Sapphire Plug-ins for Open Fx: WipeBubble

S_WipeBubble

Wipes between two input clips with a bubble-warp process performed within the transition area. The Wipe Amount parameter should be animated to control the transition speed.

In the Sapphire Transitions effects submenu.


Inputs:

From: Optional. Starts the transition with this clip.

To: Optional. Ends the transition with this clip.

Parameters:

Load Preset: Push-button .
Brings up the Preset Browser to browse all available presets for this effect.

Save Preset: Push-button .
Brings up the Preset Save dialog to save a preset for this effect.

Wipe Amount: Default: 0, Range: -0.5 to 1.5.
Determines the transition ratio between the From and To inputs, and would normally be animated from 0 to 1 to perform a complete transition. The curve controlling this parameter can be adjusted for more detailed control over the timing of the wipe.

Edge Width: Default: 1.4, Range: 0.014 or greater.
The width of the transition area. This can be adjusted using the Wipe Widget.

Angle: Default: 0, Range: any.
The angle of the wipe direction in counter-clockwise degrees from the right. This can be adjusted using the Wipe Widget.

Bubble Amount: Default: 0.5, Range: 0 or greater.
The magnitude of the bubble distortion.

Frequency: Default: 8, Range: 0.1 or greater.
The frequency of the bubble pattern. Increase to zoom out, decrease to zoom in.

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 bubbles.

Octaves: Integer,  Default: 8, 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.

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.

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.

Show Wipe: Check-box, Default: on.
Turns on or off the screen user interface widget for adjusting the Wipe Amt, Angle, and Edge Width parameters.
