Blurs 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.
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.
Popup menu, Default: Blur Color.
Selects between full color or monochrome result.
- Blur Color: blurs all the channels of the source input.
- Blur Mono: makes the source monochrome and then blurs
the resulting single channel (faster).
- Blur Amount: Default: 36, Range: 0 or greater.
Scales the width of the blur.
- 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 Opacity: Default: 1, Range: 0 to 10.
Scales the opacity (alpha channel) of the result.
- 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.
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 the Blur Amount or Blur Rel 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.
Popup menu, Default: Normal.
Determines the method used for dealing with
- 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.
