Datamosh

The picture briefly breaks like a digital or analog error, with distortions, pixelation and abrupt shifts; the broad umbrella that includes RGB Split and Datamosh.

This is for a motion graphics video. Hit [scene] with a "Glitch Effect" (also called a digital glitch, glitch art or a glitch transition): for a moment the picture breaks like a signal error, then snaps back as if nothing happened.
Tear it into horizontal bands that jump sideways, split the colours on the torn parts, drop in a few stray blocks and jolt the whole frame — changing abruptly from frame to frame, never smoothly. It comes in short bursts; a constant worn texture would be a VHS look instead.
Keep each burst brief within [duration], and avoid flashing the whole frame bright and dark.

The image is broken into large visible squares; animating the block size makes it resolve into or dissolve out of coarse pixels. Static pixelation alone is the censor-mosaic look.

This is for a motion graphics video. "Pixelate" [scene] (also called a mosaic or pixelation): break the picture into a grid of large flat squares, each filled with the single colour of what lies under it.
Animate the block size in clear steps — let the sharp picture dissolve into coarse blocks, hold there while the footage keeps playing underneath, then resolve back to sharp. Held at one block size with no change, it is only a censor mosaic.
Run the whole effect over [duration], and keep the squares aligned to one fixed grid so they do not swim.

The picture wavers as if seen through hot air or water because pixels are pushed around by a moving noise map.

This is for a motion graphics video. Add a "Displacement Distortion" (also called heat haze, heat shimmer or turbulent displacement) to [scene]: make the picture waver as if seen through hot air, by pushing its pixels around with a noise map that keeps drifting.
Everything stays where it is and only bends and wobbles softly in place; the shot does not change, which is what separates it from a ripple dissolve.
Keep it shimmering for [duration], with the noise rising slowly so the wobble never repeats or freezes.

Copies of earlier frames are blended behind the current one so a moving subject leaves a fading trail of itself; differs from Motion Blur in that the copies stay distinct instead of smearing continuously.

This is for a motion graphics video. Add an "Echo" (also called ghosting, trails or motion trails) to the moving subject in [scene]: copies of its earlier frames linger behind it and fade away.
Each copy should stay a separate, readable ghost stepping back along the path, fainter the older it is — a continuous smear would be motion blur.
Run it over [duration], and let the trail catch up and vanish once the subject comes to rest.

Footage plays back at a constant speed faster than real time so movement looks hurried or comic; unlike Time-Lapse it is just sped-up continuous footage, not frames sampled at long intervals.

This is for a motion graphics video. Play [scene] in "Fast Motion" (also called undercranking).
Run the continuous footage at one constant speed, faster than real time, so the action looks hurried and a little comic but still flows smoothly — a time-lapse would skip long gaps between frames instead.
Fit the whole action into [duration] without changing speed along the way.
