Outline a clip in glowing neon. Every strong edge becomes a bright tube of light, and the picture behind it sinks into darkness, the look of Tron-style title sequences and music visuals.
Color and glow
Neon Color sets the tube and glow color. Glow Radius sets how far the light spreads from each line, and Intensity how bright the halo is. A cyan or magenta on a nearly black background gives the classic look.
Background dim
Background Dim darkens and tints the original frame. At 100% only the outlines remain; around 70% the scene stays faintly visible under the neon.
Footage that works
Subjects with clear silhouettes against simple backgrounds give clean outlines: dancers on a plain wall, cars against sky, product shots. Busy textures such as foliage turn into dense scribbles of light.
