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 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.
- 3 sides: triangle.
-
Circle:
round.
-
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 Matte:
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.
- 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.
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.
