## Quick Usage Guide (Step-by-Step)

### Step 1: Scrape Brand Data
```bash
# Run the scrapling script to get brand colors, logo, tagline
bash skills/remotion-video-generator/scripts/scrapling.sh "https://brand-website.com"
```

This extracts: brandName, tagline, logoUrl, faviconUrl, primaryColors, ogImageUrl, screenshotUrl

### Step 2: Download Brand Assets
```bash
mkdir -p public/images/brand
curl -sL "https://brand.com/logo.svg" -o public/images/brand/logo.svg
curl -sL "https://brand.com/og-image.png" -o public/images/brand/og-image.png
curl -sL "https://image.thum.io/get/width/1200/crop/800/https://brand.com" -o screenshot.png
```

### Step 3: Create Project Structure
```bash
mkdir -p my-video/src my-video/public/images/brand my-video/public/audio
```

### Step 4: Create package.json
```json
{
  "name": "my-video",
  "scripts": {
    "dev": "npx remotion studio",
    "build": "npx remotion bundle"
  },
  "dependencies": {
    "@remotion/cli": "^4.0.0",
    "react": "^18.2.0",
    "react-dom": "^18.2.0",
    "remotion": "^4.0.0",
    "lucide-react": "^0.300.0"
  }
}
```

### Step 5: Install Dependencies
```bash
cd my-video && npm install
```

### Step 6: Create Video Component
Create `src/MyVideo.tsx` with:
- AbsoluteFill for full-screen layout
- Sequence components for scene timing
- useCurrentFrame, useVideoConfig, interpolate, spring for animations

### Step 7: Create Entry Point (Remotion v4 API)
Create `src/index.tsx` - **MUST use `.tsx` extension**:

```tsx
import { registerRoot, Composition } from "remotion";
import { AbsoluteFill, Sequence, useCurrentFrame, useVideoConfig, interpolate, spring } from "remotion";

const MyVideo = () => {
  const frame = useCurrentFrame();
  const { fps } = useVideoConfig();

  // Animations - ALWAYS pass fps to spring()
  const scale = spring({ frame, fps, from: 0.8, to: 1 });

  return (
    <AbsoluteFill style={{ backgroundColor: "#000" }}>
      <Sequence from={0} durationInFrames={90}>
        <h1>Hello World</h1>
      </Sequence>
    </AbsoluteFill>
  );
};

registerRoot(() => {
  return (
    <Composition
      id="MyVideo"
      component={MyVideo}
      durationInFrames={240}
      fps={30}
      width={1920}
      height={1080}
    />
  );
});
```

**⚠️ CRITICAL Remotion v4 Rules:**
1. Use `.tsx` extension (NOT `.ts`) for files with JSX
2. MUST use `registerRoot` + `Composition` API
3. ALWAYS pass `fps` to `spring()`: `spring({ frame, fps, from: 0.8, to: 1 })`
4. Use `useVideoConfig()` to get fps: `const { fps } = useVideoConfig()`
5. Render with composition name: `npx remotion render MyVideo out/video.mp4`

### Step 8: Start Dev Server
```bash
cd my-video && npm run dev
```
Server runs on http://localhost:3000

### Step 9: Preview & Iterate
- Open browser to preview
- Edit source files - hot-reloads automatically
- User reviews and requests changes

### Step 10: Render Final Video (when user asks)
```bash
npx remotion render index out/final-video.mp4
```

## Installation

```bash
# Install Remotion globally
npm install -g remotion

# Install dependencies for video projects
npm install lucide-react

# Install Scrapling (already in workspace skills)
pip install scrapling
```

---

## Agent Instructions

### When to Use Video Generator

**Use this skill when:**
- Creating promotional videos
- Making product demos
- Social media video content
- Animated explainers
- Commercials
- Any programmatic video content

**Do NOT use for:**
- Simple slideshows (use other tools)
- Video editing of existing footage
- Live streaming

---

## Default Workflow (ALWAYS follow this)

1. **Scrape brand data** (if featuring a product) using **Scrapling** (NOT Firecrawl)
2. **Create the project** in `output/<project-name>/`
3. **Build all scenes** with proper motion graphics
4. **Install dependencies** with `npm install`
5. **Fix package.json scripts** to use `npx remotion` (not bun):
   ```json
   "scripts": {
     "dev": "npx remotion studio",
     "build": "npx remotion bundle"
   }
   ```
6. **Start Remotion Studio** as a background process:
   ```bash
   cd output/<project-name> && npm run dev
   ```
7. **Expose via Cloudflare tunnel** so user can access:
   ```bash
   bash skills/cloudflare-tunnel/scripts/tunnel.sh start 3000
   ```
8. **Send the user the public URL** (e.g. `https://xxx.trycloudflare.com`)

The user will preview in their browser, request changes, and you edit the source files. Remotion hot-reloads automatically.

---

## Rendering (only when user explicitly asks to export)

```bash
cd output/<project-name>
npx remotion render CompositionName out/video.mp4
```

---

## Quick Start

```bash
# Scaffold project
cd output && npx --yes create-video@latest my-video --template blank
cd my-video && npm install

# Add motion libraries
npm install lucide-react

# Fix scripts in package.json (replace any "bun" references with "npx remotion")

# Start dev server
npm run dev

# Expose publicly
bash skills/cloudflare-tunnel/scripts/tunnel.sh start 3000
```

---

## Fetching Brand Data with Scrapling

**MANDATORY:** When a video mentions or features any product/company, use Scrapling to scrape the product's website for brand data, colors, screenshots, and copy BEFORE designing the video. This ensures visual accuracy and brand consistency.

### Using the Scrapling Script

```bash
# Run the brand data extraction script
bash skills/remotion-video-generator/scripts/scrapling.sh "https://example.com"
```

This returns structured brand data: brandName, tagline, headline, description, features, logoUrl, faviconUrl, primaryColors, ctaText, socialLinks, plus screenshot URL and OG image URL.

### Manual Scrapling Extraction

If the script isn't available, use Python directly:

```python
import json
from scrapling.fetchers import StealthyFetcher
from urllib.parse import urljoin
import re

url = 'https://brand.com'
page = StealthyFetcher.fetch(url, headless=True)
html = page.text

def resolve(u):
    return urljoin(url, u) if u and not u.startswith('http') else u

colors = list(set(re.findall(r'#(?:[0-9a-fA-F]{3}){1,2}', html)))[:5]

data = {
    'brandName': page.css('[property="og:site_name"]::text').get() or page.title(),
    'tagline': page.css('[property="og:description"]::text').get(),
    'headline': page.css('h1::text').get(),
    'description': page.css('[property="og:description"]::text').get(),
    'logoUrl': resolve(page.css('[rel="icon"]::attr(href)').get()),
    'faviconUrl': resolve(page.css('[rel="icon"]::attr(href)').get()),
    'primaryColors': colors,
    'ctaText': page.css('a[href*="signup"]::text').get(),
    'ogImageUrl': resolve(page.css('[property="og:image"]::attr(content)').get()),
    'screenshotUrl': f"https://image.thum.io/get/width/1200/crop/800/{url}"
}

print(json.dumps(data, indent=2))
```

---

## Download Assets After Scraping

```bash
mkdir -p public/images/brand
curl -s "https://example.com/favicon.ico" -o public/images/brand/favicon.ico
curl -s "${OG_IMAGE_URL}" -o public/images/brand/og-image.png
curl -sL "${SCREENSHOT_URL}" -o public/images/brand/screenshot.png
```

**Note:** Some S3 buckets block direct access. Use thum.io screenshot service as fallback.

---

## Core Architecture

### Scene Management

Use scene-based architecture with proper transitions:

```typescript
const SCENE_DURATIONS: Record<string, number> = {
  intro: 3000,      // 3s hook
  problem: 4000,    // 4s dramatic
  solution: 3500,   // 3.5s reveal
  features: 5000,  // 5s showcase
  cta: 3000,        // 3s close
};
```

### Video Structure Pattern

```typescript
import { AbsoluteFill, Sequence, useCurrentFrame, useVideoConfig, interpolate, spring, Img, staticFile, Audio } from "remotion";

export const MyVideo = () => {
  const frame = useCurrentFrame();
  const { fps, durationInFrames } = useVideoConfig();

  return (
    <AbsoluteFill>
      {/* Background music */}
      <Audio src={staticFile("audio/bg-music.mp3")} volume={0.35} />

      {/* Persistent background layer - OUTSIDE sequences */}
      <AnimatedBackground frame={frame} />

      {/* Scene sequences */}
      <Sequence from={0} durationInFrames={90}>
        <IntroScene />
      </Sequence>
      <Sequence from={90} durationInFrames={120}>
        <FeatureScene />
      </Sequence>
    </AbsoluteFill>
  );
};
```

---

## Motion Graphics Principles

### AVOID (Slideshow patterns)

- Fading to black between scenes
- Centered text on solid backgrounds
- Same transition for everything
- Linear/robotic animations
- Static screens
- Emoji icons — NEVER use emoji, always use Lucide React icons

### PURSUE (Motion graphics)

- Overlapping transitions (next starts BEFORE current ends)
- Layered compositions (background/midground/foreground)
- Spring physics for organic motion
- Varied timing (2-5s scenes, mixed rhythms)
- Continuous visual elements across scenes
- Custom transitions with clipPath, 3D transforms, morphs
- Lucide React for ALL icons (`npm install lucide-react`) — never emoji

---

## Transition Techniques

| Technique | Description |
|-----------|-------------|
| **Morph/Scale** | Element scales up to fill screen, becomes next scene's background |
| **Wipe** | Colored shape sweeps across, revealing next scene |
| **Zoom-through** | Camera pushes into element, emerges into new scene |
| **Clip-path reveal** | Circle/polygon grows from point to reveal |
| **Persistent anchor** | One element stays while surroundings change |
| **Directional flow** | Scene 1 exits right, Scene 2 enters from right |
| **Split/unfold** | Screen divides, panels slide apart |
| **Perspective flip** | Scene rotates on Y-axis in 3D |

---

## Animation Timing Reference

```typescript
// Timing values (in seconds)
const timing = {
  micro: 0.1-0.2,     // Small shifts, subtle feedback
  snappy: 0.2-0.4,    // Element entrances, position changes
  standard: 0.5-0.8,   // Scene transitions, major reveals
  dramatic: 1.0-1.5,  // Hero moments, cinematic reveals
};

// Spring configs
const springs = {
  snappy: { stiffness: 400, damping: 30 },
  bouncy: { stiffness: 300, damping: 15 },
  smooth: { stiffness: 120, damping: 25 },
};
```

---

## Visual Style Guidelines

### Typography

- One display font + one body font max
- Massive headlines, tight tracking
- Mix weights for hierarchy
- Keep text SHORT (viewers can't pause)

### Colors

- **Use brand colors from Scrapling scrape** as the primary palette — match the product's actual look
- Avoid purple/indigo gradients unless the brand uses them or the user explicitly requests them
- Simple, clean backgrounds are generally best — a single dark tone or subtle gradient beats layered textures
- Intentional accent colors pulled from the brand

### Layout

- Use asymmetric layouts, off-center type
- Edge-aligned elements create visual tension
- Generous whitespace as design element
- Use depth sparingly — a subtle backdrop blur or single gradient, not stacked textures

---

## Remotion Essentials

### Interpolation

```typescript
const opacity = interpolate(frame, [0, 30], [0, 1], {
  extrapolateLeft: "clamp",
  extrapolateRight: "clamp"
});

const scale = spring({
  frame,
  fps,
  from: 0.8,
  to: 1,
  durationInFrames: 30,
  config: { damping: 12 }
});
```

### Sequences with Overlap

```tsx
<Sequence from={0} durationInFrames={100}>
  <Scene1 />
</Sequence>
<Sequence from={80} durationInFrames={100}>
  <Scene2 />
</Sequence>
```

### Cross-Scene Continuity

Place persistent elements OUTSIDE Sequence blocks:

```tsx
const PersistentShape = ({ currentScene }: { currentScene: number }) => {
  const positions = {
    0: { x: 100, y: 100, scale: 1, opacity: 0.3 },
    1: { x: 800, y: 200, scale: 2, opacity: 0.5 },
    2: { x: 400, y: 600, scale: 0.5, opacity: 1 },
  };

  return (
    <motion.div
      animate={positions[currentScene]}
      transition={{ duration: 0.8, ease: "easeInOut" }}
      className="absolute w-32 h-32 rounded-full bg-gradient-to-r from-coral to-orange"
    />
  );
};
```

---

## Quality Tests

Before delivering, verify:

- **Mute test:** Story follows visually without sound?
- **Squint test:** Hierarchy visible when squinting?
- **Timing test:** Motion feels natural, not robotic?
- **Consistency test:** Similar elements behave similarly?
- **Slideshow test:** Does NOT look like PowerPoint?
- **Loop test:** Video loops smoothly back to start?

---

## Implementation Steps

1. **Scrapling brand scrape** — If featuring a product, scrape its site first
2. **Director's treatment** — Write vibe, camera style, emotional arc
3. **Visual direction** — Colors, fonts, brand feel, animation style
4. **Scene breakdown** — List every scene with description, duration, text, transitions
5. **Plan assets** — User assets + generated images/videos + brand scrape assets
6. **Define durations** — Vary pacing (2-3s punchy, 4-5s dramatic)
7. **Build persistent layer** — Animated background outside scenes
8. **Build scenes** — Each with enter/exit animations, 3-5 timed moments
9. **Open with hook** — High-impact first scene
10. **Develop narrative** — Content-driven middle scenes
11. **Strong ending** — Intentional, resolved close
12. **Start Remotion Studio** — `npm run dev` on port 3000
13. **Expose via tunnel** — `bash skills/cloudflare-tunnel/scripts/tunnel.sh start 3000`
14. **Send user the public URL** — They preview and request changes live
15. **Iterate** — Edit source, hot-reload, repeat
16. **Render** — Only when user says to export final video

## Troubleshooting

### Common Issues & Fixes

| Issue | Solution |
|-------|----------|
| `Expected ">" but found "schema"` | Use `.tsx` extension for files with JSX, not `.ts` |
| `useCurrentFrame() can only be called inside a component` | Use `registerRoot` + `Composition` API (see Step 7) |
| `"fps" must be a number, but you passed undefined to spring()` | Pass `fps` to spring: `spring({ frame, fps, from: 0.8, to: 1 })` |
| `Could not find composition with ID index` | Use composition name: `npx remotion render MyVideo out.mp4` |
| `Module build failed` | Ensure `react` and `react-dom` are in dependencies |
| Remotion not found | Run `npm install` in project directory |
| Hot reload not working | Ensure running `npm run dev`, not `npx remotion` directly |
| Brand colors not extracting | Some sites use CSS variables - check page source manually |

### File Extension Rules
- Use `.tsx` for files with JSX (components with `< tags >`)
- Use `.ts` for pure TypeScript files
- Entry point MUST be `.tsx` if it uses JSX

### Testing Your Video
1. Start dev server: `npm run dev`
2. Open http://localhost:3000
3. Make changes - auto-refreshes
4. Check composition in browser
