BlurMask In the S_BlursMask Plugin. Blurs the source clip by an arbitrary amount using a gaussian, triangle, or box filter. This is similar to Blur, but a Mask input specifies which areas of the source are to be blurred. Inputs: Source:  The clip to be processed. Mask:  The blur is only performed on regions of the source clip specified by the bright areas of this input. Pixels outside this mask are not blurred, and do not contribute to the resulting blurred pixels within it. Only the red channel of this input is used.

Parameters:

Blur Amount:   Default: 0.5,  Range: 0 or greater,  Shared.
Scales the width of the blur. This parameter can be adjusted using the Blur Amount Widget.

Blur Rel:   X & Y,   Default: [1 1],  Range: 0 or greater,  Shared.
The relative horizontal and vertical blur widths. Set Blur Rel X to 0 for a vertical-only blur, or set Blur Rel Y to 0 for a horizontal-only blur. This parameter can be adjusted using the Blur Amount Widget.

Filter:   Popup menu,  Default: GAUSS.
The type of convolution filter to blur with.

BOX:  uses a rectangular shaped filter.

TRIANGLE:  smoother, uses a pyramid shaped filter.

GAUSS:  smoothest, uses a gaussian shaped filter.

Scale Result:   Default: 1,  Range: 0 or greater,  Shared.
Scales the brightness of the result.

Offset Darks:   Default: 0,  Range: any,  Shared.
Adds this gray value to the darker regions of the result. This can be negative to increase contrast.

Subpixel:   Check-box,  Default: off,  Shared.
Enables blurring by subpixel amounts. Use this for smoother animation of the Blur Amount or Blur Rel parameters.

Mix With Source:   Default: 0,  Range: 0 to 1,  Shared.
Interpolates between the blurred result (0) and the original source (1). 0.1 can give a nice misty effect since it mixes only a little of the source in.

Invert Mask:   Check-box,  Default: off.
If enabled, inverts the mask input so the effect is applied to areas where the Mask is black instead of white.
