Lottie Animation Principles
Implement all 12 Disney animation principles using Lottie (Bodymovin) for vector animations.
1. Squash and Stretch
In After Effects before export:
- Animate Scale X and Y inversely
- Use expression:
s = transform.scale[1]; [100 + (100-s), s]
// Control at runtime
lottie.setSpeed(1.5); // affect squash timing
2. Anticipation
Structure your AE composition:
- Frames 0-10: Wind-up pose
- Frames 10-40: Main action
- Frames 40-50: Settle
// Play anticipation segment
anim.playSegments([0, 10], true);
setTimeout(() => anim.playSegments([10, 50], true), 200);
3. Staging
// Layer multiple Lotties
<div className="scene">
<Lottie animationData={background} style={{ opacity: 0.6 }} />
<Lottie animationData={hero} style={{ zIndex: 10 }} />
</div>
4. Straight Ahead / Pose to Pose
Pose to pose in AE:
- Set keyframes at key poses
- Let AE interpolate between
- Use Easy Ease for smoothing
// Jump to specific poses
anim.goToAndStop(25, true); // frame 25
5. Follow Through and Overlapping Action
In After Effects:
- Offset child layer keyframes by 2-4 frames
- Use parenting with delayed expressions
thisComp.layer("Parent").transform.position.valueAtTime(time - 0.05)
6. Slow In and Slow Out
AE Keyframe settings:
- Select keyframes > Easy Ease (F9)
- Use Graph Editor to adjust curves
- Bezier handles control acceleration
// Adjust playback speed dynamically
anim.setSpeed(0.5); // slower
anim.setSpeed(2); // faster
7. Arc
In After Effects:
- Use motion paths (position property)
- Convert keyframes to Bezier
- Pull handles to create arcs
- Or use "Auto-Orient to Path"
8. Secondary Action
// Trigger secondary animation
mainAnim.addEventListener('complete', () => {
secondaryAnim.play();
});
// Or sync with frame
mainAnim.addEventListener('enterFrame', (e) => {
if (e.currentTime > 15) particleAnim.play();
});
9. Timing
anim.setSpeed(0.5); // half speed - dramatic
anim.setSpeed(1); // normal
anim.setSpeed(2); // double speed - snappy
// Or control frame rate in AE export
// 24fps = cinematic, 30fps = smooth, 60fps = fluid
10. Exaggeration
In After Effects:
- Push scale beyond 100% (120-150%)
- Overshoot rotation
- Use Overshoot expression
amp = 15; freq = 3; decay = 5; n = 0; time_start = key(1).time; if (time > time_start) { n = (time - time_start) / thisComp.frameDuration; amp * Math.sin(freq*n) / Math.exp(decay*n/100); } else { 0; }
11. Solid Drawing
In After Effects:
- Use 3D layers
- Apply perspective camera
- Animate Z position and rotation
- Use depth of field
12. Appeal
Design principles in AE:
- Smooth curves over sharp angles
- Consistent timing patterns
- Pleasing color palette
- Clean vector shapes
// React Lottie with hover
<Lottie
animationData={data}
onMouseEnter={() => anim.setDirection(1)}
onMouseLeave={() => anim.setDirection(-1)}
/>
Lottie Implementation
import Lottie from 'lottie-react';
import animationData from './animation.json';
<Lottie
animationData={animationData}
loop={true}
autoplay={true}
style={{ width: 200, height: 200 }}
/>
