GradientRadialIn the S_Gradient Plugin.Makes a smooth radial color gradient in an ellipse shape, given Center, Inner Radius, and Outer Radius parameters, and optionally combines the gradient with a background clip. Increase Add Noise to reduce banding artifacts in the gradient due to color quantization. Inputs:

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.
-
Center:
X & Y, Default:
[0 0],
Range:
any,
Shared
.
The center location of the ellipse shape. This parameter can be adjusted using the Center Widget.
-
Inner Radius:
Default:
0.2,
Range:
0 or greater,
Shared
.
Distance from the center that the gradient starts. This parameter can be adjusted using the Inner Radius Widget.
-
Outer Radius:
Default:
0.5,
Range:
0 or greater,
Shared
.
Distance from the center that the gradient ends. This parameter can be adjusted using the Outer Radius Widget.
-
Add Noise:
Default:
0,
Range:
0 or greater,
Shared
.
If positive, this amount of noise is added to the gradient. This can create a grainy effect and eliminate banding in the gradient due to quantization. Set this to 1.0 to enable effective debanding for 8 bit results.
-
Smooth Curve:
Default:
0,
Range:
0 to 1,
Shared
.
If zero, a linear interpolation is used across the screen between the Start and End Color. Increase this value to use a smoother 'S' shaped curve for interpolation which can reduce the visual perception of the gradient's Start and End locations.
-
Rel Width:
Default:
1,
Range:
0.1 or greater,
Shared
.
The relative horizontal size of the ellipse shape. Increase for a wider ellipse, decrease for a taller one.
-
Rel Height:
Default:
0.75,
Range:
0.1 or greater,
Shared
.
The relative vertical size of the ellipse shape. Increase for a taller ellipse, decrease for a wider one.
-
Rotate:
Default:
0,
Range:
any,
Shared
.
Rotation in degrees of the ellipse. Note that rotation will have no effect when Rel Width and Rel Height are equal and the shape is a perfect circle. This parameter can be adjusted using the Rotate Widget.
-
Brightness:
Default:
1,
Range:
0 or greater,
Shared
.
Scales the brightness of the gradient image (both the Inner Color and Outer Color).
-
Inner Color:
Default rgb:
[1 1 1],
Shared
.
The gradient color at the Inner Radius.
-
Outer Color:
Default rgb:
[0 0 0],
Shared
.
The gradient color at the Outer Radius.
-
Combine:
Popup menu, Default: Grad Only
.
Determines how the gradient is combined with the background.
-
Grad Only:
gives the gradient image alone with no background.
- Mult: the background is multiplied by the gradient.
- Add: the background is added to the gradient.
- Screen: the background is blended with the gradient using a screen operation.
- Difference: the result is the difference between the background and gradient.
- Overlay: combines gradient and background using an overlay function.
- Mult: the background is multiplied by the gradient.
-
Grad Only:
gives the gradient image alone with no background.
-
Scale Back:
Default:
1,
Range:
0 or greater,
Shared
.
Scales the brightness of the background before combining it with the gradient.
Params2:
Params3:
-
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.
