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.
-
Start Color:
Default rgb:
[0 0.8 0.3],
Shared
.
Sets the color at the starting control point.
-
End Color:
Default rgb:
[0.6 0.2 0.8],

.
Sets the color at the ending control point.
-
Start:
X & Y, Default:
[-0.7 0.4],
Range:
any.
The starting point of the Aurora.
-
End:
X & Y, Default:
[0.8 -0.5],
Range:
any.
The ending point of the Aurora.
-
Stroke Size:
Default:
0.25,
Range:
0 or greater,
Shared
.
Influences the width of the Aurora along the spline. This parameter controls the size of the underlying color gradient before it's distorted.
-
Color Phase:
Default:
0,
Range:
0 or greater,
Shared
.
Adjusts the phase of the gradient between Start Color and End Color. Use this to animate the movement of the colors along the Aurora.
-
Brightness:
Default:
0.3,
Range:
0 or greater,
Shared
.
Scales the brightness of the Aurora.
-
Softness:
Default:
0.075,
Range:
0 or greater,
Shared
.
The amount of blur applied to the Aurora. Set to 0 to get a colored point cloud.
-
Softness Rel Y:
Default:
10,
Range:
0 or greater,
Shared
.
The relative vertical amount of softness.
-
Swirl Complexity:
Integer, Default:
3,
Range:
1 or greater,
Shared
.
Specifies how many layers should be rendered in the Aurora. The more layers rendered, the more complex pattern generated along the spline.
-
Swirl Magnitude:
Default:
0.7,
Range:
0 or greater,
Shared
.
The magnitude or amplitude of the swirls along the spline. Setting this to 0 will render a color gradient along the spline.
-
Magnitude Rel Y:
Default:
1.25,
Range:
0 or greater,
Shared
.
The relative vertical magnitude of the swirls.
-
Swirl Frequency:
Default:
2,
Range:
0 to 50,
Shared
.
The frequency of the swirls along the spline.
-
Frequency Rel Y:
Default:
10,
Range:
0 or greater,
Shared
.
The relative vertical frequency along the spline.
-
Swirl Speed X:
Default:
0.1,
Range:
any,
Shared
.
The speed at which the swirls move horizontally.
-
Swirl Speed Y:
Default:
0,
Range:
any,
Shared
.
The speed at which the swirls move vertically.
-
Seed:
Default:
0.123,
Range:
0 or greater,
Shared
.
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.
Params2:
-
Light Brightness:
Default:
1,
Range:
0 or greater,
Shared
.
Lights a circular area of the Aurora. Set to 0 to disable the light. Increase value to increase the intensity of the light.
-
Light Pos:
X & Y, Default:
[-0.3 -0.5],
Range:
any,
Shared
.
The position of the center of the light.
-
Light Color:
Default rgb:
[1 1 1],
Shared
.
The color of the light.
-
Ambient Light:
Default:
1,
Range:
0 or greater,
Shared
.
The level of illumination outside the light.
-
Light Radius:
Default:
1,
Range:
0 or greater,
Shared
.
Distance from the center of the light to the edge of the brightest section.
-
Light Softness:
Default:
2,
Range:
0 or greater,
Shared
.
How quickly the edge of the light should taper off of to darkness.
Params3:
-
Point 1 Enable:
Check-box, Default:
off.
Turns on or off the first control point.
-
Control Point 1:
X & Y, Default:
[-0.33 0.4],
Range:
any.
First spline control point.
-
Point 2 Enable:
Check-box, Default:
on.
Turns on or off the second control point.
-
Control Point 2:
X & Y, Default:
[0.04 0.2],

Second spline control point.
-
Point 3 Enable:
Check-box, Default:
on.
Turns on or off the third control point.
-
Control Point 3:

-
Control Point 4:
X & Y, Default:
[0.45 -0.33],
Range:
any.

-
Bg Brightness:
Default:
1,
Range:
0 or greater,
Shared
.
Scales the brightness of the Background input.
-
Combine:
Popup menu, Default: Screen
.
Determines how the Aurora is combined with the source image.
-
Screen:
the Aurora is blended with the source using a screen operation.
- Add: the Aurora is added to the source.
- Aurora Only: gives the Aurora with no source.
- Add: the Aurora is added to the source.
-
Screen:
the Aurora is blended with the source using a screen operation.
-
Mocha:
Default:
0,
Range:
0 or greater,
Shared
.
Brings up the Mocha window for tracking footage and generating masks.
-
Blur Mocha:
Default:
0,
Range:
0 or greater,
Shared
.
Blurs the Mocha Mask by this amount before using. This can be used to soften the edges or quantization artifacts of the mask, and smooth out the time displacements.
-
Mocha Opacity:
Default:
1,
Range:
0 to 1,
Shared
.
Controls the strength of the Mocha mask. Lower values reduce the intensity of the effect.
-
Invert Mocha:
Check-box, Default:
off,
Shared
.
If enabled, the black and white of the Mocha Mask are inverted before applying the effect.
-
Show Mocha Only:
Check-box, Default:
off,
Shared
.
Bypass the effect and show the Mocha Mask itself.
-
Bypass Mocha:
Check-box, Default:
off,
Shared
.
Ignore the Mocha Mask and apply the effect to the entire source clip.
