S_WipeBlobsPerforms a wipe transition between two input clips using a pattern of blobs generated by a noise function. The Wipe Amount 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.

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 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 elements, or decrease for fewer and larger.
-
Rel Width:
Default:
1,
Range:
0.01 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:
[0 0],
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 counter-clockwise 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.
-
Border Glow:
Default:
0,
Range:
0 or greater.
Adds a glow along the border of the wipe. The value determines the brightness of the glow.
-
Glow Width:
Default:
0.1,
Range:
0 or greater.
The width of the glowing border.
-
Width Red:
Default:
1,
Range:
0 or greater.
Scales the red glow width. If the red, green, and blue widths are all equal, the glow will match Glow Color. Otherwise it will have a fringe of varying color.
-
Width Green:
Default:
1.2,
Range:
0 or greater.
Scales the green glow width.
-
Width Blue:
Default:
1.4,
Range:
0 or greater.
Scales the blue glow width.
-
Glow Color:
Default rgb:
[1 1 1].
The color of the glowing border.
-
Noise Amp:
Default:
1,
Range:
0 or greater.
The amount of noise to add to the glowing border.
-
Noise Freq:
Default:
16,
Range:
0.1 to 20.
The spatial frequency of the noise.
-
Noise Speed:
Default:
2,
Range:
any.
The speed with which the noise changes or boils over time.
