GlowOrthicon In the S_Glows Plugin. The source clip is darkened at areas around parts of the source clip that are brighter than the given threshold, to give an 'orthicon' or 'dark glow' look. Lower the Threshold parameter to produce the orthicon effect in more areas. Adjust the Darkness and Width parameters to give different types of looks. Inputs: Source:  The input clip that determines the locations to be darkened.

Parameters:

Darks Width:   Default: 0.2,  Range: 0 or greater.
Scales the dark glow distance. This and all the width parameters can be adjusted using the Width Widget.

Protect Width:   Default: 0.1,  Range: 0 or greater.
The distance around the bright areas that is protected from darkening. This should normally be less than the value of Darks Width.

Protect Amount:   Default: 1,  Range: 0 or greater.
The amount that the bright areas are protected from darkening.

Width X:   Default: 1,  Range: 0 or greater.
Scales the horizontal glow width. Set to 0 for vertical only.

Width Y:   Default: 1,  Range: 0 or greater.
Scales the vertical glow width. Set to 0 for horizontal only.

Subpixel:   Check-box,  Default: off.
Enables glowing by subpixel widths. Use this for smoother animation of the Width parameters.

Darkness:   Default: 1,  Range: 0 or greater.
Scales the amount of darkening.

Color:   Default rgb: [0 0 0].
Scales the color of the glows. The colors and brightnesses of the glows are also affected by the Source input.

Threshold Add Color:   Default rgb: [0 0 0].
This can be used to raise the threshold on a specific color and thereby reduce the glows generated on areas of the source clip containing that color.

Threshold:   Default: 0.7,  Range: 0 or greater.
Darkening will occur around locations in the source clip that are brighter than this value. A value of 0.9 causes dark glows from only the brightest spots. A value of 0 causes glows for every non-black area.

Scale Source:   Default: 1,  Range: 0 to 1,  Shared.
Scales the brightness of the Source input when combined with the glows. This does not affect the generation of the glows themselves.

Params2:

Show:   Popup menu,  Default: Result.
Selects the type of output

Result:  Shows the final result of combining the glow, source, and background.

Threshold:  Shows the thresholded image that is used to generate the glow.
