S_BlurChannels Blurs each channel of the source clip by an arbitrary amount using a gaussian, triangle, or box filter. This effect should render quickly even with very large Width values. Use the Blur Rel X and Y parameters for a more horizontal or vertical blur direction. 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 Amount:   Default: 0.1,  Range: 0 or greater.
Scales the width of the blur for all channels. This parameter can be adjusted using the Blur Amount Widget.

Blur Red:   Default: 0,  Range: 0 or greater.
The blur width of the red channel, relative to Blur Amount. This parameter can be adjusted using the Blur Amount Widget.

Blur Green:   Default: 0.5,  Range: 0 or greater.
The blur width of the green channel, relative to Blur Amount. This parameter can be adjusted using the Blur Amount Widget.

Blur Blue:   Default: 1,  Range: 0 or greater.
The blur width of the blue channel, relative to Blur Amount. This parameter can be adjusted using the Blur Amount Widget.

Blur Alpha:   Default: 0,  Range: 0 or greater.
The blur width of the alpha channel if present, relative to Blur Amount. This parameter can be adjusted using the Blur Amount 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 Amount Widget.

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

Scale Red:   Default: 1,  Range: 0 or greater.
Scales the blurred red channel.

Scale Green:   Default: 1,  Range: 0 or greater.
Scales the blurred green channel.

Scale Blue:   Default: 1,  Range: 0 or greater.
Scales the blurred blue channel.

Scale Alpha:   Default: 1,  Range: 0 or greater.
Scales the blurred alpha channel, if present.

Offset Darks:   Default: 0,  Range: -8 to 2.
Adds this gray value to the darker regions of the result. This can be negative to increase contrast.

Offset Red:   Default: 0,  Range: -8 to 2.
Adds this value to the red channel of the result.

Offset Green:   Default: 0,  Range: -8 to 2.
Adds this value to the green channel of the result.

Offset Blue:   Default: 0,  Range: -8 to 2.
Adds this value to the blue channel of the result.

Offset Alpha:   Default: 0,  Range: -8 to 2.
Adds this value to the alpha channel of the result, if present.

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 any of the blur amount parameters.

Soft Borders:   Check-box,  Default: off.
If enabled, transparent borders are added to the input image before processing. This allows the result to include soft edges beyond the original image size. When off, the effect only occurs within the frame and the result will retain an edge at the borders. This parameter does not appear in FCP or DF because those applications don't support image expansion.

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 Amount: Check-box, Default: on.
Turns on or off the screen user interface for adjusting the blur amount parameters.
