Echo

Fast-moving objects are smeared along their path as if shot with a longer exposure, which makes quick motion look smooth; unlike Echo it is a continuous streak, not separate copies.

This is for a motion graphics video. Add "Motion Blur" (also called motion smear) to the fast moves in [scene]: whatever moves quickly should streak along its own path, as if the shutter stayed open while it travelled.
Blur only the things that are moving, in the direction they move, as one continuous streak that grows with speed — not separate trailing copies, which is an echo, and not the whole frame, which is a whip pan. Anything holding still stays sharp.
Keep it on for [duration], with a wide shutter angle for long soft streaks or a narrow one for short crisp ones.

Light or imagery is stretched into long, flowing streaks as the picture is exposed through a moving slit, giving a psychedelic tunnel of color.

This is for a motion graphics video. Give [scene] a "Slit-Scan" look (also called the star gate effect): the picture is exposed through a narrow slit that travels across the frame, so each strip of the image comes from a different moment.
Whatever moves should stretch into long, flowing streaks that bend along its path, while whatever holds still stays sharp — separate ghost copies would be an echo, and an even smear along the direction of travel is motion blur.
Let the streaks build and resolve over [duration], and move the slit at a steady pace so the stretch stays continuous.

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.

Moving footage suddenly stops on a single frame that is held like a photograph; differs from Bullet Time because nothing continues to move.

This is for a motion graphics video. Stop the action in [scene] with a "Freeze Frame" (also called a stop-frame or hold frame): the moving footage halts on a single frame and holds like a photograph.
Nothing at all should move during the hold, neither the subject nor the camera — if the viewpoint keeps travelling around the frozen moment, that is bullet time.
The whole beat lasts [duration]; cut into the hold abruptly, mid-action, and leave it long enough to read.

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.
