Describe motion with easing curves, not adjectives

The prompt

Instead of "make it bounce naturally," specify the easing curve directly: "ease-out-elastic over 400ms." Most motion-graphics tools and AI video models respond far more predictably to named easing curves than to descriptive adjectives.

Expected result

Motion that matches a specific, repeatable easing profile instead of an inconsistent interpretation of "natural" or "bouncy."

Why it works

Easing curve names are a shared vocabulary between animators and motion tools — using them removes ambiguity that adjectives leave open.
