default: 0,  Range: any.
Amount to shift the green channel boundaries when not preserving chroma.

Phase Blue:   Default: 0,  Range: any.
Amount to shift the blue channel boundaries when not preserving chroma.

Scale Lights:   Default: 1,  Range: 0 or greater.
Scales the result by this value. Increase for a brighter result.

Offset Darks:   Default: 0,  Range: -8 to 2.
Adds this gray value to the darker regions of the result. This can be negative to increase contrast.

Saturation:   Default: 1,  Range: -2 to 8.
Scales the color saturation. Increase for more intense colors. Set to 0 for monochrome.
