Follow Through and Overlapping Action

A smaller supporting motion plays alongside the main one to add life without stealing focus.

This is for a motion graphics video. Add a "Secondary Action" to the main motion in [scene]: a smaller supporting movement that plays alongside it — a small accent, a blink, a flick — to give it more life.
It is a little gesture of its own, not a loose part dragged along behind the body (that is follow through), and it must never pull attention away from the main action.
Fit both into [duration], and let the small movement begin and end inside the main one.

Outlines tremble slightly frame to frame as if redrawn each time, giving a lively handmade look even when the shape stays still.

This is for a motion graphics video. Give the outlines in [scene] a "Line Boil" (also called boiling lines or wiggly lines): redraw every line slightly differently every few frames, so it trembles in place even while the shape itself stays still.
It should change in small sudden steps at a low frame rate, like flipping through hand-traced drawings — not flow smoothly, which reads as liquid, and not shift the whole shape around, which is a wiggle.
Keep it boiling for [duration], and keep the tremble small enough that the shape stays easy to read.

The object passes its target slightly and then returns to it; differs from Bounce in that it makes one pass and settles without hitting a floor.

This is for a motion graphics video. End the move in [scene] with an "Overshoot" (also called a back ease or back out): the object runs slightly past its target, then comes back and settles on it.
It should pass the target only once, with no wobble afterwards — a bounce hits the target and rebounds without passing it, and an elastic ease swings past it several times.
Fit the move into [duration], and keep the overshoot small so it reads as energy rather than a mistake.

The motion plays forward then in reverse repeatedly; differs from Cycle Loop by not jumping back to the start.

This is for a motion graphics video. Repeat the motion in [scene] as a "Ping-Pong Loop" (also called a yoyo or boomerang): it plays forward to the end, then plays in reverse back to the start, and keeps going back and forth.
It should never jump — a cycle loop snaps back to the first frame and restarts, while this one retraces its own path.
Keep it going for [duration], with a soft turn at each end so the change of direction feels like breathing rather than hitting a wall.
