# Short-Form Converter

Transform long-form content into viral short-form clips.

## Short-Form Platform Specs

| Platform | Max Length | Optimal | Aspect Ratio | Audio |
|----------|-----------|---------|--------------|-------|
| TikTok | 10 min | 15-60 sec | 9:16 | Critical |
| YouTube Shorts | 60 sec | 30-45 sec | 9:16 | Important |
| Instagram Reels | 90 sec | 15-30 sec | 9:16 | Critical |
| Facebook Reels | 60 sec | 15-30 sec | 9:16 | Important |

## Viral Moment Identification

### What Makes a Clip Viral-Worthy?

```
✅ STRONG VIRAL INDICATORS:
1. Emotional peak - Surprise, shock, joy, anger
2. Unexpected twist - Plot reversal, revelation
3. Valuable insight - "Aha moment", key takeaway
4. Relatable moment - "This is so me" content
5. Controversial take - Debate-starting opinion
6. Satisfying conclusion - Before/after, completion
7. Funny moment - Genuine humor, reaction

❌ WEAK CLIP MATERIAL:
- Long setup without payoff
- Inside jokes requiring context
- Technical explanations without visual
- Slow-paced segments
- Content requiring full video context
```

### Clip Selection Process

```
STEP 1: Timestamp key moments from long video
- Mark ALL emotional peaks
- Note all "quotable" statements
- Identify visual highlights
- Flag unexpected moments

STEP 2: Score each moment (1-10)
- Hook potential: Does it grab in 1 second?
- Standalone value: Makes sense without context?
- Engagement likelihood: Will people comment/share?
- Platform fit: Right vibe for TikTok/Shorts/Reels?

STEP 3: Select top 3-5 moments for clips
- Prioritize variety (don't all same type)
- Ensure each has different hook angle
```

```

```

## Editing Tips for Conversion

✅ DO:
- Add captions (85% watch muted)
- Use jump cuts to remove dead space
- Add b-roll or visual variety
- Include text overlays for key points

❌ DON'T:
- Just crop and post (feels lazy)
- Keep long pauses/transitions
- Use horizontal clips (except split-screen)
- Ignore platform-specific features
- Post same exact clip everywhere
- Forget the CTA
```
