Short-form feeds give you two seconds. Not “about two seconds” — two. If the first beat of your UGC ad hasn’t given a viewer a reason to stay, the thumb has already moved, and everything you generated after second two ran for nobody. That’s why the hook isn’t a part of the script; functionally, it is the script, and the body and CTA exist to cash the check it writes.
Below are ten hook formulas that consistently survive contact with real feeds, each with a prompt-ready dialogue line you can drop into a Veo 3.1, Seedance 2.5, or Kling prompt. They’re the same hook grammar our prompt generator draws on when Smart Suggestions picks an angle for your product — use these when you want to steer the angle yourself.
What every hook needs (regardless of formula)
- Spoken, not captioned. UGC hooks are said to camera. On-screen text is an ad tell — our prompts ban it in the negatives.
- Product or problem visible at second zero. The frame must justify the words immediately.
- Casual delivery. Write contractions and filler energy (“okay so—”, “honestly?”) into the quoted line; announcer cadence kills the illusion faster than bad lighting.
- One hook per ad. Stacking two hooks halves both.
The ten formulas
1. The direct question
Ask the viewer the thing the product answers. Questions hijack attention because brains auto-answer them.
Dialogue: "Why does nobody talk about how bad reusable bottles smell after a week?"
Best for: problem-aware audiences. Pair with a “relatable problem” body beat.
2. The bold claim
One confident, specific, defensible statement — not hype, precision.
Dialogue: "This is the only kitchen thing I've bought twice — one for me, one for my mom."
The second half of the claim is doing the work: “bought twice” is checkable human behavior, not marketing math.
3. The relatable frustration (cold open on the problem)
Open on the annoyance itself, mid-happening. The viewer recognizes their own life before they realize it’s an ad.
Action: She yanks at a tangled phone cable that's caught on the drawer handle, exhales through her nose. Dialogue: "Every. Single. Morning. — okay, so someone finally fixed this."
This is the natural hook for the problem→solution format; the pivot line lands at the 2–3 second mark.
4. “I was wrong about this”
The skeptic-convert arc compresses social proof into one sentence, because admitting error reads as honesty.
Dialogue: "I genuinely thought these were a scam — I need to apologize to whoever invented them."
Cast an older, no-nonsense persona for this one; the less like an influencer the speaker seems, the harder it hits.
5. The specific number
Numbers with texture beat superlatives: days used, dollars saved, attempts failed.
Dialogue: "Day fourteen of using this every morning — the dull patch on my chin is just… gone."
Modest timeframes (“two weeks”, “day fourteen”) read as true where “overnight results” reads as an ad. Never invent statistics — a personal count is believable precisely because it’s small.
6. “Don’t buy this unless…”
Reverse-selling filters the audience and flatters the ones who stay.
Dialogue: "Don't get this candle if you like your house smelling like nothing, I guess."
Keep the tone playful, not smug; the wink is the point.
7. The overheard secret
Lower the volume, lean in, and the feed leans in with you. Intimacy is a pattern interrupt in a loud feed.
Dialogue: (quieter, closer to the mic) "Okay, I'm not supposed to know this works this well for the price." Audio: phone-mic voice, close breath, quiet room tone.
8. The instant demo (show the wow first)
For products with a visible payoff, the hook can be an action, not a sentence — the words arrive as reaction.
Action: The product is already working at second zero — the spray lifts the stain in one pass. Dialogue: "Wait— one pass? One pass."
This is Seedance 2.5 territory: physics doing the persuading. See the demo templates in the library for full versions.
9. The comparison you weren’t supposed to say
Position against a shared reference without naming brands (never name brands you weren’t given).
Dialogue: "This does what the fancy one does, and I checked my bank account after buying it — still fine."
10. The unboxing cold-react
The package is the hook: already in frame, already being opened. Genuine first-reaction energy carries the first two seconds without a single scripted claim.
First frame: hands lifting the lid of a plain shipping box, product logo just becoming visible. Dialogue: "Oh— okay, the packaging alone… oh this is nice."
Kling’s first-frame strength makes it the natural model here.
Matching formula to format
Testimonials pair with questions, numbers, and the skeptic-convert. Problem→solution owns the cold-open frustration. Demos want the instant-demo and bold-claim hooks. Unboxings barely need words at all. If you’re unsure, generate once with Smart Suggestions on — the tool reads your product photo and picks the pairing — then regenerate with a different angle and compare hooks side by side; regeneration deliberately changes the hook framing while keeping the authenticity rules locked.
Writing the two seconds into the prompt
A hook only exists if the prompt forces it early. Three mechanical rules:
- Put the hook line first in the quoted dialogue and keep the whole script 20–35 words for an 8–10 second clip — there’s no room for a warm-up sentence.
- Stage the frame for second zero: product in hand, problem mid-happening, or box mid-open. If the hook needs context the frame doesn’t show, the frame is wrong.
- Protect it with negatives: no on-screen text, no announcer voice, no polished ad look — the hook must sound found, not produced.
Pair the hook with the right voice
A hook formula is only half the casting decision — the same line lands differently in different mouths. The skeptic-convert (“I was wrong about this”) needs someone with no influencer polish: a man in his 50s, a no-nonsense woman in her 40s. The overheard secret suits fast, very-online twenty-something energy. The specific number belongs to the warm, busy, practical persona — someone who counts days because their schedule makes them. When you write the persona into the prompt, describe delivery, not beauty: “honest, zero hype, talks like she’s saving you money” gives the model direction a headshot never could. Mismatched pairings are why technically good hooks die: a bold claim in announcer cadence is just an ad again.
Test hooks, not videos
When a UGC ad underperforms, the instinct is to regenerate the whole thing. Resist it. Hold the persona, setting, and body constant and swap only the hook formula — question against number against skeptic-convert — and you’ll learn which angle your audience answers, which is knowledge that outlives any single clip. Watch the metrics that actually measure hooks: 3-second view rate and completion rate tell you whether second two did its job; click-through tells you about the CTA, a different organ entirely. One formula winning across two different products is a signal about your audience worth keeping.
