Lifelike motion

Anyone can place a keyframe. Good animation follows rules — a beat of anticipation before the move, weight that overshoots and settles, a secondary part that drags behind. Prism gives your AI those rules, so what it builds feels designed, not robotic. This is the part of Prism that makes AI motion actually look like motion design.

The laws of animation, applied by intent

The Disney principles are the difference between a layer that moves and a layer that feels alive. Prism knows them, and applies the ones that translate to motion graphics — on request, or as the finishing pass on a move it just built.

• Anticipation — a small wind-up before the action, so the eye is ready for it
• Follow-through and overlapping action — parts that keep moving and settle after the main mass stops
• Squash and stretch — weight and elasticity, without distorting the artwork
• Secondary action — a supporting motion that reinforces the main one
• Staging — emphasis that leads the eye to what matters in the frame
• Arcs — natural curved paths instead of stiff straight lines
• Slow in and slow out — the eases that make starts and stops feel real

Reproducing these by intent — "give the logo a little anticipation, then let the badge follow through" — is the hardest part of animation to get right. Prism knows the vocabulary, so you can ask for it by name.

Real spring physics

Ask for a spring and you get a real one. Prism simulates stiffness, damping, and mass, then bakes the result down to clean keyframes — so you get true springy settle and multi-bounce overshoot without an expression slowing your comp, and you can still hand-tune the curve afterward.

• "Settle softly" or "spring stiff" — by feel, not by number
• Bounce and elastic motion that normally needs an expression or a paid plugin
• Baked to keyframes, so the timeline stays light and editable

A vocabulary of feel

Designers describe motion by feel — snappy, gentle, iOS default. Prism speaks that language. It carries 50+ named easing curves, matched to the references designers already trust, and applies any of them to the keyframes you choose.

• Every classic ease — sine, cubic, quart, expo, circ, back
• Springy families — bounce, elastic, spring
• Web standards — Material, iOS, and CSS defaults

Web-motion, translated

If you think in web motion — a fade-up, a slide-in, a pop, a staggered list — just say it. Prism translates that shorthand into native After Effects keyframes, including staggering one move across many layers from any origin (first, last, center, or edges).

Whatever you ask for lands as real keyframes you can still edit, not a baked script.
