Sapphire Plug-ins for Autodesk: MatteOpsComp

MatteOpsComp

Grows, shrinks, or adds noise to the edges of a Matte input, then uses the result to composite the Front over the Back.

Inputs:

Front: The clip to use as foreground.

Back: The clip to use as background.

Matte: The matte input clip to process. It is assumed to have anti-aliased but hard edges, because very soft edges might not be affected in a useful way. Only the red channel of this input is used.

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.

Shrink- Grow+: Default: 0, Range: any.
Amount to grow the matte edges in approximate pixels, or shrink if negative.

Edge Softness: Default: 1, Range: 0.01 or greater.
The resulting softness of the edges.

Post Blur: Default: 0, Range: 0 or greater.
If positive, the result is blurred by this amount. This is an alternative method for softening the edges.

Filter: Popup menu,  Default: Triangle .
The type of blur filter to use for the shrink or grow process.
Box: uses a rectangular shaped filter.
Triangle: smoother, uses a pyramid shaped filter.
Gauss: smoothest, uses a gaussian shaped filter.

Invert Matte: Check-box,  Default: off.
If enabled, the black and white of the output matte are inverted.

Noise Amplitude: Default: 0, Range: 0 or greater.
The amount of noise texture to add to the edges.

Noise Width: Default: 0.05, Range: 0 or greater.
The width of the area at the matte edges where the noise is included. This has no effect unless Noise Amplitude is positive

Frequency: Default: 100, Range: 0.1 or greater.
The frequency of the noise. Increase for finer grain noise, decrease for coarser noise. This has no effect unless Noise Amplitude is positive.

Frequency Rel X: Default: 1, Range: 0.01 or greater.
The relative horizontal frequency of the noise. Increase to stretch the noise vertically, decrease to stretch it horizontally. This has no effect unless Noise Amplitude is positive.

Octaves: Integer,  Default: 1, Range: 1 to 10.
The number of summed layers of noise. Each octave is twice the frequency and half the magnitude of the previous. This has no effect unless Noise Amplitude is positive.

Seed: Default: 0.23, Range: 0 or greater.
Used to initialize the random number generator. The actual seed value is not significant, but different seeds give different results and the same value should give a repeatable result.

Noise Shift: X & Y,   Default: [0 0], Range: any.
The horizontal and vertical translation of the noise texture.

Jitter Frames: Integer,  Default: 1, Range: 0 or greater.
If this is 0, the noise texture will remain the same for every frame processed. If it is 1, a new noise texture is used for each frame. If it is 2, a new noise texture is used for every other frame, and so on.

Params3:

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.

Combine Masks: Popup menu,  Default: Union .
Determines how to combine the Mocha Mask and Input Mask when both are supplied to the effect.
Union: Uses the area covered by both masks together.
Intersect: Uses the area that overlaps between the two masks.
Mocha Only: Ignore the Input Mask and only use the Mocha Mask.
