WarpBubbleMask In the S_WarpsMask Plugin. 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. Inputs: Source:  The input clip to be warped. Mask:  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 Mask edges and more detailed control over the warping amounts. Only the red channel of this input is used. This input can optionally be blurred or inverted using the Blur Mask or Invert Mask parameters.

Parameters:

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.

Amplitude:   Default: 0.25,  Range: any.
Scales the amount of warping distortion. Increase for more severe distortion.

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.

Shift Start:   X & Y,   Default: [0 0],  Range: any.
The translation of the bubble pattern.

Shift Speed:   X & Y,   Default: [0.1 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 instead.

Z Dist:   Default: 1,  Range: 0.01 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.

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.

Rotate Warp Dir:   Default: 0,  Range: any.
Rotation angle of the warping directions in counter-clockwise degrees.

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.

Blur Mask:   Default: 0,  Range: 0 or greater,  Shared.
Blurs the Mask input by this amount before using. This can provide a smoother transition between the masked and unmasked areas.

Invert Mask:   Check-box,  Default: off,  Shared.
If enabled, inverts the mask input so the effect is applied to areas where the Mask is black instead of white.
