Range:
0 or greater.
Brings up the Mocha window for tracking footage and generating masks.
-
Blur Mocha:
Default:
0,
Range:
any.

-
Mocha Opacity:
Default:
1,
Range:
0 to 1.
Controls the strength of the Mocha mask. Lower values reduce the intensity of the effect.

Range:
0 to 2.
Scales the Mocha Mask. 1.0 is the original size.
-
Resize Rel X:
Default:

Range:
0 to 2.
The relative horizontal size of the Mocha Mask.
-
Resize Rel Y:
Default:
1,
Range:

The relative vertical size of the Mocha Mask.
-
Shift Mocha:
X & Y, Default:
screen center.
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.
-
Defocus Width:
Default:
0.1,
Range:
any.
The width of the defocus. This parameter can be adjusted using the Defocus Width 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.
Lens Parameters:
-
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.
- 3 sides: triangle.
-
Circle:
round.
-
Show Shape:
Check-box, Default:
off.
Show the iris shape instead of the defocused image.
-
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.
-
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.
Other Parameters:
-
Gauss Blur:
Default:
0,
Range:
any.
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.
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.
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.
-
Highlight 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.
-
Brightness:
Default:
1,
Range:
0 or greater.
Scales the brightness of the result.
-
Offset Darks:
Default:
0,
Range:
any.
Adds this gray value to the darker regions of the result. This can be negative to increase contrast.
-
Scale Color:
Default rgb:
[1 1 1].
Scales the color of the result. For example, if it is yellow [1 1 0], the blue of the result will be 0.
-
Chroma Sep:
Default:
0.3,
Range:
-1 to 1.
The amount of separation between the three color channel rings.
-
Chroma Ringthick:
Default:
0.3,
Range:
0.01 or greater.
The thickness of each of the three color channel rings.
-
Chroma Distort:
Default:
0,
Range:
any.
Adds some chromatic aberration around the edges of the image; red and blue wavelengths of light refract differently in real lenses, producing fringes of color where the rays strike the lens at oblique angles.
-
Mix With Source:
Default:
0,
Range:
0 to 1.
Interpolates between the defocused result and the original source. Set this to 1 for the original source.
-
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.
- Repeat: Repeats the last pixel outside the border of the 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.
-
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:
any.
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.
