Controls
Presets
To select a preset, pick one from the Presets window.
Center
The center location of the vignette effect.
Squareness
Determines how square the vignette shape is. Set to 1 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
Distance from the center to apply the vignette.
Rel Height
The relative vertical size of the vignette shape. Increase for a taller shape or decrease for a wider one.
Rel Width
The relative horizontal size of the vignette shape. Increase for a wider shape or decrease for a taller one.
Rotate
Rotation in degrees of the vignette shape. Note that rotation will have no effect if Squareness is 0 and Rel Width and Rel Height are equal.
Edge Softness
The width of the vignette's soft edge. Larger values give softer, less visible edges.
Smooth Curve
If 0, 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
The color of the vignette.
Opacity
The opacity of the vignette.
Blur Amount
Blurs the borders of the image in addition to darkening them.
Blur Inside
If checked, the center (undarkened) area of the image is blurred instead of the border.
Source Brightness
Scales the brightness of the source clip. To see only the vignette, set this to zero.
Combine
Determines how the vignette is combined with the image.
Composite
Composites the vignette over the image.
Mult
The vignette color is multiplied by the image. If the Color is not black, this will selectively colorize the vignette area.
Add
The vignette color is added to the image. This will have no effect if the vignette color is black.
Screen
The vignette color is combined with the image 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 image. Inverse means white for black, yellow for blue, and so on. This mode looks similar to Mult, but is a bit more severe. It crushes the blacks and retains the highlights. This will have no effect if the vignette color is white.
Vignette Only
Shows the vignette pattern without the image. The output will be white where the amount of vignetting is greatest, in other words, where the image would be darkened completely.
Vignette Only Inv
Shows the inverted vignette pattern without the image. The output will be white where there is no vignetting, in other words, where the source clip would not be darkened at all.
Show Radius
Enables/disables the on-screen control for adjusting the Radius parameter.
Show Rotate
Enables/disables the on-screen control for adjusting the Rotate parameter.
Show Center
Enables/disables the on-screen control for adjusting the Center parameter.
