Deliberate Animations (1200-2000ms)

At 1200-2000ms, you're creating experiences, not interfaces. This duration is for moments of genuine storytelling where animation itself is the content.

Disney Principles at Deliberate Speed

Full Narrative Expression

Squash & Stretch: Character-defining - 30-40% deformation creates personality. Objects become characters.

Anticipation: Full dramatic preparation - 300-400ms wind-up creates tension and expectation.

Staging: Scene direction - think cinematography. Establish shot, then detail. Clear narrative flow.

Straight Ahead/Pose to Pose: Pose to pose mandatory - 6-10 key poses define the narrative arc.

Follow Through: Extended settling - 300-500ms of secondary motion after primary completes.

Slow In/Slow Out: Narrative pacing - ease curves tell emotional stories. Sharp starts mean urgency, soft ends mean resolution.

Arcs: Orchestrated paths - motion paths are designed, not default. Each element's trajectory contributes to composition.

Secondary Action: Full ecosystem - primary, secondary, tertiary, ambient all working together.

Timing: 72-120 frames at 60fps. Animation-quality frame counts.

Exaggeration: Emotional amplification - push for feeling, not just movement.

Solid Drawing: Dimensional storytelling - parallax, depth, perspective shifts create space.

Appeal: Deep emotional engagement - users feel something during these animations.

Easing Recommendations

/* Narrative arc - beginning, middle, end */
animation-timing-function: cubic-bezier(0.34, 0, 0.14, 1);

/* Graceful, considered motion */
transition: all 1500ms cubic-bezier(0.16, 1, 0.3, 1);

/* Building momentum */
transition: all 1800ms cubic-bezier(0.65, 0, 0.35, 1);

/* Elastic storytelling */
transition: transform 1600ms cubic-bezier(0.68, -0.6, 0.32, 1.6);

Best Use Cases

Story-driven onboarding
Feature announcements

Implementation Pattern

@keyframes appLaunch {
  0% {
    opacity: 0;
    transform: scale(0.6) translateY(50px);
    filter: blur(10px);
  }
  30% {
    opacity: 1;
    filter: blur(5px);
  }
  60% {
    transform: scale(1.02) translateY(-10px);
    filter: blur(0);
  }
  80% {
    transform: scale(0.99) translateY(5px);
  }
  100% {
    transform: scale(1) translateY(0);
  }
}

.app-launch {
  animation: appLaunch 1800ms cubic-bezier(0.16, 1, 0.3, 1) forwards;
}

Critical Considerations

Users MUST be able to skip/dismiss
Never block critical paths
Avoid on repeat visits (detect returning users)
Must add genuine value, not decoration
Test for motion sensitivity (prefer reduced motion)

Key Insight

Deliberate animations are brand investments. They don't just show what's happening - they make users feel something. Budget for design, iteration, and testing. These moments define perceived quality.
