Pixelate

Video compression is exploited (I-frames removed) so the next clip's motion drags and melts the pixels of the one before it, producing smeared, bleeding blocks.

This is for a motion graphics video. At the cut between the two shots in [scene], use a "Datamosh" (also called datamoshing): instead of switching cleanly, let the old picture stay on screen and be pushed around by the motion of the new shot, as if the compressed video had lost its keyframe.
The leftover image should smear and bleed in blocks along the direction things move, melting away piece by piece until the new shot is fully there — a slow melt at a cut, unlike a glitch, which tears for an instant and snaps back.
Let the melt play out over [duration], then leave the new shot clean.

Footage plays backwards so broken things reassemble and movements undo themselves.

This is for a motion graphics video. Play [scene] in "Reverse Motion" (also called reverse or reverse action): the footage runs backwards.
Every movement should undo itself along exactly the path it took — what fell rises again, what scattered comes back together — at the pace it originally happened.
Fit it into [duration], and add no easing of your own so it reads as time rewinding rather than a new move.

The red, green and blue channels are offset so colored fringes appear on edges, often pulsing or snapping on hits; borrowed from a lens defect and used as a style.

This is for a motion graphics video. Add an "RGB Split" (also called chromatic aberration, color fringing or a channel split) to [scene]: slide the colour channels apart sideways so every edge picks up a coloured fringe on each side.
That is the whole effect — the picture itself stays intact and in place. Nothing tears, jumps or breaks into blocks, which would make it a full glitch.
Over [duration], snap the channels apart on each hit and let them drift back together, ending perfectly aligned.

A ring or dome races outward from an impact point, often distorting the picture behind it as it passes.

This is for a motion graphics video. Add a "Shockwave" (also called a shock wave) to the impact in [scene]: a ring races outward from the point of the hit.
As it passes it should bend and push the picture behind it, then thin out and fade — a ring that only decorates an element and leaves the picture untouched is a circle burst.
Fire it on the exact frame of the impact and let it cross the frame within [duration], fast at first and slowing as it spreads.
