Sapphire Plug-ins for Autodesk: RackDfComp3

RackDfComp3

Composites the Foreground, Middle, and Background while defocusing each layer by different amounts. The Foreground alpha channel is used as the matte.

Inputs:

Front: The clip to use as foreground.

Back: The clip to use as background.

Matte: Specifies the opacities of the Front clip. Only the red channel of this input is used.

Middle: The clip to composite between the Foreground and Background.

MidMatte: The alpha channel of this input specifies the opacities of the Middle input. This input can be affected by the Invert Mattes parameter.

Parameters:

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 Front: Default: 0.1, Range: 0 or greater.
The amount to defocus the Foreground and its Matte. This parameter can be adjusted using the Fg Defocus Widget.

Defocus Middle: Default: 0.05, Range: 0 or greater.
The amount to defocus the Middle and its Matte. This parameter can be adjusted using the Mid Defocus Widget.

Defocus Back: Default: 0, Range: 0 or greater.
The amount to defocus the Background. This parameter can be adjusted using the Bg Defocus Widget.

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

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

Matte Gamma: Default: 1, Range: 0.1 or greater.
The gamma value to use for the defocus of the Matte.

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.
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.
Rotates the iris shape.

Bokeh: Default: 0, Range: any.
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.

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

Comp Premult: Check-box,  Default: off.
Enable this for a better composite if the Foreground pixel values have been pre-multiplied by the Matte pixel values. This is also known as an 'additive' composite.

Invert Mattes: Check-box,  Default: off.
If enabled, the black and white of the matte are inverted before use.

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.

Params2:

Lens Noise: Default: 0, Range: 0 or greater.
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.
The frequency of the added noise. Ignored if Lens Noise is zero.

Noise Freq Rel X: Default: 1, Range: 0.01 or greater.
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.
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.
