Sapphire Plug-ins for AVX2: EdgeFlash

S_EdgeFlash

Adds a glow from the Foreground clip onto the Background clip, and vice versa, then composites the Foreground over the Background. This can be used to make a composite look more natural with light flashing between the layers as if exposed on film together.

In the Sapphire Composite category.


Inputs:

Foreground: The current track. The clip to use as foreground, and the alpha channel of this clip is used as the matte.

Background: Selectable. The clip to use as background. The output of the effect is composited over this clip.

Matte: Optional. The alpha channel of this input specifies the opacities of the Foreground input. If this input is not provided, the alpha channel of the Foreground input is used instead. This input can be affected by the Invert Matte or Matte Use parameters.

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.

Mode: Popup menu,  Default: Original .
Select which processing method to use
Original: The original method
LightWrap: An improved method that handles some edge conditions better

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.

Fg Flash Amp: Default: 0.8, Range: 0 or greater.
The amount of flashing from the Front onto the Back.

Bg Flash Amp: Default: 0.8, Range: 0 or greater.
The amount of flashing from the Front onto the Back.

Flash Width: Default: 0.1, Range: 0 or greater.
The width of the flashing. This parameter can be adjusted using the Flash Width Widget.

Output: Popup menu,  Default: Comp .
Selects between different output options.
Foreground: outputs only the Front clip with flashing from the Back.
Background: outputs only the Back clip with flashing from the Front.
Comp: flashes both, composites the Front over the Back, and outputs the result.

Subpixel Widths: Check-box,  Default: off.
Enables flashing by subpixel amounts. Use this for smoother animation of the flash width.

Comp Premult: Check-box,  Default: on.
Enable this for a better composite if the Front pixel values have been pre-multiplied by the Matte pixel values. This is also known as an 'additive' composite.

Front Lights: Default: 1, Range: any.
Scales the Front input by this value. Increase for a brighter result

Front Darks: Default: 0, Range: any.
Adds this gray value to the darker regions of the Front input. This can be negative to increase contrast.

Front Sat: Default: 1, Range: 0 or greater.
Scales the color saturation of the Front input. Increase for more intense colors. Set to 0 for monochrome.

Back Lights: Default: 1, Range: any.
Scales the Back input by this value. Increase for a brighter result

Back Darks: Default: 0, Range: any.
Adds this gray value to the darker regions of the Back input. This can be negative to increase contrast.

Back Sat: Default: 1, Range: 0 or greater.
Scales the color saturation of the Back input. Increase for more intense colors. Set to 0 for monochrome.

Matte Use: Popup menu,  Default: Alpha .
Determines how the Matte input channels are used to make a monochrome matte.
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.

Invert Matte: Check-box,  Default: off.
If enabled, the black and white of the output matte are inverted.

Shrink- Grow+: Default: 0, Range: any.
Amount to grow the matte edges in approximate pixels, or shrink if negative.

Edge Softness: Default: 1, Range: 0.01 or greater.
The resulting softness of the edges.

Post Blur: Default: 0, Range: 0 or greater.
If positive, the result is blurred by this amount. This is an alternative method for softening the edges.

Noise Amplitude: Default: 0, Range: 0 or greater.
The amount of noise texture to add to the edges.

Noise Width: Default: 0.05, Range: 0 or greater.
The width of the area at the matte edges where the noise is included. This has no effect unless Noise Amplitude is positive

Frequency: Default: 100, Range: 0.1 or greater.
The frequency of the noise. Increase for finer grain noise, decrease for coarser noise. This has no effect unless Noise Amplitude is positive.

Octaves: Integer,  Default: 1, Range: 1 to 10.
The number of summed layers of noise. Each octave is twice the frequency and half the magnitude of the previous. This has no effect unless Noise Amplitude is positive.

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.

Noise Shift: X & Y,   Default: [0 0], Range: any.
The horizontal and vertical translation of the noise texture.
