Sapphire Plug-ins for Autodesk: VintageColor3Strip


In the S_VintageColor Plugin.

Simulates the color 3-strip film process from 1935 through 1955. Three-strip color 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. This process 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 the era which gave it its characteristic vibrancy. This effect also allows adding grain and color correction.


Source: The clip to be processed.


Load Preset: Push-button .
Brings up the Preset Browser to browse all available presets for this effect.

Save Preset: Push-button .
Brings up the Preset Save dialog to save a preset for this effect.

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 the 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.



Mocha: Default: 0, Range: 0 or greater, Shared .
Brings up the Mocha window for tracking footage and generating masks.

Blur Mocha: Default: 0, Range: 0 or greater, Shared .
Blurs the Mocha Mask by this amount before using. This can be used to soften the edges or quantization artifacts of the mask, and smooth out the time displacements.

Mocha Opacity: Default: 1, Range: 0 to 1, Shared .
Controls the strength of the Mocha mask. Lower values reduce the intensity of the effect.

Invert Mocha: Check-box,  Default: off, Shared .
If enabled, the black and white of the Mocha Mask are inverted before applying the effect.

Show Mocha Only: Check-box,  Default: off, Shared .
Bypass the effect and show the Mocha Mask itself.

Bypass Mocha: Check-box,  Default: off, Shared .
Ignore the Mocha Mask and apply the effect to the entire source clip.
