## Structure

### Hook (0-3s)
Pattern interrupt, curiosity gap, or bold claim. The viewer decides to stay or leave in 3 seconds.

### Context Bridge (3-15s)
Why the viewer should stay. Establish credibility and promise of value.

### Value Delivery (main body)
Chapters with mini-hooks at transitions to prevent drop-off. Each chapter delivers on a specific promise.

### CTA
Subscribe, like, comment prompt integrated naturally (not forced). Best placed after a value moment.

### End Screen (last 20s)
Teaser for the next video. Visual end screen elements.

## Best Practices
1. Script the first 30 seconds word-for-word
2. Use chapters (timestamps) for SEO and navigation
3. Thumbnail: one focal point, max 3-4 words, readable at 120px width
4. Title creates curiosity without misleading (clickbait kills trust)

## Anti-patterns
1. "Hey guys, welcome back to my channel..." (instant drop-off)
2. Intros longer than 15 seconds
3. Thumbnails with cluttered text or low contrast

## Quality Checklist
- [ ] Hook is scripted and compelling (first 3 seconds)
