S_BlurChannels Blurs each channel of the source clip by an arbitrary amount using a pseudo-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 current layer.   The clip to be processed. Matte:  Defaults to None.   If provided, the blur is only performed on regions of the source clip specified by the bright areas of this input. Pixels outside this matte are not blurred, and do not contribute to the resulting blurred pixels within it. This input can be affected using the Invert Matte, or Matte Use parameters.

Parameters:

Blur Amount:   Default: 36,  Range: 0 or greater.
Scales the width of the blur for all channels.

Blur Red:   Default: 0,  Range: 0 or greater.
The blur width of the red channel, relative to Blur Amount.

Blur Green:   Default: 0.5,  Range: 0 or greater.
The blur width of the green channel, relative to Blur Amount.

Blur Blue:   Default: 1,  Range: 0 or greater.
The blur width of the blue channel, relative to Blur Amount.

Blur Alpha:   Default: 0,  Range: 0 or greater.
The blur width of the alpha channel if present, relative to Blur Amount.

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.

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.

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.

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

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

Luma:  the luminance of the RGB channels is used.

Alpha:  only the Alpha channel is used.

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.

Opacity:   Popup menu,  Default: Normal.
Determines the method used for dealing with opacity/transparency.

All Opaque:  Use this option to render slightly faster when the input image is fully opaque with no transparency (alpha=1).

Normal:  Process opacity normally.

As Premult:  Process as if the image is already in premultiplied form (colors have been scaled by opacity). This option also renders slightly faster than Normal mode, but the results will also be in premultiplied form, which is sometimes less correct.

Show Blur Amount: Check-box, Default: off.
Turns on or off the screen user interface for adjusting the blur amount parameters.This parameter only appears on AE and Premiere, where on-screen widgets are supported.
