S_EdgeFlashAdds 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.

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

Check-box, ย Default:
off.
Bypass the effect and show the Mocha Mask itself.
-
Combine Masks:
Popup menu, ย 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.
- Intersect: Uses the area that overlaps between the two masks.
-
Union:
Uses the area covered by both masks together.
-

-
Foreground:
outputs only the Front clip with flashing from the Back.
-
Subpixel Widths:
Check-box, ย Default:
off.
Enables flashing by subpixel amounts. Use this for smoother animation of the flash width.
-
Comp Premult:
Check-box, ย 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.
-

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.

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.

Popup menu, ย 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.
- Alpha: only the Alpha channel is used, or if there is no valid Alpha channel the Red channel is used.
-
Luma:
the luminance of the RGB channels is used.
-
Invert Matte:
Check-box, ย Default:
off.
If enabled, the black and white of the output matte are inverted.
