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

Message + Emotion → Motion characteristics

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

2. Physics Model

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

One focus at a time. Sequence everything.

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

4. Systematic Iteration

Broad strokes → Easing → Secondary → Polish

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

Decision Framework

code
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 sequence
  • •Think about viewer distance (mobile vs TV vs cinema)
  • •Plan for audio sync when applicable
  • •Account for export format constraints
