BlurDirectionalMask In the S_BlursMask Plugin. Blurs the source clip in a single direction using a gaussian, triangle, or box filter. It can also blur each channel by different amounts. Similar to BlurDirectional, 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:

Load Preset: Push-button .
Brings up the Preset Browser to browse all available presets for this effect.

Save Preset: Push-button .
Brings up the Preset Save dialog to save a preset for this effect.

Angle: Default: 45, Range: any.
The direction of the blur. An angle of 0 produces a horizontal blur, and an angle of 90 produces a vertical blur. This parameter can be adjusted using the Angle Widget.

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

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

Blur Green: Default: 1, 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.

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.

Bias: Default: 0.5, Range: 0 to 1.
Varies the weight of the pixels along the path of the blur, which gives the appearance of trails or streaks in a single direction. A value of 0.5 weights all pixels evenly. A value of 1 causes the weight to increase toward the direction of the blur, while a value of 0 has the opposite effect.

Shift: Default: 0, Range: any.
Shifts the image in the direction of the blur. A negative shift amount shifts the image in the opposite direction.

Shift Red: Default: 0, Range: any.
Additional amount to shift the red color channel.

Shift Green: Default: 0, Range: any.
Additional amount to shift the green color channel.

Shift Blue: Default: 0, Range: any.
Additional amount to shift the blue color channel.

Edge Mode: Popup menu,  Default: REFLECT .
Determines the behavior when accessing areas outside the source image.

BLACK: Areas outside the source image are treated as black, which can produce dark areas around the edges of the image. Select this for fastest rendering.

REPEAT: Repeats the last pixel outside the border of the image.

REFLECT: Reflects the image outside the border.

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

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

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.

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

Params2:

Params3:

Mocha: Default: 0, Range: 0 or greater, Shared .
Brings up the Mocha window for tracking footage and generating masks.

Blur Mocha: Default: 0, Range: 0 or greater, Shared .
Blurs the Mocha Mask by this amount before using. This can be used to soften the edges or quantization artifacts of the mask, and smooth out the time displacements.

Mocha Opacity: Default: 1, Range: 0 to 1, Shared .
Controls the strength of the Mocha mask. Lower values reduce the intensity of the effect.

Invert Mocha: Check-box,  Default: off, Shared .
If enabled, the black and white of the Mocha Mask are inverted before applying the effect.

Show Mocha Only: Check-box,  Default: off, Shared .
Bypass the effect and show the Mocha Mask itself.

Bypass Mocha: Check-box,  Default: off, Shared .
Ignore the Mocha Mask and apply the effect to the entire source clip.

Combine Masks: Popup menu,  Default: Union .
Determines how to combine the Mocha Mask and Input Mask when both are supplied to the effect.

Union: Uses the area covered by both masks together.

Intersect: Uses the area that overlaps between the two masks.

Mocha Only: Ignore the Input Mask and only use the Mocha Mask.
