GradientIn the S_Gradient Plugin.Makes a smooth color gradient across the screen using given Start and End locations and colors, then 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.
-
Start:
X & Y, Default:
[0 0.75],
Range:
any,
Shared
.
The starting location of the gradient. This parameter can be adjusted using the Start Widget.
-
End:
X & Y, Default:
[0 -0.75],
Range:
any,
Shared
.
The ending location of the gradient. This parameter can be adjusted using the End 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.
-
Screen Shift:
X & Y, Default:
[0 0],
Range:
any,
Shared
.
Offsets both the Start and End locations in screen coordinates. This may be helpful when using data from the Tracker.
-
Negate Shift:
Check-box, Default:
off,
Shared
.
If enabled, the Screen Shift is subtracted from the Start and End locations instead of added. It is also meant to help when using data from the Tracker.
-
Brightness:
Default:
1,
Range:
0 or greater,
Shared
.
Scales the brightness of the gradient image (both the Start Color and End Color).
-
Start Color:
Default rgb:
[1 1 1],
Shared
.
The color of the gradient at the Start location.
-
End Color:
Default rgb:
[0 0 0],
Shared
.
The color of the gradient at the End location
-
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.
