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.
-
Mode:
Popup menu, Default: Vignette
.
Selects between several variations on generating the Vignette shape.
-
Vignette:
The Vignette shape and location are defined by specific parameters.
- VignetteMocha: The Vignette shape and location are defined using a Mocha Mask.
- VignetteMocha: The Vignette shape and location are defined using a Mocha Mask.
-
Vignette:
The Vignette shape and location are defined by specific parameters.
-
Center:
X & Y, Default:
screen center.
The center location of the vignette effect.
-
Squareness:
Default:
0,
Range:
0 to 1.
Determines how square the vignette shape is. Set to 1.0 for a square or rectangle shape. Set to 0 for a circle or ellipse. Values in between give rectangles with rounded corners by varying amounts.
-
Radius:
Default:
0.9,
Range:
0 or greater.
Distance from the center to apply the vignette. This parameter can be adjusted using the Radius Widget.
-
Rel Height:
Default:
0.75,
Range:
0.05 or greater.
The relative vertical size of the vignette shape. Increase for a taller shape, decrease for a wider one.
-
Rel Width:
Default:
1,
Range:
0.05 or greater.
The relative horizontal size of the vignette shape. Increase for a wider shape, decrease for a taller one.
-
Rotate:
Default:
0,
Range:
any.
Rotation in degrees of the vignette shape. Note that rotation will have no effect if Squareness is zero, and Rel Width and Rel Height are equal. This parameter can be adjusted using the Rotate Widget.
-
Mocha:
Default:
0,
Range:
0 or greater.
Brings up the Mocha window for tracking footage and generating masks.
-
Blur Mocha:
Default:
0,
Range:
any.
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 or greater.
Scales the Mocha Mask. 1.0 is the original size.
-
Resize Rel X:
Default:
1,
Range:
0 or greater.
The relative horizontal size of the Mocha Mask.
-
Resize Rel Y:
Default:
1,
Range:
0 or greater.
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.
-
Edge Softness:
Default:
1,
Range:
0 or greater.
The width of the vignette's soft edge. Larger values give softer, less visible edges.
-
Smooth Curve:
Default:
0.4,
Range:
0 to 1.
If zero, a linear gradient is used across the screen in the soft edge area. Increase this value to use a smoother 'S' shaped curve for interpolation which can reduce the visual perception of the gradient's start and end locations.
-
Color:
Default rgb:
[0 0 0].
The color of the vignette.
-
Opacity:
Default:
1,
Range:
0 or greater.
The opacity of the vignette; animate to 0 to fade the vignette out.
-
Blur Amount:
Default:
0,
Range:
any.
Blurs the borders of the image in addition to darkening them.
-
Blur Inside:
Check-box, Default:
off.
If checked, the center (undarkened) area of the image is blurred instead of the border.
-
Source Brightness:
Default:
1,
Range:
0 or greater.
Scales the brightness of the source clip. To see only the vignette, set this to zero.
-
Combine:
Popup menu, Default: Composite
.
Determines how the vignette is combined with the Source.
-
Composite:
composites the vignette over the source clip.
- Mult: the vignette color is multiplied by the source clip. If the Color is not black, this will selectively colorize the vignette area.
- Add: the vignette color is added to the source clip. This will have no effect if the vignette color is black.
- Screen: the vignette color is combined with the source clip using a screen operation. This will have no effect if the vignette color is black.
- Subtract Inv: the inverse of the vignette color is subtracted from the source clip. Inverse means white for black, yellow for blue, and so on. This mode looks similar to Mult, but a bit more severe; it crushes the blacks and leaves the highlights more. This will have no effect if the vignette color is white.
- Vignette Only: shows the vignette pattern without the source clip. The output will be white where the amount of vignetting is greatest (e.g. where the source clip would be darkened completely).
- Vignette Only Inv: shows the inverted vignette pattern without the source clip. The output will be white where there is no vignetting (e.g. where the source clip would not be darkened at all).
- Mult: the vignette color is multiplied by the source clip. If the Color is not black, this will selectively colorize the vignette area.
-
Composite:
composites the vignette over the source clip.
