Sapphire Plug-ins for AVX2: Gradient

S_Gradient

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.

In the Sapphire Render category.


Inputs:

Source: The current track. The clip to combine the gradient image with.

Background: Optional. Composites the Source and gradient over this clip.

Mask: Optional. Interpolate between the result and the Source input. White areas use the result of the effect. Black areas use the Source clip.

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.

Mocha: Default: 0, Range: 0 or greater.
Brings up the Mocha window for tracking footage and generating masks.

Blur Mocha: Default: 0, Range: 0 or greater.
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.
Controls the strength of the Mocha mask. Lower values reduce the intensity of the effect.

Invert Mocha: Check-box,  Default: off.
If enabled, the black and white of the Mocha Mask are inverted before applying the effect.

Resize Mocha: Default: 1, Range: 0 to 2.
Scales the Mocha Mask. 1.0 is the original size.

Resize Rel X: Default: 1, Range: 0 to 2.
The relative horizontal size of the Mocha Mask.

Resize Rel Y: Default: 1, Range: 0 to 2.
The relative vertical size of the Mocha Mask.

Shift Mocha: X & Y,   Default: [0 0], Range: any.
Offsets the position of the Mocha Mask.

Bypass Mocha: Check-box,  Default: off.
Ignore the Mocha Mask and apply the effect to the entire source clip.

Show Mocha Only: Check-box,  Default: off.
Bypass the effect and show the Mocha Mask itself.

Combine Masks: Popup menu,  Default: Union .
Determines how to combine the Mocha Mask and Input Mask when both are supplied to the effect.
Union: Uses the area covered by both masks together.
Intersect: Uses the area that overlaps between the two masks.
Mocha Only: Ignore the Input Mask and only use the Mocha Mask.

Start: X & Y,  Default: screen upper center.
The starting location of the gradient. This parameter can be adjusted using the Start Widget.

End: X & Y,  Default: screen lower center.
The ending location of the gradient. This parameter can be adjusted using the End Widget.

Start Color: Default rgb: [1 1 1].
The color of the gradient at the Start location.

End Color: Default rgb: [0 0 0].
The color of the gradient at the End location

Swap Colors: Check-box,  Default: off.
If checked, reverses the direction of the gradient by swapping the Start and End colors.

Brightness: Default: 1, Range: 0 or greater.
Scales the brightness of the gradient image (both the Start Color and End Color).

Add Noise: Default: 0, Range: 0 or greater.
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.

Smooth Curve: Default: 0, Range: 0 to 1.
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.

Scale Background: Default: 1, Range: 0 or greater.
Scales the brightness of the source image before combining it with the gradient.

Combine: Popup menu,  Default: Grad Only .
Determines how the gradient is combined with the source image.
Grad Only: gives the gradient image alone with no source.
Mult: the source is multiplied by the gradient.
Add: the source is added to the gradient.
Screen: the source is blended with the gradient using a screen operation.
Difference: the result is the difference between the source and gradient.
Overlay: combines gradient and source using an overlay function.

Mask Use: Popup menu,  Default: Luma .
Determines how the Mask input channels are used to make a monochrome mask.
Luma: the luminance of the RGB channels is used.
Alpha: only the Alpha channel is used, or if there is no valid Alpha channel the Red channel is used.

Blur Mask: Default: 0.05, Range: 0 or greater.
Blurs the Mask input by this amount before using. This can provide a smoother transition between the masked and unmasked areas. It has no effect unless the Mask input is provided.

Invert Mask: Check-box,  Default: off.
If on, inverts the mask input so the effect is applied to areas where the Mask is black instead of white. This has no effect unless the Mask input is provided.
