S_WarpBubble2 Warps the source clip using two overlapping sets of bubble patterns. 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. Inputs: Source:  The input clip to be warped. Mask:  Optional.   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 mask edges and more detailed control over the warping amounts. This input can be affected using the Blur Mask, Invert Mask, or Mask Use parameters.

A Bubble Parameters:

A Amplitude:   Default: 0.25,  Range: any.
The distortion amplitude of the first set of bubbles.

A Frequency:   Default: 4,  Range: 0.01 or greater.
The frequency of the first set of bubbles.

A Octaves:   Integer,  Default: 1,  Range: 1 to 10.
The number of noise octaves of the first set of bubbles.

A Seed:   Default: 0.23,  Range: 0 or greater.
The random number generator seed of the first set of bubbles.

A Shift Start:   X & Y,   Default: [0 0],  Range: any.
The translation of the first set of bubbles.

A Speed:   X & Y,   Default: [0.1 0],  Range: any.
Automatically animated shift for the first set of bubbles.

B Bubble Parameters:

B Amplitude:   Default: 0.25,  Range: any.
The distortion amplitude of the second set of bubbles.

B Frequency:   Default: 4,  Range: 0.01 or greater.
The frequency of the second set of bubbles.

B Octaves:   Integer,  Default: 1,  Range: 1 to 10.
The number of noise octaves of the second set of bubbles.

B Seed:   Default: 0.34,  Range: 0 or greater.
The random number generator seed of the second set of bubbles.

B Shift Start:   X & Y,   Default: [0 0],  Range: any.
The translation of the second set of bubbles.

B Speed:   X & Y,   Default: [-0.1 0],  Range: any.
Automatically animated shift for the second set of bubbles.

Other Parameters:

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.

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.

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

Invert Mask:   Check-box,  Default: off.
If on, inverts the mask input so the effect is applied to areas where the Mask is black instead of white. This has no effect unless the Mask input is provided.

Mask Use:   Popup menu,  Default: Luma.
Determines how the Mask input channels are used to make a monochrome mask.

Luma:  the luminance of the RGB channels is used.

Alpha:  only the Alpha channel is used.

Crop Input Parameters:   Default: 0,  Range: 0 or greater.
These 4 parameters, Crop Top, Crop Bottom, Crop Left, and Crop Right, allow selecting a rectangular subsection of the input image to be processed. If the Wrap parameters are set to "No" the exposed borders will be transparent. If the Wrap is "Tile" or "Reflect" the source image is wrapped on the new cropped borders to fill the frame. This can make it easier to avoid artifacts due to distorting an image with bad edges.
