Warps the source clip by a smooth noise function. This can be used to create
heat diffusion or under water types of effects. The Shift Speed parameters
cause the noise pattern to automatically translate over time. Adjust the
Amplitude and Frequency parameters to give different types of distortions.
In the Sapphire Distort effects submenu.
Source: The current layer. The input clip to be warped.
Matte: Defaults to None. If provided, the amplitude of warping is scaled
by the values of this input clip. Gray values internally scale the
warping amplitude rather than simply cross-fading between the effect
and the original source to allow more continuous results at the
matte edges and more detailed control over the warping amounts.
This input can be affected using the Blur Matte, Invert Matte, or
Matte Use parameters.
- Amplitude: Default: 0.25, Range: any.
Scales the amount of warping distortion. Increase for
more severe distortion.
- Frequency: Default: 16, Range: 0.01 or greater.
The frequency of the noise pattern. Increase for more
and smaller bubbles, decrease for fewer and larger bubbles.
- Frequency Rel X: Default: 1, Range: 0.01 or greater.
The relative horizontal frequency of the bubble
pattern. Increase for taller bubbles, decrease for wider ones.
- Octaves: Integer, Default: 1, Range: 1 to 10.
The number of summed layers of noise. Each octave is twice
the frequency and half the amplitude of the previous. A single octave
gives a smooth texture. Adding octaves makes the result approach a
fractal (1/f) noise texture.
- Seed: Default: 0.23, Range: 0 or greater.
Used to initialize the random number generator. The actual
seed value is not significant, but different seeds give different
results and the same value should give a repeatable result.
- Rotate Warp Dir: Default: 0, Range: any.
Rotation angle of the warping directions in
- Shift Start: X & Y, Default: [0 0], Range: any.
The translation of the bubble pattern.
- Shift Speed: X & Y, Default: [36 0], Range: any.
If non-zero, the bubble pattern is automatically
animated to shift at this speed. The result of animated Speed
values may not be intuitive, so for variable speed motion it is
usually best to set this to 0 and animate the Shift Start values
- Z Dist: Default: 1, Range: 0.001 or greater.
Scales the 'distance' of the image. Values greater than 1.0
move it farther away and make it smaller. Values less then 1.0 move
the image closer and enlarge it. Zooming in slightly can sometimes be
used to hide edge artifacts.
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.
If your image has sharp color changes where the matte
channel also has sharp edges, you may get better results with Normal
