S_WipeBlobs Performs a wipe transition between two input clips using a pattern of blobs generated by a noise function. The Wipe Percent parameter should be animated to control the transition speed. Increase the Grad Add parameter to make the timing of the blobs pattern move across the screen during the wipe. Increase the Border Width parameter to draw a border at the wipe transition edges. 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.

Parameters:

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

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

Wipe 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 Wipe Percent parameter.

Wipe 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 From and To 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 wipe.

Edge Softness:   Default: 0,  Range: 0 or greater.
The width of the transition edges. Larger values will cause softer, less visible edges in the wipe pattern.

Frequency:   Default: 6,  Range: 0.1 or greater.
The frequency of the blobs pattern. Increase for more and smaller blobs, or decrease for fewer and larger.

Rel Width:   Default: 1,  Range: 0.1 or greater.
The relative horizontal size of the blobs. Increase for wider blobs, decrease for taller 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: 0.432,  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:   X & Y,   Default: [360 243],  Range: any.
Translation of the blobs pattern.

Grad Add:   Default: 0,  Range: -10 to 10.
If positive, a gradient will be added to the timing of the transition pattern so it moves across the screen during the wipe. This parameter can be adjusted using the Wipe Widget if enabled, but the value must be positive to make this widget visible.

Grad Angle:   Default: 0,  Range: any.
The direction of the wipe gradient in degrees. This will have no effect unless Grad Add is positive. The Wipe Widget also allows adjusting this parameter.

Border Width:   Default: 0,  Range: 0 or greater.
If positive, a colored border is drawn at the wipe transition edges, using the border color, opacity, softness, and shift parameters below.

Border Color:   Default rgb: [0.75 0 0].
The color of the border. This has no effect unless Border Width is positive.

Border Opacity:   Default: 1,  Range: 0 to 1.
The opacity of the border. Decrease to make the border transparent and allow the image under it to show through. This has no effect unless Border Width is positive.

Border Softness:   Default: 0,  Range: 0 or greater.
The softness of the border edges. This has no effect unless Border Width is positive.

Border Shift:   Default: 0,  Range: any.
Shifts the border ahead of or behind the transition edge. This has no effect unless Border Width is positive.

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.

Show Wipe: Check-box, Default: off.
Turns on or off the screen user interface widget for adjusting the Grad Add, Grad Angle, and Wipe Percent parameters. The value of the Grad Add parameter must first be positive for this widget to be visible.This parameter only appears on AE and Premiere, where on-screen widgets are supported.
