S_WipeCloudsTransitions from the first clip to the second using a moving cloud texture. The Wipe Amount parameter should be animated to control the transition speed.In the Sapphire Transitions effects submenu.

-
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.
-
Frequency:
Default:
2,
Range:
0.1 or greater.
The frequency of the clouds pattern. Increase for more and smaller elements, or decrease for fewer and larger.
-
Frequency Rel X:
Default:
0.4,
Range:
0.01 or greater.
The relative horizontal frequency of the texture. Increase to stretch it vertically or decrease to stretch it horizontally.
-
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.
-
Shift Start:
X & Y, Default:
[0 0],
Range:
any.
Translation offset of the texture. Since the texture is procedurally generated it can be shifted with no repeating units or seams occurring.
-
Shift Speed:
X & Y, Default:
[2 0],
Range:
any.
Translation speed of the texture. If non-zero, the result is automatically animated to shift at this rate. The result of animated Speed values may not be intuitive, so for variable speed motion it is usually best to set this to 0 and animate the Shift Start values instead.
-
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.
-
Show Wipe:
Check-box, Default:
on.
Turns on or off the screen user interface for adjusting the Wipe Amount parameter.
-
Show Shift Start:
Check-box, Default:
on.
Turns on or off the screen user interface for adjusting the Shift Start parameter.
