Melt a clip into cascading streaks of sorted color, the signature look of glitch art. Pixels in the brighter (or more colorful) parts of the frame are pulled out of place and reordered into gradients.
Threshold
Threshold decides which pixels are allowed to melt. At 200 only highlights streak; at 50 almost the whole frame does. Finding the value where the subject stays intact and the sky or background melts is most of the work.
Direction and sort key
Vertical sorting gives waterfalls, horizontal sorting gives smears. Luminance sorts dark to light, Hue sorts through the color wheel for rainbow streaks, and Saturation orders from gray to vivid.
Pixel sorting in motion
On video, runs shift every frame as light and motion change, so streaks shimmer and crawl. Locked-off shots with a moving subject against a bright background give the most readable result.
