In the Sapphire Lighting category.


Inputs:

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.

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.

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.
