Warps the source input clip using the gradient of the
Lens input clip. This can generate optical glass-like effects as if
the source clip were being viewed through an arbitrarily shaped
lens. It is best demonstrated when the lens image contains just a
few bold shapes or a simple texture.
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
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
- Amount: Default: 1, Range: any.
The severity of the lens distortions. Make negative to
invert the direction of the distortions.
- Fine: Check-box, Default: off.
If enabled, the warping amount is reduced by a factor of
100. This mode is meant to allow subtle expansion or contraction of
the source image near the edges of its matte given as the Lens input.
- Blur Lens: Default: 36, Range: 0 or greater.
Smooths out the edges in the lens image by this amount
before using it.
- Rotate Warp Dir: Default: 0, Range: any.
Rotates the warping direction by this many
degrees. If non-zero, this can add some unusual twisting effects to
the lens distortion.
X & Y, Popup menu, Default: [Reflect Reflect].
Determines the method for accessing outside the borders of the
- 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.
- Filter: Check-box, Default: on.
If enabled, the image is adaptively filtered when it is
resampled. This gives a better quality result when parts of the image
are warped smaller.
- 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.
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.
