Optics-2022 : Filters : S_BlurDirectional
S_BlurDirectional
Description
Blurs the image in a given direction using a gaussian, triangle, or box filter.
The S_BlurDirectional filter comes from the Emmy award winning Boris FX Sapphire filter set.
Category
Diffusion/Blurs.
Controls
Presets
To select a preset, pick one from the Presets window.
Blur Amount
Scales the width of the blur.
Angle
The direction of the blur. An angle of 0 produces a horizontal blur and an angle of 90 produces a vertical blur.
Shift
Shifts the image in the direction of the blur. A negative shift amount shifts the image in the opposite direction.
Bias
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.
Blur RGB
Blur Red
The blur width of the red channel relative to Blur Amount.
Blur Green
The blur width of the green channel relative to Blur Amount.
Blur Blue
The blur width of the blue channel relative to Blur Amount.
Shift RGB
Shift Red
Additional amount to shift the red color channel.
Shift Green
Additional amount to shift the green color channel.
Shift Blue
Additional amount to shift the blue color channel.
Brightness
Scales the brightness of the result.
Offset Darks
Adds this gray value to the darker regions of the result. This can be negative to increase contrast.
Mix With Source
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
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.
Edge Mode
Determines the behavior when accessing areas outside the source image.
Transparent
Areas outside the source image are treated as transparent, which can produce transparency 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.
Soft Borders
If enabled, transparent borders are added to the 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.
Show Blur Amount
Enables/disables the on-screen control for adjusting the blur amount parameters.
Show Angle
Enables/disables the on-screen control for adjusting the Angle parameter.
