Optics-2022 : Filters : S_Glint
S_Glint
Description
Generates star shaped glints at locations where the image is brighter than the threshold.
The S_Glint filter comes from the Emmy award winning Boris FX Sapphire filter set.

Brightness
Scales the brightness of all the glints.
Brightness Details
Scale Colors
Scales the color of the glints.
Brightness X
Scales the brightness of the horizontal glint rays.
Brightness Y
Scales the brightness of the vertical glint rays.
Brightness Diag1
Scales the brightness of the diagonal rays from top right to bottom left.
Brightness Diag2
Scales the brightness of the diagonal rays from top left to bottom right.
Threshold
Glints are generated from locations in the image that are brighter than this value. A value of .9 causes glints at only the brightest spots. A value of 0 causes glints for every nonāˆ’black area.
Threshold Add Color
This can be used to raise the threshold on a specific color and thereby reduce the glints generated on areas of the image containing that color.
Threshold Blur
Increase to smooth out the areas creating glints. This can be used to eliminate glints generated from small speckles or to simply soften the glints. Increasing this may put more highlights below the threshold and darken the resulting glints, but you can decrease the Threshold parameter to compensate.
Size
Scales the length of all glint rays. Note that a 0 glint size still enhances the bright areas. Set the brightness parameter to 0 if you want to pass the image through unchanged.
Size Details
Size X
Scales the length of the horizontal glint rays.
Size Y
Scales the length of the vertical glint rays.
Size Diag1
Scales the length of the diagonal rays from top right to bottom left.
Size Diag2
Scales the length of the diagonal rays from top left to bottom right.
Size Red
Scales the length of the red component of the rays. If the red, green, and blue sizes are equal, the glints will be uniform in color and will match the color of the image. If they are not equal, the glint colors can vary along the lengths of the rays.
Size Green
Scales the length of the green component of the rays.
Size Blue
Scales the length of the blue component of the rays.
Blur Glint
The glints are blurred by this amount before being combined with the background.
Hue Shift
Shifts the hue of the glint, in revolutions from red to green to blue to red.
Glint From Alpha
The glint is generated from the alpha channel instead of the RGB channels. In this case, the glint will not use color from the image and will typically be brighter. Values between 0 and 100 interpolate between using the RGB and the alpha.
Glint Under Source
Set to 1 to composite the image over the glints.
Source Opacity
Scales the opacity of the image when combined with the glints. This does not affect the generation of the glints themselves.
Expand Borders
If enabled, transparent borders are added to the image before processing. This allows the result to include soft edges beyond the original image size. When off, the effect only occurs within the frame and the result will retain an edge at the borders.
Show Size
Enables/disables the on-screen control for adjusting the size parameters.
