Short-Video Hooks: First 3 Seconds of AI Voiceover

People decide in about 3 seconds whether to keep watching. The opening line is not an introduction — it is a hook.

Five hook types

1. Contrast: “Would you believe this noodle shop hid for 30 years?”
2. Loss: “If you miss this, your videos keep getting buried.”
3. Result first: “Three words doubled my completion rate.”
4. Question: “Does your narration sound like homework?”
5. Command: “Don’t scroll — give me 10 seconds.”

A 15-second structure

1. 0–3s: hook
2. 3–10s: one vivid detail
3. 10–15s: call to action

Do not open with your brand story.

AI pacing tips

• Hooks about 10–15% faster

• Layer emotion tags at line start

Common mistakes

• Opening with “Hi, today I will talk about…”
• Too many facts in 3 seconds
• Flat tone with no hook energy
