GlowDarksIn the S_Glows Plugin.Areas of the source clip darker than the given threshold are blurred and combined with the input clip to give a deep smoky look. Adjust the Darkness, Width, and Threshold parameters to give different types of looks. Inputs:

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:
1,
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 affects the dark areas; set the darkness parameter to zero if you want to pass the Source through unchanged.
-
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.
The magnitude of the dark glows.
-
Threshold:
Default:
0.5,
Range:
0 or greater.
Dark glows will be generated from locations in the source clip that are darker than this value. A value of 0.1 causes glows at only the darkest areas. A value of 1.0 causes glows on every non-white area.
-
Glow Saturation:
Default:
1,
Range:
0 or greater.
Scales the saturation of the dark colors. Increase for more intense colors.
-
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.
- Threshold: Shows the thresholded image that is used to generate the glow.
-
Result:
Shows the final result of combining the glow, source, and background.
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.
