BleachBypass Simulates a film process in which silver is not removed from the negative. The result has increased contrast and reduced color saturation. Inputs: Source:  The clip to be processed.

Parameters:

Amount:   Default: 1,  Range: 0 or greater.
Controls the intensity of the effect by interpolating between the original source and the result.

Soft Focus:   Default: 0,  Range: 0 or greater.
If positive, a soft focus effect is also applied. Increase for a broader soft focus look.

Sharpen:   Default: 0,  Range: any.
The amount of post-process sharpening applied.

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

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

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

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.

Grain Parameters:

Grain Amp:   Default: 0,  Range: 0 or greater.
Scales the amplitude of the film grain that is added to the result. Set this to 0 to disable all grain.

Grain Amp Red:   Default: 0.9,  Range: 0 or greater.
Scales the red grain amplitude.

Grain Amp Green:   Default: 1,  Range: 0 or greater.
Scales the green grain amplitude.

Grain Amp Blue:   Default: 1.6,  Range: 0 or greater.
Scales the blue grain amplitude. Note that grain is added and subtracted from the image, so for example, increasing Grain Amp Blue will amplify both the blue and yellow speckles.

GrainAmpDarks:   Default: 0.2,  Range: 0 or greater.
The relative amount of grain applied to the darkest regions of the image, per channel. This defaults to less than 1.0 because dark areas usually have less grain than midtones.

GrainAmpBrights:   Default: 0,  Range: 0 or greater.
The relative amount of grain applied to the brightest regions of the image, per channel. This defaults to zero because bright areas usually have less grain than midtones. Note that highly saturated colors can be affected by both Grain Amp Darks and Grain Amp Brights because they are dark in some color channels and bright in others.

Grain Blur:   Default: 0,  Range: 0 or greater.
The grain is smoothed by this amount. Increase for coarser grain.

Grain Blur Red:   Default: 1,  Range: 0 or greater.
The relative blur amount for the red grain.

Grain Blur Green:   Default: 0.9,  Range: 0 or greater.
The relative blur amount for the green grain.

Grain Blur Blue:   Default: 1.2,  Range: 0 or greater.
The relative blur amount for the blue grain.

Grain Seed:   Default: 0,  Range: 0 or greater.
Initializes the random number generator for the grain generation. The actual seed value is not significant, but different seeds give different grain patterns and the same value should give a repeatable pattern.

Grain Mono:   Check-box,  Default: off.
When enabled, the same grain pattern is used for the red, green, and blue channels. To make truly monochrome grain you should also set Grain Amp Red/Green/Blue equal to each other, make sure Midtone Pos Red/Green/Blue are equal, and if GrainBlur is positive also set Grain Blur Red/Green/Blue equal
