Viral shorts live or die in the first second. Prompts differ from regular video: bold opening + single simple action + 9:16 + high-contrast palette. Below: 10 hook-shot templates.

What a high-quality prompt should contain

Viral short prompts need 5 layers:

  • Aspect: 9:16 vertical — horizontal hooks die on vertical platforms
  • Bold opener: close-up of eyes opening / single drop hits water / sneaker landing
  • Single action: 3–4s sweet spot, no stacking
  • High-contrast palette: deep contrast against black background / vibrant palette
  • Slow-mo / freeze: slow-motion expanding bloom / freeze on impact — rhythm

10 copy-ready prompt templates

1. Explosive opener

Best for: TikTok / Douyin hook

Close-up of a person\`s eyes opening suddenly, sharp focus, dramatic side rim light, deep contrast against black background, 9:16 vertical, 3 seconds

2. Color burst

Best for: Product reveal, brand intro

A single drop of bright red ink hits clear water, slow-motion expanding bloom, plain white background, ultra-sharp, 9:16, 3 seconds

3. Satisfying pour

Best for: Food / oddly-satisfying content

Close-up of hands quickly pouring colorful candy into a bowl, top-down angle, vibrant palette, snappy motion, 9:16 vertical, 4 seconds

4. Sneaker drop

Best for: Streetwear / athletic brands

A pair of sneakers landing on wet pavement with a splash, slow-motion, neon street reflections, 9:16, 3 seconds

5. Ramen lift

Best for: TikTok food, restaurant promo

Slow push-in on a steaming bowl of ramen, chopsticks lifting noodles, warm tungsten lighting, 9:16 vertical, 4 seconds

6. Fashion spin freeze

Best for: Apparel brand, micro-drama intro

A model spins quickly causing skirt to flare, slow-motion freeze on flare, single key light, fashion ad aesthetic, 9:16, 4 seconds

7. Surprise unboxing

Best for: Product launch, holiday promo

Top-down POV hands opening a small gift box with sparkles flying out, ultra-bright lighting, 9:16, 3 seconds

8. Stat skyrocket

Best for: SaaS / growth content

Quick zoom into a smartphone screen showing a bright animated chart bar rapidly rising, neon glow, 9:16, 4 seconds

9. Sprint stop

Best for: Athletic brands, hype content

A person sprints toward camera and stops just before frame, dramatic motion blur, golden sunset lighting, 9:16, 4 seconds

10. Curtain reveal

Best for: Lifestyle, product reveal

POV of opening a curtain to reveal a bright sunlit room, lens flare, warm golden palette, slow steady motion, 9:16, 4 seconds

Common mistakes

  • Using 16:9 — cropped on vertical platforms
  • Slow lead-in (“a quiet morning city…”) — scrolled before payoff
  • Action too complex — viral shorts need instant read
  • Flat palette — disappears in the feed
  • Going past 5s — one hook shot = 3–4s

How to push results further

  • Eye-grabbers: liquid splash, burst of light, slow-motion impact
  • Add ultra-sharp and deep contrast — small-screen visibility
  • Two-color palette (red/blue, yellow/black) beats rainbow
  • For before/after: generate two clips, cut together — single-prompt transitions fail
  • Pair with a Suno-generated 808-drop hook for instant TikTok production value

Practical depth notes

Use these prompts as starting points, not final answers. For Viral Short-Form AI Video Prompts: 10 Hook Templates (9:16), the useful extra work is to replace every generic placeholder with a real constraint: audience, channel, length, brand voice, examples to imitate, and examples to avoid. Run at least two versions with different constraints, then compare the outputs side by side instead of accepting the first polished response.

A good result should pass three checks: it is specific enough that another person could reuse it, it avoids vague praise or filler, and it gives you an editable artifact rather than a broad suggestion. If the output feels generic, add one concrete reference, one forbidden pattern, and one measurable success criterion before rerunning the prompt. Before saving a prompt as reusable, test it on one realistic input and one edge case. The realistic input proves the template can produce the normal deliverable; the edge case shows whether it handles messy constraints, missing context, or an unusual audience. Keep the better output, but also keep the failed version with a note on what was missing. That small failure log is what turns a prompt collection from a list of nice sentences into a practical working library. One final check: compare the finished result against the original goal in a single sentence. If that sentence is hard to write, the output is probably polished but unfocused. Tighten the goal, remove decorative language, and rerun only the weak section instead of regenerating the entire piece.

FAQ

Q: Captions on 9:16 — how to leave room?

A: Prompt large empty space at bottom for caption so the subject doesn’t clash with overlay text.

Q: Can I generate a before/after viral transition in one prompt?

A: No. Generate two clips, cut. Transition prompts are still unstable.

Q: TikTok recompression destroys my AI clip — fix?

A: Export at 15–20 Mbps, 1080×1920 — survives second-pass compression better.

Q: My AI shorts get throttled as “low quality” — fix?

A: Hybrid edit: AI for transitions / B-roll + human voiceover / live shots + captions. Pure-AI content gets throttled; mixed bypasses the filter.
