S_BlurChroma Separates the source into luminance and chrominance components, blurs the chrominance and/or the luminance independently, and recombines them. You can also scale the luma and chroma independently to enhance or remove either. In the Sapphire Blur+Sharpen effects submenu. Inputs: Source:  The clip to be processed. Mask:  Optional.   If provided, 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. This input can be affected using the Invert Mask, or Mask Use parameters.

Parameters:

Blur Chroma:   Default: 0.1,  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 Luminance 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.

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: -8 to 2.
Adds this gray value to the result (or subtracts if negative). 0 has no effect, .5 is middle gray, and 1 is white.

Mix With Source:   Default: 0,  Range: 0 to 1.
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.

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.

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

Invert Mask:   Check-box,  Default: off.
If on, inverts the mask input so the effect is applied to areas where the Mask is black instead of white. This has no effect unless the Mask input is provided.

Mask Use:   Popup menu,  Default: Luma.
Determines how the Mask input channels are used to make a monochrome mask.

Luma:  the luminance of the RGB channels is used.

Alpha:  only the Alpha channel is used.

Show Blur Chroma: Check-box, Default: on.
Turns on or off the screen user interface for adjusting the Blur Chroma parameter.

Show Blur Luminance: Check-box, Default: on.
Turns on or off the screen user interface for adjusting the Blur Luminance parameter.
