# Motion Design

**For Video Content Creation**

Motion serves communication, not decoration. Every animation must guide attention and express intent.

## The 4 Core Concepts

All motion design derives from these four ideas:

### [1. Intent → Strategy](references/1-intent.md)
Message + Emotion → Motion characteristics

What should the viewer feel? This determines material selection and personality.

### [2. Physics Model](references/2-physics-model.md)
Material + Weight + Force → Timing + Deformation + Easing

Material properties determine how objects move. Contains reference tables for durations, deformation, bounce, and easing curves.

### [3. Attention Flow](references/3-attention.md)
One focus at a time. Sequence everything.

Plan viewer focus flow. Contains stagger patterns, timing, and sequencing strategies.

### [4. Systematic Iteration](references/4-process.md)
Broad strokes → Easing → Secondary → Polish

Don't perfect details before structure is right. Process for iterating from concept to polish.

## Decision Framework

```
START: What's the message?
  ↓
INTENT: What should viewer feel?
  → Determines material personality
  ↓
PHYSICS MODEL: What material expresses that?
  → Material determines timing/deformation/bounce
  → Weight scales duration
  → Force determines easing
  ↓
ATTENTION: What's the viewing sequence?
  → Determines stagger patterns
  → Ensures one focus at a time
  ↓
PROCESS: Iterate systematically
  → Broad strokes → Easing → Secondary → Polish
```

## Core Rules

1. **One focus at a time** - Never animate unrelated elements simultaneously
2. **Intent first** - Every animation serves the message
3. **Material consistency** - All elements of same material move similarly
4. **Exits faster than entrances** - 30-40% shorter duration
5. **Respect physics** - Unless intentionally stylized

## Video-Specific Considerations

- Work in **frames**, not just milliseconds (24fps, 30fps, 60fps)
- Consider **composition duration** and pacing for full se
