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.
-
Mocha:
Default:
0,
Range:
0 or greater.
Brings up the Mocha window for tracking footage and generating masks.
-
Blur Mocha:
Default:
0,
Range:
0 or greater.
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.
Controls the strength of the Mocha mask. Lower values reduce the intensity of the effect.
-
Invert Mocha:
Check-box, Default:
off.
If enabled, the black and white of the Mocha Mask are inverted before applying the effect.
-
Resize Mocha:
Default:
1,
Range:
0 to 2.
Scales the Mocha Mask. 1.0 is the original size.
-
Resize Rel X:
Default:
1,
Range:
0 to 2.
The relative horizontal size of the Mocha Mask.
-
Resize Rel Y:
Default:
1,
Range:
0 to 2.
The relative vertical size of the Mocha Mask.
-
Shift Mocha:
X & Y, Default:
[0 0],
Range:
any.
Offsets the position of the Mocha Mask.
-
Bypass Mocha:
Check-box, Default:
off.
Ignore the Mocha Mask and apply the effect to the entire source clip.
-
Show Mocha Only:
Check-box, Default:
off.
Bypass the effect and show the Mocha Mask itself.
-
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.
- Intersect: Uses the area that overlaps between the two masks.
-
Union:
Uses the area covered by both masks together.
-
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.
- Triangle: smoother, uses a pyramid shaped filter.
-
Box:
uses a rectangular shaped filter.
-
Matte Use:
Popup menu, Default: Alpha
.
Determines how the Matte input channels are used to make a monochrome matte.
-
Luma:
the luminance of the RGB channels is used.
- Alpha: only the Alpha channel is used, or if there is no valid Alpha channel the Red channel is used.
- Alpha: only the Alpha channel is used, or if there is no valid Alpha channel the Red channel is used.
-
Luma:
the luminance of the RGB channels is used.
-
Invert Matte:
Check-box, Default:
off.
If enabled, the black and white of the output matte are inverted.
-
Output:
Popup menu, Default: Matte
.
Selects the format of the output.
-
Matte:
the processed Matte is output on all channels.
- RGBA: the Alpha output channel receives the processed Matte, and the RGB channels are passed through from the input unchanged.
- RGBA Premult: the Alpha output channel receives the processed Matte, and the RGB channels receive the input multiplied by the new Matte. This option can be appropriate if you are shrinking a matte and need an RGBA result for pre-multiplied compositing.
- RGBA: the Alpha output channel receives the processed Matte, and the RGB channels are passed through from the input unchanged.
-
Matte:
the processed Matte is output on all channels.
-
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.
