Optics-2022 : Filters : S_BlurChannels
S_BlurChannels
Description
Blurs each channel of the image by an arbitrary amount using a gaussian, triangle, or box filter.
The S_BlurChannels 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 for all channels.
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.
Blur Alpha
The blur width of the alpha channel, relative to Blur Amount.
Blur Rel
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
Brightness
Scales the brightness of the result.
Scale Red
Scales the blurred red channel.
Scale Green
Scales the blurred green channel.
Scale Blue
Scales the blurred blue channel.
Scale Alpha
Scales the blurred alpha channel.
Offset
Offset Darks
Adds this gray value to the darker regions of the result. This can be negative to increase contrast.
Offset Red
Adds this value to the red channel of the result.
Offset Green
Adds this value to the green channel of the result.
Offset Blue
Adds this value to the blue channel of the result.
Offset Alpha
Adds this value to the alpha channel of the result.
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.
Subpixel
Enables blurring by subpixel amounts. Use this for smoother animation of any of the blur amount parameters.
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.
