Technicolor3Strip In the S_Technicolor Plugin. Simulates the Technicolor 3-strip film process from 1935 through 1955. Three-strip Technicolor was a subtractive process which exposed three separate film strips through color filters, then applied complementary color dyes to the print according to the density of the original records. Technicolor was used for many films such as The Wizard Of Oz, Fantasia, and Gone With The Wind. Modern color film has much broader color filtering in the emulsion layers, so this effect simulates the narrower filters and sharper colored dyes of Technicolor which gave it its characteristic vibrancy. This effect also allows adding grain and color correction. Inputs: Source:  The clip to be processed.

Parameters:

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

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

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

Grain Amp:   Default: 0,  Range: 0 to 1,  Shared.
Scales the amplitude of the film grain that is added to the result. Set this to 0 to disable all grain.

Grain Blur:   Default: 0,  Range: 0 to 0.1,  Shared.
The grain is smoothed by this amount. Increase for coarser grain.

Tint:   Default rgb: [1 1 1].
Tints the image towards the given color.

Amount:   Default: 1,  Range: 0 or greater.
Amount of Technicolor effect to use. Set to zero to get the original source. Increase beyond to to oversaturate.

Show:   Popup menu,  Default: Result.
Shows either the final result, or any of various intermediate parts of the process.

Result:  Shows the final result.

Pure Colors:  Shows an RGB mask containing only the pure colors in the source.

Complementary Masks:  Shows a mask of the complementary colors used to apply the dyes to the final print.

Key Density:   Default: 0.1,  Range: 0 to 1.
From 1932 up to about 1945, the blank print started with a 50 percent black and white duplicate of the green original record. This increased apparent sharpness and improved contrast. Set this to 0.5 for a historically accurate key layer, but it will decrease the overall brightness. After 1945 the key layer was no longer needed due to improvements in the process.
