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
