## Style Presets
Apply these when user specifies a style:
### Minimalist (default)
```tsx
const COLORS = {
primary: '#18181B',
secondary: '#71717A',
accent: '#3B82F6',
background: '#FAFAFA',
text: '#18181B',
};
// Characteristics: Maximum whitespace, subtle animations, thin fonts, no decorative elements
```
### Memphis
```tsx
const COLORS = {
primary: '#FF6B6B',
secondary: '#4ECDC4',
accent: '#FFE66D',
background: '#F7FFF7',
text: '#2D3436',
};
// Characteristics: Geometric shapes (triangles, circles, squiggles), bold black outlines, scattered elements, confetti particles
```
### Neo-brutalism
```tsx
const COLORS = {
primary: '#FF5C00',
secondary: '#3B82F6',
accent: '#FACC15',
background: '#FFFFFF',
text: '#000000',
};
// Characteristics: Harsh black borders (3-4px), solid color blocks, offset box shadows (4px 4px 0px #000), raw aesthetic
```
### Glassmorphism
```tsx
const COLORS = {
primary: '#FFFFFF',
secondary: '#A855F7',
accent: '#06B6D4',
background: 'linear-gradient(135deg, #667eea 0%, #764ba2 100%)',
text: '#FFFFFF',
};
// Characteristics: Frosted glass (backdrop-filter: blur), transparency, subtle borders, gradient backgrounds
```
### Neon/Cyberpunk
```tsx
const COLORS = {
primary: '#FF00FF',
secondary: '#00FFFF',
accent: '#FFFF00',
background: '#0A0A0F',
text: '#FFFFFF',
};
// Characteristics: Dark backgrounds, glowing effects (box-shadow with color), scanlines, tech-inspired elements
```
### Corporate
```tsx
const COLORS = {
primary: '#1E40AF',
secondary: '#3B82F6',
accent: '#10B981',
background: '#F8FAFC',
text: '#1E293B',
};
// Characteristics: Professional, clean, trustworthy blues, structured layouts, subtle gradients
```
### Green Screen
```tsx
const COLORS = {
primary: '#FFFFFF',
secondary: '#3B82F6',
accent: '#FACC15',
background: '#00FF00',
text: '#000000',
};
// Characteristics: Pure green background (#00FF00) for chroma keying, elements popping/scaling onto the screen, high contrast. NEVER use green tones in elements, shadows, or text to avoid chroma key interference.
```

## Critical Rules
### Interpolate ⚠️
**inputRange MUST be strictly monotonically increasing:**
```tsx
// ✅ Correct
interpolate(frame, [0, 30, 60], [0, 1, 0])
// ❌ Wrong — will throw error
interpolate(frame, [60, 30, 0], [0, 1, 0])
```
**For reverse mapping, flip outputRange, NOT inputRange:**
```tsx
// ✅ Correct — maps 0→100, 1→0
interpolate(value, [0, 1], [100, 0])
// ❌ Wrong
interpolate(value, [1, 0], [100, 0])
```
**Index-based timing — ensure startFrame < endFrame:**
```tsx
// ✅ Correct
const startFrame = index * 30;
const endFrame = startFrame + 30;
interpolate(frame, [startFrame, endFrame], [0, 1], {
extrapolateLeft: 'clamp',
extrapolateRight: 'clamp',
});
```
---
### chroma-js Import ⚠️
```tsx
// ✅ Correct
import * as chroma from 'chroma-js';
const color = chroma('#00bfff').brighten(0.5).hex();
// ❌ Wrong — causes "chroma is not a function" error
import chroma from 'chroma-js';
```
---
### @remotion/paths ⚠️
**These functions DO NOT EXIST — never use them:**
- ❌ makeCircle(), makeRect(), makeTriangle(), makeLine(), makePie(), makePolygon(), makeEllipse(), makeStar()
**Only valid imports:**
```tsx
import { evolvePath, getLength, getPointAtLength, getTangentAtLength } from '@remotion/paths';
```
**Use hand-written SVG path strings:**
```tsx
// ✅ Correct
const circlePath = 'M 50 10 A 40 40 0 1 1 49.99 10 Z';
const rectPath = 'M 0 0 L 100 0 L 100 50 L 0 50 Z';
const linePath = 'M 0 0 L 100 100';
const { strokeDasharray, strokeDashoffset } = evolvePath(progress, rectPath);
```
---
### Easing Functions ⚠️
**NEVER use wrapper syntax:**
```tsx
// ❌ Wrong — will crash
Easing.out(Easing.cubic)
Easing.in(Easing.quad)
```
**ALWAYS use Easing.bezier():**
```tsx
// ✅ Correct
const EASINGS = {
easeOut: Easing.bezier(0.33, 1, 0.68, 1),
easeIn: Easing.bezier(0.32, 0, 0.67, 0),
easeInOut: Easing.bezier(0.37, 0, 0.63, 1),
overshoot: Easing.bezier(0.34, 1.56, 0.64, 1),
};
interpolate(frame, [0, 30], [0, 1], {
easing: EASINGS.easeOut,
extrapolateRight: 'clamp',
});
```
---
### Animation Rules
1. **ALL animations must be frame-based** — use useCurrentFrame() and interpolate()
2. **NEVER use:** useState, useEffect, setTimeout, setInterval, CSS animations
3. **ALWAYS use:** extrapolateLeft: 'clamp' and extrapolateRight: 'clamp'
4. Stagger animations — don't animate everything at once
5. **Composition ID:** PascalCase only, NO hyphens or underscores
---
## Layout Guidelines
### Safe Zones
- **Top 10%:** Reserve for platform UI
- **Bottom 15%:** Reserve for captions/buttons
- **Center content** between 25%–75% vertically
### Centering
```tsx
const centered: React.CSSProperties = {
position: 'absolute',
top: '50%',
left: '50%',
transform: 'translate(-50%, -50%)',
};
```
---
## Typography
| Element | Size | Weight |
|---------|------|--------|
| Headlines | 72–120px | 700–900 |
| Subheadlines | 36–48px | 500–700 |
| Body | 28–36px | 400–500 |
**Always set margin: 0 on text elements.**
