Overview
The BCC Vignette filter provides a convenient way to darken and / or blur the outer region of the input clip. Built-in controls allow for the vignette shape to be anything between an oval and a square, with hard or completely smooth feathered edges and the built-in apply modes offer the ability to generate truly unique and interesting vignette effects.
Function
Presets and Common Controls
BCC filters come with a library of factory installed presets plus the ability to create your own custom presets and preview them with the BCC FX Browser™.
BCC filters also include common controls that configure global effect preferences and other host-specific effect settings.

Load / Save Preset Mechanism
The built-in load save mechanism is used to access the factory installed or user generated presets.
Center: Controls set the center point of the vignette geometry.
Style: Controls whether the filter produces a color vignette, a blur vignette, or both.
Radius: Controls the overall size of the vignette shape.
Vignette Color: Controls the color of the vignette region.
Vignette Color Opacity: Controls the opacity of the colored vignette region. Higher opacities produce solid vignette colors as you progress to the outer regions of the vignette, whereas lower opacities allow for more subtle, partial color shifts.
Blur Offset: Controls the relative radius of the blur vignette versus the radius of the color vignette (when the Style is set to Color and Blur). At the default value of zero the color and blur vignette regions have the same size (as determined by the shared Radius control). Larger values cause the blur vignette radius to be proportionally larger than the color vignette radius, whereas negative values cause the blur vignette radius to be proportionally smaller than the color vignette radius.
Blur Amount: Defines the peak blurriness amount as you reach the outer regions of the vignette.
Squareness: Controls whether the vignette shape is elliptical, rectangular, or somewhere in between.
Softness: Softens the edges of the vignette shape.
**Smooth Softness:**For a given Softness, this controls the smoothness of the transition between the inside and outside regions, with higher values producing smoother, more natural looking gradations.
Stretch: Controls the relative width vs height of the vignette shape.
Rotate: Rotates the shape.
Source Intensity: Controls the brightness of the vignette shape.
Combine: Popup menu which determines the blend mode used to apply the color vignette back onto the original source layer. (Not relevant for the blur vignette.)
