S_DissolveBubble Transitions between two input clips using a bubble warping function. The first clip is warped away and faded out while the second clip is unwarped into place and faded in. The Dissolve Amount parameter should be animated to control the transition speed. In the Sapphire Transitions effects submenu. Inputs: From:  Starts the transition with this clip. To:  Ends the transition with this clip.

Parameters:

Dissolve Amount:   Default: 0,  Range: -0.5 to 1.5.
The transition ratio between the From and To inputs. A value of 0 gives only the From input and a value of 1 gives only the To input. By default this parameter automatically animates from 0 to 1 to perform a complete transition.

Frequency:   Default: 8,  Range: 0.01 or greater.
The frequency of the bubble warping pattern. Increase for smaller bubbles, decrease for larger.

Frequency Rel Y:   Default: 1,  Range: 0.01 or greater.
The relative vertical frequency of the bubbles. Decrease for taller bubbles, increase 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.

Amplitude:   Default: 1,  Range: any.
Scales the amount of warping distortion.

Rel Amp2:   Default: -1,  Range: any.
The relative amplitude of the second input clip warping distortion. If this is positive instead of negative, the clip will be unwarped from the opposite direction.

Slow In:   Default: 0.5,  Range: 0 to 1.
If positive, causes the transition to start more gradually.

Slow Out:   Default: 0.5,  Range: 0 to 1.
If positive, causes the transition to end more gradually.

Wrap:   X & Y,  Popup menu,  Default: [Reflect Reflect].
Determines the method for accessing outside the borders of the source images.

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.
The type of convolution filter to blur with.

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.
