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 Percent parameter should be animated to control the transition speed. In the Sapphire Transitions effects submenu. Inputs: Foreground:  The current layer.   Starts the transition with this clip. Background:  Defaults to None.   Ends the transition with this clip. If this input is not provided, a fully transparent background is used, showing whatever is behind it. Note that the background can not be warped during the transition unless this input is provided.

Parameters:

Transition Dir:   Popup menu,  Default: Dissolve Off to Bg.
Selects the direction of the transition.

Dissolve Off to Bg:  transitions from the current layer to the Background.

Dissolve On from Bg:  transitions from the Background to the current layer.

Auto Trans:   Popup YES-NO,  Default: No.
If enabled, a transition is performed automatically between the first and last frames of the layer. If this is off, the transition is performed manually by animating the Dissolve Percent parameter.

Dissolve Percent:   Default: 0,  Range: 0 to 100.
Auto Trans must be disabled for this parameter to be used. It determines the transition ratio between the Foreground and Background inputs, and would normally be animated from 0 to 100 to perform a complete transition. The curve controlling this parameter can be adjusted for more detailed control over the timing of the dissolve. The Slow In and Slow Out parameters, if positive, also adjust the transition ratio internally for a smoother start and/or end to the 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.

Opacity:   Popup menu,  Default: Normal.
Determines the method used for dealing with opacity/transparency.

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.
