This book transformation AI video prompt starts with a quiet evening. You lie on a picnic blanket in a park, with iced coffee and a bag of oranges, and open a book. Then the world around you turns into the story.

The grass dies into cracked earth. The trees turn into black stone spires, and the blanket becomes a torn war banner. A dragon crashes down behind you, and two armies fight a few metres from your feet. You keep reading. When you close the book, everything flows back into the park.

It is 30 seconds in one take. You need one clear photo of yourself. This page has three prompts: one for a character sheet, one for a park picture to plan the look, and the video prompt.

The whole process

  1. Pick one clear photo of your face, in good light.
  2. Make a character sheet of you with the first prompt, in GPT Image 2.
  3. Optional: make a park picture with the second prompt, to see the scene before you spend video credits.
  4. Open Vosu, go to video and pick Seedance 2.5. Add the sheet as @Image1.
  5. Set 30 seconds and 9:16. Paste the video prompt and generate.

Make the character sheet

The video is 30 seconds long and the camera moves around her a lot. One photo is not enough to keep the face and hair the same from every side. So first make a character sheet: you from the front, the side and the back, with close ups of the face.

Open an image model that takes a reference picture. We used GPT Image 2 on Vosu. Add your photo, set the shape to 3:2 and paste this prompt. Your face and hair come from the photo. The clothes are written in the prompt, and they are the same clothes the video asks for.

Character sheet: GPT Image 2, one reference photo, 3:2

Use Image 1 as the only source for the person’s identity. Create a photographic character reference sheet of this person.

IDENTITY — IMAGE 1: Keep exactly: face shape and bone structure, eye shape and eye color, eyebrows, nose, lips, skin tone, freckles and moles, age, body build, hair color, hair length and hair texture. Do not beautify, slim or redesign the person. The same person must be recognizable in every panel.

HAIR: Keep the hair color and length from Image 1. Worn loose, with a natural part, visible strands and flyaways.

CLOTHES:

  • a plain black sleeveless top, fitted, soft cotton jersey
  • faded light-blue straight-leg jeans, worn denim with natural creases
  • bare feet No jewelry that is not visible in Image 1.

LAYOUT: One character sheet on a landscape 3:2 canvas, clean white studio background, thin white gutters between panels. Left: a large head-and-shoulders portrait, facing the camera. Center: three full-body views, front, side profile and back, head to feet fully visible. Right: two close-ups of the face, three-quarter view and side profile. Bottom row: small detail crops of the eye, the lips, the hair ends, the top and the jeans.

PHOTOGRAPHY: Real studio photograph, 85mm lens, soft even light, true-to-life color, real skin texture with pores, no airbrushing.

CONSTRAINTS: One person only. Same person, same clothes in every panel. No text, no labels, no numbers, no watermark, no illustrated or 3D look.

Image 1 is your photo. The clothes come from the prompt.

This is the sheet we used. Ours shows a green top, black jeans and sneakers, because it was made earlier for other videos. It still worked: the video prompt describes the clothes in words, and the model followed the words.

A character sheet of a woman with long wavy hair that goes from dark burgundy roots to copper orange ends, green hazel eyes and freckles. A large face portrait on the left, three full body views in a dark green top, wide black jeans and white sneakers in the middle, two face close-ups on the right, and small crops of the eye, lips, hair, earring and watch along the bottom, all on a white background.
@Image1 The character sheet: face, hair and body from every side

Check the hair before you move on. Long two-tone hair is the first thing to drift in a long video. If the colors change between panels, make the sheet again.

02

Optional: make the park picture

This step is not needed for the video. The video prompt describes the park in words, and the sheet is the only reference. But a picture of the park helps you see the scene and the light before you spend video credits on 30 seconds.

Use the same image model, add your character sheet, set 3:4 and paste this prompt.

Park scene: GPT Image 2, character sheet as reference, 3:4

Use Image 1 only for the woman’s face, hair and body. Do not use the white background, the layout or the clothes of the sheet.

A candid photo in a city park at golden hour. The woman from Image 1 lies on her back on a cream fringed picnic blanket on deep green grass, her head on a linen bolster pillow, holding an open hardcover book above her face and reading. She wears a black sleeveless top, faded light-blue jeans and is barefoot. Her long hair spreads over the pillow.

On the blanket next to her: a plastic cup of iced coffee with a straw and a net bag of oranges.

Tall leafy trees behind her, a low amber sun, long soft shadows on the grass, a few fallen leaves. Far in the background, soft out-of-focus people sitting on the grass.

Camera: 50mm lens at a low angle from her feet side, shallow depth of field, natural color, light film grain, real photograph.

No text, no watermark, no illustrated look.

Image 1 is your character sheet. Use it to check the look of the scene.

This is the picture we made. The blanket, the pillow, the coffee and the oranges are the same objects the video prompt names.

A woman with long red orange hair lies on a cream fringed blanket in a park at golden hour, head on a linen pillow, reading an open book above her face. She wears a black top and light blue jeans. Next to her are an iced coffee with a straw and a net bag of oranges, with tall trees and soft sunlight behind her.

Set it up and generate

Open Vosu, go to video and pick Seedance 2.5.

Add your character sheet as the only reference, so it is @Image1. Set the length to 30 seconds and the shape to 9:16. Paste the prompt below. It is the exact prompt that made the video above.

Elaria is the name of our character. You can leave it as it is, or change it to your own name everywhere in the prompt. The model only uses it as a label.

Book transformation, dragon war: Seedance 2.5, 30 seconds

[Goal] 30s photorealistic live-action fantasy. Elaria lies on a picnic blanket in a park at golden hour, opens a book, and the world physically transforms around her into a dragon war — ground, objects, light and sky — while she stays in place reading. She closes the book and it changes back. She is inside the battlefield, not watching it from outside.

[Elaria] @Image1 — face, freckles, green-hazel eyes, long wavy hair, dark burgundy roots into copper-orange ends, centre part. Do not use the white studio background or the upright posture. Black sleeveless top, faded light-blue jeans, bare feet. She lies on her back the whole video — never sits up, never moves off her spot. Her face, hair, clothes and position are the ONLY things that never change.

[Park — start and end] Golden hour. Deep green grass, tall leafy trees, low amber sun, long shadows. On the grass: a cream fringed picnic blanket, a linen bolster pillow under her head, a plastic cup of iced coffee, a net bag of oranges. One thick dark hardcover book.

[Transformed world] Same space, changed object by object: grass dies into cracked grey earth, trees blacken into bare stone spires, the blanket becomes a torn mud-stained war banner, the pillow a leather bedroll, the cup a dented metal camp cup, the net bag a coarse twine one. Black storm above, orange ground fire, white lightning. Beyond her: two armies on scorched ground, burning towers, and near-black dragons with oxblood wings fighting through the storm.

[Rule] Every change starts at the book and at the ground under her body and spreads outward to the horizon — never the reverse. Nothing is fenced off; the ground she lies on changes too.

[Camera] Low, at ground level, inside the space. Foreground objects pass through: a spear, running legs, smoke. One camera move per stage.

0-5s — Warm park. She picks up the book beside her hip, opens it, starts reading. Camera glides low along the blanket past the coffee cup.

5-11s — She turns a page. Green drains from the grass starting under her shoulders and races outward. Blanket tears into a banner, pillow into a bedroll, cup tips and becomes metal, trees go black and bare, sky closes to grey. Camera pulls back low so dead earth spreads past her on both sides. She glances at the grey ground by her hand, then reads on. End: no green anywhere; she lies on a banner on cracked earth, same clothes, same pose.

11-18s — She turns a page. Two dragons collide overhead and one crashes down 15m away. The ground jolts under her; grit and ash hit her jeans and the page; her hair whips. It climbs away. Camera arcs low around her past a planted spear and smoke. Sky darkens to storm blue-black, underlit orange. She grips the book, brushes ash off the page, smiles slightly.

18-25s — She turns a page. Two armies collide and the fight runs through her space — soldiers sprint past a few metres from her head and feet, never looking at her. Dozens of dragons fight above. Darkest point: near-black storm, orange fire below. Camera rises once at the end into a high wide — she is a small figure lying in the middle of a burning field.

25-30s — She closes the book. Everything reverses from under her outward: green floods back from beneath her shoulders, the banner softens into the blanket, bedroll into pillow, cup upright, spires back into trees, storm drawn into the book, amber light returns. Camera descends to the same low view as 0-5s. She rests the book on her chest and breathes out. End: exactly the opening park — same trees, same objects, same positions. One ash flake lands on the cover. Her hair moves once in wind that is gone.

[Dragons] Two hind legs, wings as forelimbs, no front legs. Heavy shoulders, long tail, plausible wing structure. They move like heavy animals, not weightless CGI.

[Consistency] Elaria is the anchor — identical face, hair, clothes and pose in every stage, head at the right of frame, camera always on the same side. One book. Soldiers never look at or touch her. The 0-5s and 25-30s park must match exactly.

[Style] Photorealistic live-action. Natural skin, shallow depth of field, heavy film grain, volumetric atmosphere. Hair, cloth and dust react physically. No glossy CGI, no game rendering, no on-screen text.

Your character sheet is @Image1, the only reference. Set 30 seconds and 9:16.

The [Elaria] line describes our hair: burgundy roots, copper ends, green-hazel eyes. Change it to your own hair and eye color, so the words and the sheet agree.

Why this prompt works

She is the anchor. The prompt says her face, hair, clothes and pose are the only things that never change, and that she lies on her back the whole time. With one fixed point, the model is free to change everything else around her.

The change happens object by object. The prompt names each park object and what it becomes: the blanket a war banner, the pillow a bedroll, the cup a metal camp cup. That is why the transformation looks planned and you can follow it with your eyes.

Each stage starts with “She turns a page”. The page turn gives the model a clear moment to start the next change, so the story moves in steps that match the reading.

The camera stays low, at ground level, and passes a spear, legs and smoke in the foreground. That puts you inside the battle. A high camera would make the war look like a backdrop.

The end mirrors the start. The prompt asks for exactly the opening park, the same low view and one ash flake on the cover. So the reel loops well, and the ash tells the viewer it really happened.
