S_Sparkles Generates a field of sparkling glint effects. Adjust the Frequency, Density, and Size parameters for different types of sparkling patterns. Use the Matte input to only generate sparkles in specified areas. In the Sapphire Render effects submenu. Inputs: Background:  Optional.   The clip to combine the sparkles with. Mask:  Optional.   If provided, the sparkle colors are scaled by this input. A monochrome mask can be used to choose the areas that will generate sparkles. A color mask can be used to selectively adjust the sparkle colors in different regions. The mask is applied before the sparkles are generated so it will not clip the resulting glint rays.

Parameters:

Frequency:   Default: 25,  Range: 0.01 or greater.
The frequency of the sparkles. Increase to zoom out, decrease to zoom in.

Density:   Default: 0.65,  Range: 0 to 1.
Increase to add more sparkles.

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.

Brightness:   Default: 1,  Range: 0 or greater.
Scales the brightness of all the sparkles.

Color:   Default rgb: [1 1 1].
Scales the color of all the sparkles.

Brightness X:   Default: 1,  Range: 0 or greater.
Scales the brightness of the horizontal glint rays.

Brightness Y:   Default: 1,  Range: 0 or greater.
Scales the brightness of the vertical glint rays.

Brightness Diag1:   Default: 1,  Range: 0 or greater.
Scales the brightness of the diagonal rays from top right to bottom left.

Brightness Diag2:   Default: 1,  Range: 0 or greater.
Scales the brightness of the diagonal rays from top left to bottom right.

Size:   Default: 0.25,  Range: 0 or greater.
Scales the length of all the glint rays. This and all the size parameters can be adjusted using the Size Widget.

Size X:   Default: 1,  Range: 0 or greater.
Scales the length of the horizontal glint rays.

Size Y:   Default: 1,  Range: 0 or greater.
Scales the length of the vertical glint rays.

Size Diag1:   Default: 0.5,  Range: 0 or greater.
Scales the length of the diagonal rays from top right to bottom left.

Size Diag2:   Default: 0.5,  Range: 0 or greater.
Scales the length of the diagonal rays from top left to bottom right.

Size Red:   Default: 0.6,  Range: 0 or greater.
Scales the length of the red component of the rays. If the red, green, and blue sizes are equal the sparkles will be monochrome.

Size Green:   Default: 0.8,  Range: 0 or greater.
Scales the length of the green component of the rays.

Size Blue:   Default: 1,  Range: 0 or greater.
Scales the length of the blue component of the rays.

Shift Start:   X & Y,   Default: [0 0],  Range: any.
Translation offset of the result.

Shift Speed:   X & Y,   Default: [0 0],  Range: any.
Translation speed of the result. If non-zero, the result is automatically animated to shift at this rate. The result of animated Speed values may not be intuitive, so for variable speed motion it is usually best to set this to 0 and animate the Shift Start values instead.

Sparkle Speed:   X & Y,   Default: [0.1 0],  Range: any.
If non-zero, the sparkles automatically twinkle on and off at this rate.

Affect Alpha:   Default: 0,  Range: 0 or greater.
If this value is positive the output Alpha channel will include some opacity from the sparkles. The maximum of the red, green, and blue sparkle brightness is scaled by this value and combined with the background Alpha at each pixel.

Bg Brightness:   Default: 1,  Range: 0 or greater.
Scales the brightness of the background before combining with the Sparkles. If 0, the result will contain only the sparkles image over black.

Smooth Anim:   Check-box,  Default: off.
Enable for more steady animation, especially at high values of Frequency.

Invert Mask:   Check-box,  Default: off.
If on, inverts the mask input so the effect is applied to areas where the Mask is black instead of white. This has no effect unless the Mask input is provided.

Show Size: Check-box, Default: on.
Turns on or off the screen user interface for adjusting the size parameters.

Show Shift Start: Check-box, Default: on.
Turns on or off the screen user interface for adjusting the Shift Start parameter.
