Blurs the source input clip in the direction of the gradient of the Lens input clip. It is best demonstrated when the lens image contains just a few simple shapes.

In the Sapphire Distort effects submenu.


Source:  The current layer.   The clip to be processed.

Lens:  Defaults to None.   Distorts the source using the brightness values of this input clip.

Matte:  Defaults to None.   If provided, the amount of lens distortion is scaled by this input, so the Source is unaffected where the Matte is black. This input can be affected using the Blur Matte, Invert Matte, or Matte Use parameters.


Blur Amount:   Default: 1,  Range: 0 or greater.
The magnitude of the blur distortions.

Warp Amount:   Default: 0,  Range: any.
Adds some additional non-blurred lens distortion if non-zero.

Blur Lens:   Default: 36,  Range: 0 or greater.
Smooths out the edges in the lens image by this amount before using it.

Rotate Blur Dir:   Default: 0,  Range: any.
Rotates the blurring direction by this many degrees. If non-zero, this can add some unusual twisting effects to the blurring.

Wrap:   X & Y,  Popup menu,  Default: [Reflect Reflect].
Determines the method for accessing outside the borders of the source image.
No:  gives black beyond the borders.
Tile:  repeats a copy of the image.
Reflect:  repeats a mirrored copy. Edges are often less visible with this method.

Subpixel:   Check-box,  Default: on.
If enabled, uses a better quality but slightly slower method for performing the blur.

Blur Matte:   Default: 0,  Range: 0 or greater.
Blurs the Matte input by this amount before using. This can provide a smoother transition between the matted and unmatted areas. It has no effect unless the Matte input is provided.

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.

Opacity:   Popup menu,  Default: Normal.
Determines the method used for dealing with opacity/transparency.
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.
