What Makes a Clip Go Viral From a Long Video?

If it leads with a strong hook, holds tension, lands one clear point, and ends clean.
Open with the payoff or the bold line. Add a pattern break every 2 to 3 seconds. Use B-roll to reset attention. Ask for a follow when energy peaks, not at the very end.
Hook Formulas
- Problem then promise
- Hot take, then proof
- Question then answer
Pattern Breaks
- Jump cuts and punch-ins
- Text cards or emojis
- Sound hits or whooshes
CTA Placement
- Add mid-roll follow or subscribe
- Tease the next clip
How do you Repurpose One Long Video Across Reels, TikTok, and Shorts?

Platform Tweaks
- Hook text style and length
- Music library rules per platform
- Hashtag sets by niche
