Step 1 · The idea

The trend was a study.
Not a template.

It started with an Instagram reel: the camera glued to the ground, rising from the feet, objects hanging in mid-air. I never sent that video to the AI. I only used it to study direction: where the camera starts, how long it holds on each thing, what makes your eye follow.

The idea that became mine

A woman walks through a plaza, serious, holding a Jessli shopping bag. Someone bumps into her. The necklace clasp springs open, the chain comes off her neck and floats in the air. Time drops to 10% and the camera circles all the way around her, descending, stopping in macro on each piece: necklace, earring, bracelet, the hand letting go of the bag. Time returns to normal and the bag lands with the logo facing the lens.

Copying a trend's vibe gets you the same video as everyone else. Understanding what the camera is doing lets you make your own.

Step 2 · The references

5 images.
Each with one job.

In Seedance, each image becomes a tag in upload order: the first is @image1, the second @image2, and so on. They all follow the same rule: neutral grey background, one thing per image, catalog lighting. The character came as a 3-panel sheet so the AI knows her from any angle.

Pink Jessli Acessórios shopping bag with a green bow
@image5

Shopping bag

Blush paper, cotton handles and a green satin bow. The logo had to be spelled right in the final frame.

Step 3 · The request

I didn't ask for a nice video.
I directed the scene.

I asked Claude for the prompt, but the same request works in ChatGPT, Gemini or whatever text AI you already use. The difference isn't the tool, it's what you give it before asking for anything:

The idea written as visible action, from the first second to the last.
The 5 images in upload order, with what each one is.
Format and length: vertical, 24 seconds, one take with no cuts.
How the camera moves and in what order it reaches each piece.
Where time slows down and where it returns to normal.
What could not change: her face, the shape of each piece and the logo spelled right.

Describe what the camera sees, not what you want people to feel.

Use the same structure in your request

SCENE CONTEXT
A young woman walks alone down a sunlit pale-stone plaza walkway toward the camera, serious, eyes forward, never looking at the lens, a blush-pink shopping bag hanging from her left hand. A man crossing from camera-right clips her shoulder; the clasp at the back of her neck springs open and the gold chain comes off her body completely, floating free in the air as a loose open length of chain. Time drops to a crawl and the camera orbits all the way around her, descending, holding on each piece of jewelry in turn before following the bag to the ground. 24 seconds, one continuous take.

ACTIVE REFERENCES
@image4 — woman, mid-20s, slim, light-brown hair pulled back in a low sleek ponytail, defined brows, warm brown eyes, matte terracotta lip, rust-orange ribbed sleeveless mock-neck top, light-wash high-waist straight jeans, white low-profile sneakers. 100% matches the reference.
@image3 — a loose open length of fine gold box-link chain, exactly as shown in the reference: unfastened and laid out free in a long open S-curve, one end tipped with a small gold lobster clasp, the other end tipped with an oval-link extender chain and a flat teardrop tag, and a pinwheel-swirl pendant of six curved gold petals paved with small clear stones around one larger round central stone strung at the lower middle of the strand. Its shape, proportions and open unfastened form 100% match the reference; in this shot it is airborne rather than lying flat.
@image2 — gold earring: chunky high-polish twisted-rope knot ring linked through a smooth thick gold teardrop loop, worn on her LEFT earlobe with a plain gold post visible behind the lobe. 100% matches the reference.
@image1 — gold bracelet: doubled fine curb chain, lobster clasp, short extender chain with a flat oval tag, and a small filigree openwork gold ball charm hanging from the front, worn fastened on her LEFT wrist. 100% matches the reference.
@image5 — blush-pink kraft paper shopping bag, natural cream herringbone cotton rope handles, deep-green satin ribbon tied in a bow at the handles, printed in deep green on the front: a four-leaf clover mark drawn as four line-work hearts, then the word JESSLI in tall serif capitals, and beneath it the word ACESSÓRIOS in small widely-spaced capitals; a scatter of the same green clover marks printed on the side panel. 100% matches the reference.

LOCATION MAP
Foreground: pale grey-and-white patterned cobblestone paving. Midground: the woman on the centre line of a wide open plaza walkway, trimmed low hedges and green lawn on both sides, open paving all around her so the camera has a clear 360-degree path at every radius. Background: a long low pale stone building with small windows on one side, open sky and distant trees on the other, all out of focus. Sun is high, coming from over her left shoulder when she faces the camera at the start.

FIRST FRAME / BLOCKING
Camera 8 cm off the paving, lens tilted slightly up, filling the frame with her white sneakers already mid-stride 1.5 metres away, cobblestone texture sharp in the near foreground, her legs and the plaza receding into soft depth above. She is already walking at 4 km/h from frame one. Her left hand carries the pink bag. The man enters later from camera-right at the frame edge, shoulders only, never fully seen.

FORMAT MODE
One single continuous take from 0.0s to 24.0s. The camera never cuts and never leaves her; framing changes only by physically flying through space around her. Beats land on the stated seconds.

OPTICS
0.0s to 2.5s — 84° ultra-wide at ground level, cobblestones stretched large in the near foreground.
2.5s to 4.5s — 47° neutral, full figure.
4.5s to 8.0s — 47° easing to 12° tele-macro, the floating open chain filling the frame.
8.0s to 11.5s — 12° tele-macro on the earring.
11.5s to 15.0s — 12° tele-macro on the bracelet.
15.0s to 18.5s — 12° tele-macro on her opening hand and the bag handles leaving her fingers.
18.5s to 24.0s — 47° following the falling bag, closing to 12° macro on the printed logo.
Rectilinear glass, prime-lens character, clean natural motion-blur on every moving element. FOV holds steady inside each hold and eases smoothly during each travel, no drift mid-segment.

CAMERA
A robotic arm on a circular track: mechanically smooth, weighted, no handheld tremor, every move eased in and out, always flying, never parking. After the impact it makes one single continuous clockwise orbit around her as seen from above, starting directly in front of her and coming all the way back around, while descending the whole time from chest height to the paving. Orbit angle by beat, measured clockwise from directly in front of her: 0° at 4.5s, 90° at her left side by 8.0s, 160° behind her left shoulder by 11.5s, 230° behind her by 15.0s, 300° at her right side by 18.5s, 360° back to the front and at ground level by 24.0s. Orbit radius breathes between 2.2 metres while travelling and 0.5 metres while holding on a piece, so every arrival is a physical push-in and every departure a physical pull-out. Her body stays in frame through every travel, so her collarbone, neck, jaw, ear, ponytail, shoulder, upper arm, elbow, forearm and hand all cross frame in sharp continuous view between the holds. Wide tonal latitude, gentle highlight roll-off on the gold, warm neutral colour science.

ACTION
0.0s to 2.5s — Camera at ankle height, retreating at 4 km/h; her sneakers and jean hems stride toward the lens, her shadow sweeping across the cobblestones, the pink bag swinging at the top of frame.
2.5s to 4.5s — Camera rises to chest height, pulls back and begins drifting camera-left to a full-figure frame. She walks straight ahead, jaw set, eyes fixed past the camera, arms swinging naturally.
4.5s — A man's shoulder enters from camera-right and clips her right shoulder. Her torso rotates 20 degrees, her ponytail swings, her left hand opens. At the same instant the lobster clasp at the nape of her neck springs open, one end of the chain slides forward around her neck and the whole strand lifts clear of her skin. Time drops to 10% speed and holds there until 18.5s.
4.5s to 8.0s — BEAT 1, THE FLOATING CHAIN. The freed strand rises off her body and hangs in the air a full arm's length in front of her chest, with clear open air visible between the chain and her neck and shoulders. It holds the same long open S-curve as the reference, tilted diagonally across the frame and rotating slowly in three dimensions, the lobster-clasp end trailing at one side, the extender chain and teardrop tag trailing at the other, the pinwheel pendant hanging from the lower middle of the strand and turning on its own axis. The arm orbits from 0° to 90° around her while pushing in to macro, so the reflection of the open sky rolls slowly along the strand as the viewing angle changes, each link reading as a small warm top surface and a darker underside, the pendant's curved petals passing through soft broad reflection and back into shade as they turn.
8.0s to 11.5s — BEAT 2, EARRING. Without stopping, the arm pulls out, keeps orbiting to 160° behind her left shoulder and rises, passing in sharp view over her shoulder, the line of her neck and her jaw, then pushes in to hold macro on her left earlobe: the twisted gold knot swinging a few millimetres inside the smooth teardrop loop, the rope twist reading as alternating bands of lit and shaded metal, the plain gold post sitting warm and matte in the shade behind the lobe, her ponytail drifting slowly through the background of the frame.
11.5s to 15.0s — BEAT 3, BRACELET. Without stopping, the arm pulls out, keeps orbiting to 230° directly behind her and tips down, gliding along her shoulder, upper arm, inner elbow and forearm in sharp continuous view, then pushes in to hold macro on her left wrist: the doubled curb chain lifted off her skin by the motion, the small filigree ball charm swinging and turning so the open cut-outs show shadow through the metal, the flat oval tag rotating over and returning a soft wide reflection of the pale paving before turning back to shade.
15.0s to 18.5s — BEAT 4, THE RELEASE. Without stopping, the arm orbits on to 300° at her right side and slides ten centimetres down to her hand, holding macro as her fingers open one by one and the cream rope handles slide off her fingertips, the ribbon bow lifting as the bag starts to leave her.
18.5s to 24.0s — BEAT 5, THE BAG. Speed ramps back to real time. The arm pulls out and dives with the bag, completing the orbit to 360° and dropping to the paving; the bag tumbles once, lands flat on its base on the cobblestones with a small bounce, ribbon settling. The arm keeps arcing low around it and pushes in to fill the frame with the printed front of the bag, the clover mark and the words JESSLI and ACESSÓRIOS sharp and centred as the take ends.

PERFORMANCE
Pore-level skin realism, fine facial down catching the sun, capillary flush on her cheeks and shoulders, sharp bright catch-lights in living eyes. She never looks at the camera. Before the impact: chin level, lips closed, a single unhurried blink, eyes tracking a point far past the lens. At the impact: eyebrows lift a fraction, lips part, shoulders drop back a beat late, the left hand opening from the fingers outward. Through the slow-motion beats she keeps drifting forward and breathing, eyes still forward past the lens.

PHYSICS
The freed strand behaves like a weighted ribbon cut loose: it ripples along its whole length, each free end trailing and whipping a beat behind the middle, the heavier pendant leading the curve while the light clasp end lags furthest, and the whole strand hangs suspended in open air with a clear gap between it and her body. The earring pivots on its post with real inertia. The bracelet chain lags her wrist, the ball charm swinging on its own small arc. The paper bag has light mass and a low centre of gravity: it rotates slowly around its own axis in the air, the cotton handles arcing above it, and lands with a soft flex of the paper. Every object casts a sharp contact shadow on the stones. Fine dust motes hang in the sunlit air along the whole orbit path.

MATERIAL RENDERING
The gold is real polished metal in open daylight: it renders by reflecting its surroundings — the blue of the sky on the upward faces, the warm bounce of the pale paving on the downward faces — as broad soft highlights that roll slowly across each curved surface as the piece turns, with plenty of shaded matte gold in between. Micro-scratches and fine polish grain stay visible on the larger surfaces. The clear stones read as small faceted glass with quiet internal refraction, sitting close in brightness to the metal around them.

LIGHTING
High midday sun, 5600K, fixed in the sky for the entire take, so as the camera orbits the same sun reads as backlight, then side light, then front light on her in turn, and her cast shadow stays pointing in one constant direction on the paving. Exposure is set for her skin, so highlights on the gold stay inside range and hold their colour. Soft bounce off the pale cobblestones fills her face and arms from below at about one third the key.

WARDROBE
Rust-orange fine-ribbed sleeveless mock-neck top, dry and smoothly fitted; light-wash rigid denim jeans with visible weave; clean white leather sneakers. Bare arms and bare neck, so the freed chain reads clearly against open skin and open air.

AUDIO
Ambient outdoor air and distant footsteps; a soft shoulder impact; a thin metallic chain shimmer that rings out and fades; a light paper thud as the bag lands.

STYLE
Photoreal live-action commercial, natural daylight, high micro-detail on metal and skin, clean modern jewellery-brand look, restrained naturalistic contrast, fine natural grain, 8K detail intent.

OUTPUT SETTINGS
Vertical 9:16, 24 seconds total. Real time from 0.0s to 4.5s, 10% speed from 4.5s to 18.5s, real time from 18.5s to 24.0s.

POSITIVE LOCKS
The chain keeps the open unfastened S-curve shape of its reference for the whole take, with both free ends visible: the lobster clasp on one tip, the extender chain and teardrop tag on the other.
From 4.5s onward the chain is fully off her body, hanging alone in open air with a visible gap of clear air between it and her neck, chest and shoulders. Her neck stays bare from 4.5s to the end of the take.
Every highlight on the jewelry comes from the real environment reflecting in polished metal: broad, soft, slowly rolling, held inside exposure range, with matte shaded gold across most of each piece at any moment, and gold brightness sitting in the same range as the sunlit paving around it.
The bracelet stays fastened around her left wrist for the whole take.
One single unbroken take: the image stays fully opaque, sharp and continuously visible in every frame from 0.0s to 24.0s, and every change of framing happens as a physical camera flight through space with her body in frame the whole way.
The camera keeps orbiting for the entire second half of the take, never holding a static position, completing one full clockwise circle around her while descending from chest height to the paving.
Each beat holds its subject for its full stated duration: chain 4.5s to 8.0s, earring 8.0s to 11.5s, bracelet 11.5s to 15.0s, hand and handles 15.0s to 18.5s, bag 18.5s to 24.0s.
The printed bag artwork stays identical and correctly spelled in every frame it appears: the four-leaf clover of line-drawn hearts, JESSLI in tall serif capitals, ACESSÓRIOS in small spaced capitals beneath, all deep green on blush-pink paper, sharp and legible in the final macro.
The pendant, link pattern, earring form and bracelet charm each keep the exact shape of their reference in every frame.
Her gaze stays forward and past the lens throughout.
Sun position, shadow direction and 5600K white balance hold from first frame to last.
