Blurs areas of the source clip by different amounts
using depth values from a ZBuffer input. Separates the input into a
number of layers between Z Near and Z Far and blurs them by
different amounts depending on Blur Near and Blur Far. Linear fog
can also be mixed into the result.
In the Sapphire Blur+Sharpen effects submenu.
Source: The current layer. The clip to be processed.
ZBuffer: Defaults to None. The input clip containing depth values for each Source
pixel. These values should be in the range of black to white.
Normally black corresponds to the nearest objects and white to the
- Layer Mode:
Popup menu, Default: Interp.
Determines how the differently blurred layers are combined.
- Comp: the closer layers are composited over the farther
layers. This method often gives better results if you have objects
at different depths overlapping each other with discontinuous values
in your depth image. However, the seams between layers are
sometimes visible with this option.
- Interp: the blurred layers are interpolated using depth
image values. This method gives smoother transitions between
layers, and is usually better if there are no sharp changes in your
- Z Near: Default: 0.33, Range: 0 to 1.
The value of the input Z corresponding to near objects.
Z values less than this will be blurred by Blur Near.
- Z Far: Default: 0.66, Range: 0 to 1.
The value of the input Z corresponding to far objects.
Z values greater than this will be blurred by Blur Far.
- Layers: Integer, Default: 3, Range: 2 to 50.
The number of depth layers to separate the source
into. More layers require more processing but are sometimes needed
to avoid visible seams between the layers blurred by different
- Blur Near: Default: 0, Range: any.
The amount to blur the layer at Z Near.
- Blur Far: Default: 36, Range: any.
The amount to blur the layer at Z Far. Setting either
Blur Near or Blur Far to a negative value causes the interpolated
blur amounts to be zero between Z Near and Z Far, as if the focal
plane were inbetween those depths.
- 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.
- Fog Color: Default rgb: [0.5 0.5 0.5].
The fog color should normally match the sky or
background color of the source clip. Use gray for mist, brown for
smog, blue for underwater, etc.
- Fog Near: Default: 0, Range: 0 to 1.
The amount of fog to add to objects at or closer than Z Near.
- Fog Far: Default: 0, Range: 0 to 1.
The amount of fog to add to objects at or farther than Z Far.
- Zbuffer Use:
Popup menu, Default: Luma.
Determines how the ZBuffer input channels make a monochrome z image.
- 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.
