EdgeFlash Adds a glow from the Front clip onto the Back clip, and vice versa, then composites the Front over the Back. This can be used to make a composite look more natural with light flashing between the layers as if exposed on film together. Inputs: Front:  The clip to use as foreground. Back:  The clip to use as background. Matte:  Specifies the opacities of the Front clip. Only the red channel of this input is used.

Parameters:

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

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

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.

FRONT:  outputs only the Front clip with flashing from the Back.

BACK:  outputs only the Back clip with flashing from the Front.

COMP:  flashes both, composites the Front over the Back, and outputs the result.

Comp Premult:   Check-box,  Default: off.
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.

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

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

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.
