Motion Direction

Make the creative decisions for a motion piece before anyone animates a frame. Direction is the judgment layer: it turns a brief and a brand into a small, repeatable set of motion rules — one easing vocabulary, one timing scale, one transition family — so every shot feels like it came from the same hand. Good direction is mostly subtraction: deciding what NOT to move.

When to use

  • Starting any piece — explainer, launch film, UI demo, data story, loop — and the look/feel isn't decided yet.
  • Animation feels "busy", "cheap", or "inconsistent" and the cause is decisions, not craft.
  • Orchestrating other skills (gsap/lottie/shader/three.js): direction sets the rules they execute.
  • Translating a brand or brief into directable, written choices a team (or an agent) can follow.

The one rule

Define the motion language first, then animate to it. A motion language is a short spec — pick one of each: easing family, base timing unit, transition family, stagger rhythm, motion intensity. Everything in the piece obeys it. Consistency reads as confidence; variety reads as noise. When in doubt, reuse, don't invent.

Tone & energy matrix

Place the piece on two axes; the cell dictates the motion language defaults.

Soft (organic, eased)Sharp (precise, snappy)
CalmLuxury, wellness, editorial — slow, long eases, generous holds, minimal staggerPremium tech, fintech — deliberate, clean linear-ish moves, tight but unhurried
KineticPlayful, lifestyle, kids — bouncy/overshoot, springy, loose timingSports, hype, gaming — fast cuts, hard snaps, aggressive overshoot on beats

Pick one cell and commit. Mixing cells within a piece is the most common cause of "inconsistent" motion.

Motion personality (named presets)

The tone matrix tells you where the piece sits; a motion personality is the named, numeric preset you hand to whoever animates. Pick ONE per project and apply it everywhere. This is shared vocabulary — other skills (e.g. gsap-web, micro-interaction, the video packs) can just say "use the Premium personality."

PersonalityDurationSignature easingOvershootReads as
Playful150–300msease-out-back / cubic-bezier(0.34,1.56,0.64,1)10–20%fun, bouncy, whimsical

Default: Corporate for UI/product, Playful for illustration/lifestyle. Maps onto the matrix — Premium≈calm-soft, Corporate≈calm-sharp, Playful≈kinetic-soft, Energetic≈kinetic-sharp. The personality fills the "easing family / base timing unit / motion intensity" rows of the spec below.

The motion-language spec

The core artifact. Fill every row with ONE choice and reuse it everywhere.

PropertyChoose oneExample (calm-sharp / premium tech)
Easing familyThe signature curve for ~90% of movescubic-bezier(0.22, 1, 0.36, 1) (decelerate, soft landing)
Base timing unitThe atomic duration; build others as multiples0.4s (enters 0.4s, big moves 0.8s, micro 0.2s)
Transition familyHow shots connectMatch-cut + crossfade only; no wipes/spins
Stagger rhythmDelay between grouped elements60ms cascade, top-to-bottom
Motion intensityDistance/scale/overshoot budgetTravel ≤ 24px, scale 0.96→1.0, overshoot ≤ 2%
Hold disciplineMinimum rest between moves≥ 0.3s of stillness after each beat

Two eases maximum: one "in" (exits) and one "out" (entrances/landings). A third curve must justify its existence.

Motion hierarchy

Not everything earns motion. Rank every element, then animate down the list — and stop early. These three tiers are the universal three motion layers (see animation-principles): Hero = Primary, Support = Secondary, Texture = Ambient.

TierWhat it isHow it moves
HeroThe one thing the shot is aboutGets the boldest, slowest, most-eased move; lands on the beat
SupportContext that helps the hero landSmaller, faster, eased out of the way; never competes
TextureBackground, grain, ambient driftSubliminal only — slow loops, low contrast, no hard cuts

If two elements compete for the eye in one frame, the direction has failed. Demote one to support.

Restraint — what NOT to animate

The senior move. For each element ask: does the motion carry meaning? If not, hold it still.

  • Don't animate the entire frame at once — stagger or hold a anchor so the eye has a home.
  • Don't transition the transition (no animated wipe and a spin and a fade).
  • Don't loop-animate text the viewer is still reading.
  • Don't add overshoot to serious/financial content — it reads as toy-like.
  • One "wow" moment per piece. A second one cancels the first.

Pacing & rhythm

Pacing is the edit's heartbeat. Vary it on purpose: tension (faster, tighter) → release (a hold). Map energy across the timeline before timing individual moves — most pieces want a low-energy open, a build, a peak, and a settled end card. Cut and land key moments on the audio (see launch-video for beat-syncing); silence and stillness are pacing tools, not gaps to fill.

Consistency check

Before sign-off, audit every shot against the spec table:

  • Same easing family on comparable moves? (No stray linear or ease.)
  • All durations are multiples of the base unit?
  • Only the chosen transition family between shots?
  • Stagger rhythm identical across grouped reveals?
  • Hold discipline respected — no two moves stacked without rest?
  • Exactly one hero per frame?

Any "no" is a direction defect, not a craft preference — fix it before polishing.
