The Story Behind This Prompt
Behind the rocks of one hidden cove, the water sparkles a little too brightly — because a mermaid family lives there, and today someone is about to see them for the very first time. Secret-encounter fantasy shorts win millions of hearts with wonder alone: the glimpse, the peek, the kindness, and the glowing gift left behind. MERMAID-OS V1 turns that gentle fairytale into one smart master prompt: you answer a few simple questions, choose whether you want one ready-made prompt for the whole video or a separate prompt for each scene, and it writes the complete story for you — wholesome, family-friendly and magical, with a viral pack of titles, caption and hashtags. It works with Seedance, Dola AI, Veo, Kling, Runway, Pika and any text-to-video AI tool, and it is made for YouTube Shorts, TikTok, Instagram Reels and Facebook Reels.
HOW TO USE:
- Copy the prompt: Scroll down to the code box at the bottom of this post and copy the full MERMAID-OS V1 prompt — every line, nothing skipped.
- Answer the 5 setup questions: Paste the prompt into a chatbot like ChatGPT (or straight into Seedance, Dola AI or any text-to-video AI tool) and it will ask you 5 simple questions: how long the video is, who discovers the cove, which mermaid family lives there, and what gift they leave behind — and the last one, how you want your final prompt. Pick A) one ready-made full prompt for the whole video, or B) a separate prompt for each scene. If you are ever unsure, just type "surprise me".
- Get your video prompt: The system builds everything for you. With the ready-made mode you get ONE prompt for the whole video — paste it once and the complete video is made in one go. With the scene mode you get one ready prompt per scene, in the perfect order: the cove and the tail splash, the peek behind the rocks, the meeting, the gift, and the goodbye wave.
- Make the video: Paste the prompt into your AI video tool and generate. If you picked the scene mode, make the clips one by one in the same order. Check each clip quickly: the family, their hair and tail colours and the cove must stay the same in every shot.
- Join the clips: If you made separate scene clips, join them in the same order in any simple video editor. The final shot is your ending — and your thumbnail.
- Post it and grow: Use the ready titles, caption and hashtags that come with the prompt — they are made for YouTube Shorts, TikTok, Instagram and Facebook Reels. One new ocean secret a day is how this fairytale grows. And if you are a complete beginner, do not worry: every result also includes a simple best-tools guide that shows you exactly which tools to use and how, step by step.

==================================================
HOW THIS SYSTEM WORKS
==================================================
Paste this whole prompt into your AI video tool or chatbot. It will first ask you 5 quick setup questions (STATE [0]). Answer them, or type "surprise me" on any question. The last question is the OUTPUT MODE: you choose ONE ready-made full prompt for the whole video (paste once — the complete video is made in a single generation), or a separate prompt for each scene. It then builds your video prompt(s) with the full discovery arc, consistency locks and sound design — plus a viral pack of titles, caption and hashtags, and a simple best-tools guide for beginners.
==================================================
STATE [0] — SETUP QUESTIONS (the AI asks these first)
==================================================
Q1 — VIDEO LENGTH: How long is the video?
A) 10 seconds (the glimpse + the wave)
B) 20 seconds (discovery → meeting → gift)
C) 30 seconds (the full secret story)
D) 60 seconds (a two-part-feeling episode in one video)
Or: surprise me
Q2 — THE DISCOVERER: Who finds the cove?
A) A curious young girl exploring the rocks
B) An old fisherman who finally sees what he always suspected
C) A kind snorkeler/diver at dawn
D) A little brother and sister together
Or: surprise me
Q3 — THE FAMILY: Who lives in the cove?
A) A mermaid mother with two small mermaid children
B) A whole mermaid family — parents, children, a grandmother
C) Three mermaid sisters
D) A mermaid mother and one baby
Or: surprise me
Q4 — THE GIFT: What do they leave behind?
A) A glowing pink seashell
B) A perfect pearl resting on a rock
C) A tiny bottle with starlight inside
D) A shell necklace placed gently on the sand
Or: surprise me
Q5 — OUTPUT MODE: How do you want your final video prompt? (Read both carefully — then pick one)
A) READY-MADE FULL PROMPT: ONE single ready-to-paste prompt for the WHOLE video at the length you picked above. Paste it once into your video tool and the complete video is generated in one go — no joining clips. Best for beginners and one-click results.
B) SCENE-BY-SCENE PROMPTS: a separate ready-to-paste prompt for EACH scene, numbered and in order. You generate the scenes one by one and join them yourself. Best for full control and the cleanest quality.
Or: surprise me (the AI picks A for 10–20 seconds, B for 30–60 seconds)
After the answers, the AI locks the choices: same discoverer, same mermaid family (same hair colours, same tail colours), same cove — start to finish.
==================================================
THE FAMILY LOCK
==================================================
THE MOTHER: long teal-blue hair with a small white flower, a shimmering teal tail, a modest seaweed-and-shell fairytale top. Gentle, protective, kind eyes.
THE CHILDREN: small, cute, same teal hair family resemblance, tiny shimmering tails, always close to their mother, always safe and happy.
THE DISCOVERER: locked by Q2 — ordinary clothes, a small bag, wonder on their face. They never enter deep water and never chase the family.
RULE: hair, tails and faces never change; the family is always wholesome and modestly styled — a children's fairytale come to life.
==================================================
THE STORY ARC (locked scene order)
==================================================
SCENE 1 — THE COVE (hook, first 2 seconds): sparkling turquoise water in a rocky cove... and for one instant, a shimmering tail splashes and is gone. The discoverer's head turns. What was that?
SCENE 2 — THE PEEK: hiding behind the rocks, the discoverer watches, amazed: the mermaid family playing in a rock pool — mother braiding a child's hair, gentle laughter, tails sparkling in the sun.
SCENE 3 — THE MEETING: eyes meet. One frozen second... then the mother smiles kindly and waves the discoverer closer (or the children wave first). Wonder, not fear.
SCENE 4 — THE GIFT: the family leaves the gift from Q4 on a wet rock, gleaming — a thank-you for keeping their secret. The discoverer picks it up with both hands, glowing with joy.
SCENE 5 — THE GOODBYE (finale): tails splash into the golden water as the family waves and slips away under the waves. The discoverer holds the gift to their heart, smiling at the sea. Freeze on this frame — it is the thumbnail.
Duration scaling:
- 10s: Scenes 1, 3, 5 only (glimpse, meeting, goodbye).
- 20s: all 5 scenes, tight cuts.
- 30s: all 5 scenes with a longer pool-play sequence.
- 60s: a fuller visit — the discoverer returns at sunset, a longer family moment, the gift, the goodbye, and one last tail splash far away.
==================================================
CONSISTENCY CHECKLIST (the AI checks every scene against this)
==================================================
[ ] Mother, children and discoverer keep the same faces, hair and tail colours in every scene
[ ] Tails are elegant and fish-like — smooth swimming motion, no legs appearing, no morphing
[ ] Water stays clear turquoise in daylight settings — same cove, same rocks, same light
[ ] The children always stay close to the mother and look happy and safe
[ ] Styling stays modest and family-friendly in every frame
[ ] The gift is identical in every shot — same shell/pearl/bottle, same glow
[ ] Swimming motion is graceful and slow — no fast scary movements, no storms unless picked
[ ] No text, logos or watermarks anywhere in the video
==================================================
AUDIO ARC (ocean sounds + gentle wonder, no dialogue)
==================================================
- 10s: waves and gulls → one magical splash → a soft sparkle sound on the gift → happy sigh
- 20s/30s: full cove ambience, children's distant laughter, gentle splashes, a soft magical chime for the gift, warm emotional music very low under the goodbye
- 60s: the full soundscape across two visits; the final far-away splash echoes like a promise
Rule: real ocean sounds first. Music, if used, is gentle fairytale style and always quiet.
==================================================
CAMERA RULES
==================================================
- Dreamy cinematic camera: slow glides over the water, gentle push-in on the peek and the goodbye
- Faces and expressions must read clearly — wonder is the emotion of this series
- Vertical 9:16 for Shorts/TikTok/Reels unless the user picks horizontal 16:9
- Bright sparkling daylight or golden sunset — never dark or stormy unless that setting was picked
==================================================
NEGATIVE PROMPT (always attach)
==================================================
no scary mermaids, no dark mood, no storms, no revealing outfits, no romance, no kissing, no changing faces, no changing tail colours, no legs on mermaids, no morphing, no extra fingers, no text, no logo, no watermark, no sad ending
==================================================
OUTPUT MODE RULES (the AI follows these exactly)
==================================================
MODE A — READY-MADE FULL PROMPT: deliver EXACTLY ONE prompt that contains the whole video — every scene in order with its timing written inside it (0–2s the cove, 2–6s the peek...), with the family locks and the negative prompt folded in. The user pastes it ONCE and gets the full video in a single generation. NEVER split Mode A into separate prompts.
MODE B — SCENE-BY-SCENE PROMPTS: deliver one separate ready-to-paste prompt per scene, numbered, in the locked scene order. Each scene prompt repeats the family, the tails and the cove in full, so every generated clip matches the others perfectly.
Whichever mode the user picks, the viral pack below is always delivered too.
==================================================
VIRAL OUTPUT PACK (the AI delivers this with every video prompt)
==================================================
1. The final copy-paste video prompt — delivered in the chosen OUTPUT MODE (Mode A: one ready-made full prompt for the whole video / Mode B: one prompt per scene, in order)
2. FIVE fresh encounter ideas for the next videos (new coves, new gifts, new seasons)
3. FIVE viral titles (secret + wonder words: "She Found A Mermaid Family", "The Shell That Glows At Night"...)
4. ONE ready caption with a question that invites comments ("Would you keep the secret?")
5. Hashtags: #mermaid #ocean #fantasy #secret #viralshorts #fairytale
6. CTA line: "Follow for a new ocean secret every day"
==================================================
BEST TOOLS + BEGINNER GUIDE (the AI prints this with every output)
==================================================
Completely new to AI video? Follow these 3 simple steps:
STEP 1 — RUN THIS MASTER PROMPT in a free chatbot: ChatGPT, Claude or Gemini. Paste this whole master prompt there, answer the 5 questions, and the chatbot builds your video prompt(s) for you.
STEP 2 — MAKE THE VIDEO in a video tool. The best tools for this style: Seedance and Dola AI (the easiest to use), Veo (top quality), Kling, Runway and Pika. Open the tool, choose text-to-video, paste the prompt from Step 1, set the size to vertical 9:16, and press generate.
STEP 3 — YOUR MODE: Mode A (ready-made) = paste the one full prompt once and the whole video is made in a single go. Mode B (scene-by-scene) = generate each scene prompt one by one, download every clip, and join them in order in a free editor — CapCut is the easiest.
Tip: if your video tool only makes short clips, use Mode B and join the clips — that is exactly how the long videos are made.
==================================================
GOLDEN RULES
==================================================
1. The tail splash is the hook — one glimpse in the first 2 seconds.
2. Wonder, never fear — this family is kind, and the secret is safe with us.
3. Same family, same tails, same cove — start to finish.
4. End on the gift held to the heart. Every time.
