Glow In the S_Glows Plugin. Areas of the source clip that are brighter than the given threshold are glowed and then combined with the source clip. Inputs: Source: The input clip that determines the glow locations and colors. This clip is also used as the background and the glows are layered back onto it.

Parameters:

Load Preset: Push-button .
Brings up the Preset Browser to browse all available presets for this effect.

Save Preset: Push-button .
Brings up the Preset Save dialog to save a preset for this effect.

Width: Default: 0.3, Range: 0 or greater.
Scales the glow distance. This and all the width parameters can be adjusted using the Width Widget. Note that a zero glow width still enhances the bright areas; set the brightness parameter to zero if you want to pass the Source through unchanged.

Width Red: Default: 1, Range: 0 or greater.
Scales the red glow width. If the red, green, and blue widths are equal, the glows will match the color of the source clip. If they are not equal, the glows will vary in color with distance.

Width Green: Default: 1.2, Range: 0 or greater.
Scales the green glow width.

Width Blue: Default: 1.4, Range: 0 or greater.
Scales the blue glow width.

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

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.

Brightness: Default: 2, Range: 0 or greater.
Scales the brightness of all the glows.

Color: Default rgb: [1 1 1].
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: 0.5, Range: 0 or greater.
Glows are generated from locations in the source clip that are brighter than this value. A value of 0.9 causes glows at 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.

Eclipse With Bg: Default: 0, Range: 0 to 1, Shared .
If this is set to 1, the background is subtracted from the glow and gives an eclipsed shadow effect.

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.

Combine: Popup menu,  Default: Screen .
Determines how the glow is combined with the Source or Background. This parameter has no effect if Light BG is set to 1.

Mult: the source or background is multiplied by the glow.

Add: the glow is added to the source or background.

Screen: the glow is blended with the source or background using a screen operation.

Difference: the result is the difference between the glow and the source or background.

Overlay: the glow is combined with the source or background using an overlay function.

Edge Mode: Popup menu,  Default: Reflect .
Determines the behavior when accessing areas outside the source image.

Black: Areas outside the source image are treated as black, which can produce dark areas around the edges of the image. Select this for fastest rendering.

Reflect: Reflects the image outside the border.

Atmosphere Parameters:

Atmosphere Amp: Default: 0, Range: 0 or greater.
Atmosphere gives the effect of the glow shining through a dusty atmosphere and picking up light or getting shadowed. This parameter adjusts the amount, or amplitude, of the atmospheric effect. Zero gives a smooth glow, higher values give more dusty look.

Atmosphere Freq: Default: 1, Range: 0.1 or greater.
Controls the spatial frequency of the atmospheric noise. Turn this up higher to get finer details, turn down for broader overall variation.

Atmosphere Detail: Default: 0.6, Range: 0 to 1.
Controls the amount of fine detail in the atmosphere simulation. Decrease to get smoother atmosphere, increase for a more crunchy or grainy look.

Atmosphere Seed: Default: 0.123, Range: 0 or greater.
Used to initialize the random number generator for the atmospheric noise. The actual seed value is not significant, but different seeds give different results and the same value should give a repeatable result.

Atmosphere Speed: Default: 1, Range: any.
The cloudy noise in the atmosphere evolves over time like real dust clouds; this parameter controls how fast the cloud pattern changes over time. Set to zero for a static pattern.

Params3:

Mocha: Default: 0, Range: 0 or greater, Shared .
Brings up the Mocha window for tracking footage and generating masks.

Blur Mocha: Default: 0, Range: 0 or greater, Shared .
Blurs the Mocha Mask by this amount before using. This can be used to soften the edges or quantization artifacts of the mask, and smooth out the time displacements.

Mocha Opacity: Default: 1, Range: 0 to 1, Shared .
Controls the strength of the Mocha mask. Lower values reduce the intensity of the effect.

Invert Mocha: Check-box,  Default: off, Shared .
If enabled, the black and white of the Mocha Mask are inverted before applying the effect.

Show Mocha Only: Check-box,  Default: off, Shared .
Bypass the effect and show the Mocha Mask itself.

Bypass Mocha: Check-box,  Default: off, Shared .
Ignore the Mocha Mask and apply the effect to the entire source clip.
