Sapphire Plug-ins for AVX2: DropShadow


Generates a shadow on the Background clip using the alpha channel of the Foreground or an optional Matte, then composites the Foreground over the Background to give the final result.

In the Sapphire Lighting category.


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

Background: Optional. The shadow is drawn onto this Background clip.

Matte: Optional. If this is provided, its alpha channel is used instead of the Foreground to generate the shadow. This input can be affected by the Invert Matte or Matte Use parameters.

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.

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.

The horizontal and vertical offset of the shadow.

The color of the shadow.

Shadow Opacity: Default: 1, Range: 0 or greater.
The opacity of the shadow, use values near 0 for subtle transparent shadows, or values near 1.0 for stronger shadows.

Blur Shadow: Default: 0.1, Range: 0 or greater.

Fg Opacity: Default: 1, Range: 0 to 1.

Matte Use: Popup menu,  Default: Alpha .
Determines which Foreground or Matte input channels are used to make the shadow.
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 Foreground alpha channel are inverted before use.

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