Sapphire Plug-ins for Autodesk: RackDefocusMono


In the S_RackDefocus Plugin.

Similar to RackDefocus, but first makes the source monochrome and then defocuses the resulting single channel (faster), using a 'circle of confusion' convolution. This effect is often preferable to a gaussian blur for simulating a real defocused camera lens, because bright spots can be defocused into clean circles instead of being smoothed away.


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.

Defocus Width: Default: 0.1, Range: 0 or greater, Shared .
The width of the defocus. This parameter can be adjusted using the Width Widget.

Rel Height: Default: 1, Range: 0.01 or greater, Shared .
The relative height of the iris shape. If it is not 1, circles become ellipses, etc.

Gauss Blur: Default: 0, Range: 0 or greater, Shared .
If positive, a gaussian blur is also applied which smooths out the edges of the shapes. This might also darken the highlights because Gamma is not considered in the gaussian blur.

Use Gamma: Default: 1, Range: 0.1 or greater, Shared .
Values above 1 cause highlights in the source clip to keep their brightness after the defocus is applied.

Boost Highlights: Default: 0, Range: 0 or greater, Shared .
The amount to increase the luma of the highlights in the source clip. Increase this parameter to blow out the highlights without affecting the darks or mid-tones.

Hilite Threshold: Default: 0.9, Range: 0 or greater, Shared .
The minimum luma value for highlights. Pixels brighter than this will be brightened according to the Boost Highlights parameter.

Shape: Popup menu,  Default: Circle .
Determines the shape of the simulated camera iris.
Circle: round.
3 sides: triangle.
4 sides: square.
5 sides: pentagon.
6 sides: hexagon.
7 sides: etc.

Roundness: Default: 0, Range: any, Shared .
Modifies the shape of the simulated camera iris. A value of 1 produces a circle; 0 gives a flat-sided polygon with a number of sides given by the Shape parameter. Less than 0 causes the sides to squeeze inward giving a star shape, while a value greater than 1 causes the corners to squeeze inward, giving a flowery shape. Has no effect if the Shape is set to Circle.

Rotate: Default: 0, Range: any, Shared .
Rotates the iris shape.

Bokeh: Default: 0, Range: any, Shared .
Softens the outer edge of the iris shape, which gives a softer look to the defocused highlights. A negative value darkens the center of the iris shape, producing a ring-like defocus shape.

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

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.

Edge Mode: Popup menu,  Default: Reflect .
Determines the behavior when accessing areas outside the source image.
Black: Areas outside the source image are treated as black, which can produce dark areas around the edges of the image. Select this for fastest rendering.
Repeat: Repeats the last pixel outside the border of the image.
Reflect: Reflects the image outside the border.

Mix With Source: Default: 0, Range: 0 to 1, Shared .
Interpolates between the defocused result and the original source. Set this to 1 for the original source.

Show Shape: Check-box,  Default: off, Shared .
Show the iris shape instead of the defocused image.


Lens Noise: Default: 0, Range: 0 or greater, Shared .
Increase to add noise to the iris shape, dirtying up the defocus a little. Can make the result more realistic. Turn up past 1 for a more stylistic result.

Noise Freq: Default: 40, Range: 0.01 or greater, Shared .
The frequency of the added noise. Ignored if Lens Noise is zero.

Noise Freq Rel X: Default: 1, Range: 0.01 or greater, Shared .
The relative horizontal frequency of the added iris noise. Increase to stretch it vertically or decrease to stretch it horizontally.

Noise Seed: Default: 0.123, Range: 0 or greater, Shared .
The seed value for the added noise. To make the noise appear different on each frame, animate this to be different on each frame. The actual value doesn't matter; only that it's different.


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.
