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.
-
Color Scale:
Default rgb:
[1 1 1].
Scales the color of the grain by this value. The grain will include both positive and negative values of this color.
-
Color Amplitude:
Default:
0.1,
Range:
0 or greater.
The amplitude of color grain to include.
-
Color Frequency:
Default:
100,
Range:
0.01 or greater.
The frequency of the color grain. Increase for finer color grain, decrease for coarser color grain.
-
Red Freq:
Default:
1,
Range:
0 or greater.
The relative frequency of the red channel grain.
-
Green Freq:
Default:
1,
Range:
0 or greater.
The relative frequency of the green channel grain.
-
Blue Freq:
Default:
1,
Range:
0 or greater.
The relative frequency of the blue channel grain.
-
Color Octaves:
Integer, Default:
1,
Range:
1 to 10.
The number of octaves of color grain to include. Each octave is twice the frequency and half the amplitude of the previous.
-
Bw Amplitude:
Default:
0.05,
Range:
0 or greater.
The amplitude of black and white grain to include.
-
Bw Frequency:
Default:
100,
Range:
0.01 or greater.
The frequency of the black and white grain. Increase for finer grain, decrease for coarser grain.
-
Bw Octaves:
Integer, Default:
1,
Range:
1 to 10.
The number of octaves of black and white grain to include. Each octave is twice the frequency and half the amplitude of the previous.
-
Seed:
Default:
0.123,
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.
-
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.
-
Mask Use:
Popup menu, Default: Luma
.
Determines how the Mask input channels are used to make a monochrome mask.
-
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.
-
Blur Mask:
Default:
0.05,
Range:
0 or greater.
Blurs the Mask input by this amount before using. This can provide a smoother transition between the masked and unmasked areas. It has no effect unless the Mask input is provided.
-
Invert Mask:
Check-box, Default:
off.
If on, inverts the mask input so the effect is applied to areas where the Mask is black instead of white. This has no effect unless the Mask input is provided.
