BlurChromaMask In the S_BlursMask Plugin. Separates the source into luminance and chrominance components, blurs the chrominance and/or the luminance independently, and recombines them. Similar to BlurChroma, 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 Chroma:   Default: 0.5,  Range: 0 or greater.
The amount to blur the chrominance. This parameter can be adjusted using the Blur Chroma Widget.

Blur Luminance:   Default: 0,  Range: 0 or greater.
The amount to blur the luminance. This parameter can be adjusted using the Blur Luma Widget.

Blur Rel:   X & Y,   Default: [1 1],  Range: 0 or greater.
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 Chroma 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 Chroma:   Default: 1,  Range: 0 or greater.
Scales the chrominance by this amount. Increase for more intense colors, decrease for muted colors.

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

Offset Result:   Default: 0,  Range: any.
Adds this gray value to the result (or subtracts if negative). 0 has no effect, .5 is middle gray, and 1 is white.

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