Eight MARLOW products mounted around a white ferris wheel on a green polo field

Hero frame: MARLOW Ferris Wheel

The process

The entire film depends on a single master still. Reusing it fixes the wheel geometry, product identities, positions, camera distance, light, grass, and sky across both generated clips.

Riverflow workflow

One hero frame, one continuous illusion

The wheel must read as a real four-metre retail installation: a mathematically complete circle, exactly eight spokes, exactly eight mounting points, and physically attached products.

MARLOW clothing and accessories mounted on a white ferris wheel in a polo field

MARLOW Ferris Wheel on a Polo Field

Eight clothing and accessory products sit on the front rim of a complete white timber ferris wheel in hard midday light.

Use when: Use Riverflow 2.5 and output a 9:16 vertical 4K hero frame.

Original prompt
USE CASE: high-end fashion brand campaign photograph (advertising hero frame) STYLE: cross between Ralph Lauren polo-field campaign photography and a large-format architectural still life — a real built retail installation photographed outdoors, editorial, expensive, high contrast, absolutely not a 3D render and not an illustration SCENE: exterior, a wide flat immaculately mown polo field of bright saturated green grass, a dense dark treeline of full summer trees along a low horizon, a deep clear cloudless blue sky filling the upper half of the frame. Midsummer, high noon, brilliant hard natural sunlight from high and slightly camera-left, enormous quantity of light, crisp defined shadows, the structure casting one clean sharp shadow across the grass. Shot on a Phase One XF IQ4 150MP medium format body with a Schneider 110mm LS f/2.8 lens, tripod at axle height, dead straight on, verticals perfectly plumb, real lens compression, no wide-angle distortion. Structure and products tack sharp, treeline and far field in soft natural depth of field. Nothing on the ground but grass, the two feet of the support, and the shadow. SUBJECT — THE WHEEL, GEOMETRY IS THE PRIORITY: one real Ferris-wheel display structure in matte lacquered optic-white timber, centred in frame. The wheel is a MATHEMATICALLY PERFECT CIRCLE: its bounding box is an exact square, its width and its height are identical, it is never an oval, never an ellipse, never wider than it is tall, never flattened or squashed at the top or the bottom. The outer rim is one single closed continuous timber ring of exactly constant thickness for the entire 360 degrees, with no gap, no break, no missing segment, no straight or flat section anywhere — the complete lower arc at the bottom of the circle is fully drawn and fully visible. SUBJECT — THE SUPPORT, DESIGNED SO IT NEVER BREAKS THE CIRCLE: the whole wheel is raised clear of the ground. A white timber A-frame stands BEHIND the wheel, its two splayed legs rising from the grass and meeting at the central axle at the back of the hub, with one horizontal cross brace low between the legs. The legs pass behind the rim and never cross in front of it, never interrupt it and never hide any part of it. There is a clear visible gap of open grass between the very bottom of the rim and the ground, so the entire circle reads complete and unobstructed against the field. SUBJECT — THE SPOKES: exactly EIGHT identical thin white spokes radiate from a small central hub at exactly 45-degree intervals, like a complete symmetrical eight-spoke bicycle wheel — one to twelve o'clock, one to one-thirty, one to three, one to four-thirty, one to six, one to seven-thirty, one to nine, one to ten-thirty. The spoke pointing down and to the right toward five o'clock is present. Every spoke is the same thickness and runs the full distance from hub to rim, meeting the rim cleanly. No thick central cross, no doubled spokes, no extra bracing bars, no inner ring. The spokes are bare structure: nothing is attached to them and nothing hangs from them. DETAILS — MOUNTING, THE OTHER PRIORITY: there are exactly eight mounting points, one at each 45-degree position, and every single one is on the FRONT FACE of the rim — the flat face of the timber ring that points straight at the camera. Small steel hooks and small white shelf brackets are bolted to that front face and project forward toward the lens. Every product therefore hangs from or rests on the rim itself, sitting IN FRONT OF the white ring, closest to the camera, visibly overlapping and partly covering the rim behind it, each casting its own small drop shadow onto the white timber. Every product is physically touching its hook or its shelf. No product hangs from empty air, no product floats, no product is detached from the wheel, no product sits below the wheel, outside the circle, or in front of the A-frame legs. Every hanging garment drapes downward and inward from its hook under its own weight and stays within the circle. DETAILS — THE EIGHT PRODUCTS, each attached at its own rim position: at twelve o'clock, against pure blue sky, a British racing green linen camp-collar overshirt on a pale wooden hanger hooked over the front of the rim, the boldest colour in the picture; at ten-thirty, a small tobacco-tan leather washbag resting on a white bracket shelf; at one-thirty, a white cotton five-panel cap resting on a white bracket shelf; at nine o'clock, a cream knitted polo shirt on a pale wooden hanger hooked to the front of the rim; at three o'clock, a tobacco-tan canvas-and-leather holdall hanging by its top handle from a hook on the front of the rim; at seven-thirty, against the green grass, a navy pique polo shirt on a pale wooden hanger hooked to the front of the rim, its hanger clearly gripping the rim; at four-thirty, against the grass, a navy canvas backpack hanging by its top loop from a hook on the front of the rim, the loop clearly closed around the hook; at six o'clock, a pair of white leather sneakers with navy heel tabs resting side by side on a white bracket shelf bolted to the front of the lowest point of the rim — the sneakers sit ON the bottom of the wheel itself, never on the ground and never on the support. At the centre, a modest white circular hub disc about one quarter of the wheel's diameter bearing one single graphic: two crossed rowing oars in flat solid navy, each with a long slim shaft and a distinct wide flat blade, crossing in an X — recognisably oars, not a plain X and not an asterisk. Each product carries one tiny navy embroidered crossed-oars emblem, white on the navy pieces. DETAILS — SCALE: the wheel is about four metres in diameter. The three garments are the same real size as one another, the cap and washbag are small accessories, the sneakers are one ordinary pair of shoes, the backpack and holdall are ordinary medium bags. Everything is sized as though a person could lift it off the wheel. PALETTE: #16264F · #1B5E3A · #FAFAF7 · #8A5A2B · #EFE7D6 · #2E6FD9 · #3E8A2E IMPERFECTIONS: real fabric weight with soft creases at sleeves and hems, faint brush and grain texture in the lacquered white timber, small visible steel hooks and bolt heads, contact shadows wherever an object touches the structure, mown grass texture and mower stripes, fine organic 35mm film grain, subtle halation on the brightest whites, gentle highlight roll-off, professional commercial LUT — deep saturated blue sky, rich green grass, clean neutral whites that never clip, open shadows. CONSTRAINTS: no text of any kind, no brand name, no wordmark, no letters, no numbers, no labels, no signage, no watermark; no people, no horses, no animals, no buildings, no flags, no banners; no furniture, plants or props on the ground; the wheel is never oval, elliptical, flattened or open; never fewer or more than eight spokes; nothing attached to the spokes; no product floating, detached, hanging from air, sitting on the ground, or placed below or outside the rim; no extra products, no duplicated products, no extra shelves; no metal, plastic, toy-like, CGI, render or illustrated look; no AI smoothing, no HDR, no lens flare. OUTPUT: Output in exactly 1080px x 1920px (9:16 portrait vertical format). Negative prompt: oval wheel, elliptical rim, egg-shaped wheel, flattened top, squashed circle, wider than tall, broken rim, open rim, gap in rim, missing lower arc, straight flat rim segment, rim interrupted by the support, support legs crossing in front of the rim, missing spoke, seven spokes, nine spokes, uneven spoke spacing, thick central cross, doubled spokes, inner ring, products hanging from spokes, products hanging from nothing, floating products, detached products, products below the wheel, products outside the circle, products resting on the ground, products on the support frame, sneakers on the grass, pasted-on cutouts, no contact shadow, mismatched product scale, duplicate products, extra shelves, text, lettering, wordmark, numbers, labels, signage, watermark, people, horses, animals, buildings, flags, banners, ground props, potted plants, 3D render, CGI, toy-like, plastic sheen, illustration, over-rendered, AI-smoothed, oversaturated, HDR, lens flare, distorted geometry, studio backdrop, stock photo feel

Example prompt

Start frame: the hero frame. Reference: the hero frame only. Style/Camera: Photorealistic premium fashion product film. Dynamic high-end commercial cinematography. One single continuous physical shot around a real Ferris wheel. @Image 1 is the exact initial physical scene reference. Preserve the Ferris-wheel geometry, product identities, product placement, camera perspective, outdoor environment, daylight, shadows and overall composition. Generate ONE SINGLE CONTINUOUS SHOT lasting exactly 20 seconds. CRITICAL GLOBAL ACTION RULE: THE ACTION STARTS AT EXACTLY 0.00 SECONDS. There must be ZERO waiting time at the beginning. At the exact first frame, the Ferris wheel is ALREADY moving at its normal, steady operating speed AND the first camera crash zoom toward Product 1 begins IMMEDIATELY. Do NOT hold the initial wide shot. Do NOT spend the first seconds establishing the scene. Do NOT wait 1 second, 2 seconds or 3 seconds before the first zoom. The first camera movement MUST be visibly underway from the very beginning of the video. At 0.00s: THE FERRIS WHEEL IS MOVING. THE CAMERA IS MOVING. THE FIRST CRASH ZOOM IS STARTING. The viewer must immediately perceive both motions. The timing and duration of all subsequent product transitions should remain compact and consistent. CRITICAL FERRIS-WHEEL CONTINUITY: The Ferris wheel is NOT an animated background. It is the continuously moving physical mechanism that drives the entire shot. The Ferris wheel rotates continuously at a NORMAL, STEADY, BELIEVABLE operating speed from 0.00s to 20.00s. It NEVER stops. It NEVER pauses for a zoom. It NEVER slows down because the camera gets close. It NEVER accelerates artificially. It NEVER reverses. It NEVER resets. The physical rotation must continue even when the Ferris wheel is completely outside the camera frame. This is extremely important. When the camera crash zooms into a product, the Ferris wheel does NOT freeze just because it is no longer visible. The wheel continues physically rotating behind the macro framing. When the camera zooms back OUT, the viewer must be able to SEE THE CONSEQUENCE of that continued rotation. The wheel must have advanced to a new physical rotational position. The zoom-out therefore reveals a Ferris wheel that has continued rotating, NOT the same Ferris wheel position seen before the zoom-in. The wheel's physical history must never reset. The products must also continue evolving physically during the entire zoom. CAMERA STRUCTURE: The video contains SIX independent closed crash-zoom cycles. Every cycle MUST follow: WIDE / CURRENT WIDE STATE, then CRASH ZOOM IN, then MACRO, then CRASH ZOOM OUT, then CURRENT WIDE STATE, then NEXT PRODUCT. The camera MUST return to the wide Ferris-wheel viewing distance after EVERY product. NEVER move directly from one product to another. NEVER perform macro-to-macro movement. NEVER travel laterally between products while close. The wide composition is mandatory between every product. IMPORTANT: The CAMERA returns to the wide viewing distance. The PHYSICAL FERRIS WHEEL DOES NOT return to its previous position. Every new wide shot is the CURRENT physical state of the continuously rotating Ferris wheel. PRODUCT ORDER: 1. GREEN SHIRT 2. WHITE CAP 3. BROWN DUFFEL BAG 4. NAVY-BLUE BACKPACK 5. CREAM / OFF-WHITE POLO SHIRT 6. WHITE SNEAKERS These six products are the ONLY camera targets. Do not target any other product. Scene Flow: [0.00-3.50s] PRODUCT 1 — GREEN SHIRT START IMMEDIATELY AT 0.00s. At the exact first frame, the Ferris wheel is already rotating at normal steady speed. At the exact same moment, the camera begins the aggressive crash zoom toward the GREEN SHIRT. There must be no static opening. There must be no establishing hold. The first visible camera movement begins at 0.00s. ENTRY: 0.00s onward: aggressively crash zoom directly toward the GREEN SHIRT. The green shirt is the ONLY camera target. The camera physically approaches the existing shirt. The shirt does NOT move toward the camera. While the camera approaches, the Ferris wheel continues rotating normally. The viewer should still perceive subtle motion of the wheel structure, support geometry and neighboring products during the approach. The Ferris wheel must feel mechanically alive rather than frozen. MACRO: Reach a very tight macro view of the green shirt. Show realistic textile weave, seams, collar, buttons, folds and logo. Keep the macro brief. CRITICAL PHYSICAL CONTINUITY DURING MACRO: Even though the Ferris wheel is no longer visible in the macro framing, IT CONTINUES ROTATING PHYSICALLY. Do not freeze the product's physical state. The green shirt remains attached to its support while the support continues traveling along the Ferris wheel's circular path. Gravity continues acting vertically downward. The shirt responds naturally to the wheel's movement with subtle inertia. EXIT: Crash zoom OUT directly away from the SAME green shirt. As the camera retreats, progressively reveal the Ferris wheel again. The viewer MUST visibly perceive that the wheel has advanced from the rotational position seen before the zoom-in. The support geometry and neighboring products must reveal the continued rotation. Do NOT reconstruct the initial wheel position. Do NOT reset the wheel. RETURN TO CURRENT WIDE: Finish this cycle at the current wide viewing distance. The Ferris wheel is now in a physically ADVANCED rotational position. [3.50-6.50s] PRODUCT 2 — WHITE CAP Begin this cycle from the CURRENT WIDE physical state. The Ferris wheel is already rotating normally. Do not reset it to the original composition. CRASH ZOOM IN directly toward the SMALL WHITE CAP. The white cap is the ONLY target. The camera physically approaches the existing cap. The wheel continues rotating continuously underneath the camera movement. During the zoom-in, the changing position of the wheel must remain physically coherent. MACRO: Reach an extreme close-up of the existing white cap. Show realistic white fabric, stitching, curved brim and embroidered crossed-oars logo. Keep the macro brief. During this macro, the Ferris wheel continues rotating off-screen. The cap remains attached to its original support. Gravity continues acting normally. The cap has subtle natural inertia. The physical wheel DOES NOT pause. EXIT: Crash zoom OUT directly away from the SAME white cap. As the camera retreats, the Ferris wheel progressively re-enters the frame. The wheel MUST visibly be further along its rotation than when the zoom-in started. The spectator should be able to feel: THE WHEEL KEPT MOVING WHILE WE WERE CLOSE TO THE PRODUCT. Return completely to the CURRENT WIDE state. Do not reset the wheel. [6.50-9.50s] PRODUCT 3 — BROWN DUFFEL BAG Begin from the CURRENT WIDE state. The wheel is already rotating at the same normal speed. CRASH ZOOM IN directly toward the LARGE BROWN DUFFEL BAG. The brown duffel is the ONLY target. No lateral transition from the previous product. The camera physically approaches the existing bag. The wheel continues rotating normally throughout the zoom. MACRO: Extreme close-up of the brown duffel. Show realistic material texture, handles, seams, stitching, hardware and logo. The bag has subtle gravity-driven pendulum movement. Do not freeze it. Do not exaggerate the movement. While the camera is close, the wheel continues rotating physically outside the frame. EXIT: Crash zoom OUT directly from the SAME duffel. As the camera pulls away, reveal the wheel in its NEW, ADVANCED rotational position. The viewer must see that the wheel has continued moving during the macro. Return completely to the CURRENT WIDE state. Never restore the previous wheel position. [9.50-12.50s] PRODUCT 4 — NAVY-BLUE BACKPACK Begin from the CURRENT WIDE state. The Ferris wheel is still rotating at normal steady speed. CRASH ZOOM IN directly toward the NAVY-BLUE BACKPACK. The backpack is the ONLY target. The camera physically approaches the existing backpack. The Ferris wheel continues moving normally during the entire approach. MACRO: Reach an extreme close-up. Show realistic woven navy canvas, seams, zipper, zipper pull, straps, top handle and embroidered crossed-oars logo. The backpack remains attached to its original support. Subtle natural inertia only. During the macro, the Ferris wheel continues rotating continuously outside the frame. The physical state is NOT frozen. EXIT: Crash zoom OUT directly away from the SAME backpack. Reveal the Ferris wheel progressively. The wheel must now be visibly further around its circular path. The viewer must understand that the wheel has continued rotating throughout the macro. Return completely to the CURRENT WIDE state. [12.50-15.50s] PRODUCT 5 — CREAM / OFF-WHITE POLO SHIRT Begin from the CURRENT WIDE state. The Ferris wheel continues rotating normally. CRASH ZOOM IN directly toward the CREAM / OFF-WHITE POLO SHIRT. The cream polo is the ONLY target. Do not target the navy polo. Physically approach the existing polo. The wheel continues rotating throughout the zoom. MACRO: Extreme close-up showing realistic woven fabric, collar, buttons, seams, folds and embroidered logo. The polo remains attached to its original hanger. Allow subtle natural fabric inertia. The wheel continues rotating physically even though it is outside the macro frame. EXIT: Crash zoom OUT directly away from the SAME polo. Reveal the wheel again. The wheel must be in a new rotational position caused by its uninterrupted movement during the macro. Return completely to CURRENT WIDE. [15.50-18.50s] PRODUCT 6 — WHITE SNEAKERS Begin from the CURRENT WIDE state. The Ferris wheel is still moving at normal steady speed. CRASH ZOOM IN directly toward the WHITE SNEAKERS. The sneakers are the ONLY target. Physically approach the existing sneakers. The wheel continues rotating continuously. MACRO: Extreme close-up showing realistic material texture, stitching, laces, sole construction and product details. The sneakers remain attached to their original support. Their greater rigidity means less visible movement than the lightweight garments. The Ferris wheel continues rotating physically during the macro. EXIT: Crash zoom OUT directly away from the SAME sneakers. As the camera retreats, reveal the wheel in its latest, physically advanced rotational position. The viewer must be able to see that the wheel has continued rotating while the camera was close. Return completely to the CURRENT WIDE state. [18.50-20.00s] FINAL WIDE Remain in the CURRENT wide composition. The Ferris wheel continues rotating at its SAME NORMAL, STEADY SPEED. Do not stop. Do not slow down. Do not reset. Do not start another zoom. The final frame must show the natural continuation of the wheel's physical rotation. PHYSICS — ABSOLUTE PRIORITY: The Ferris wheel rotates continuously around its central axis. Its angular velocity remains approximately constant. The wheel has real mechanical mass. The supports travel along the circular path. GRAVITY ALWAYS POINTS VERTICALLY DOWNWARD IN WORLD SPACE. Products do NOT simply rotate rigidly together with the Ferris wheel. Each product remains attached to its support while responding naturally to gravity, inertia and circular acceleration. The attachment point moves with the wheel. The product's mass resists sudden changes in orientation. This produces subtle natural lag and pendulum behavior. LIGHTWEIGHT PRODUCTS: Green shirt and cream polo can show subtle fabric movement, slight inertial lag and small natural settling motions. MEDIUM-WEIGHT PRODUCTS: The cap and backpack can show restrained inertial movement. HEAVIER / RIGID PRODUCTS: The sneakers remain comparatively stable. The brown duffel has subtle pendulum behavior due to its hanging mass. Do not make all products move identically. Do not make all products completely static. Do not make all products swing dramatically. Every movement must be caused by gravity, inertia, mass and the continuous movement of the Ferris wheel. CRITICAL: WHEN THE CAMERA ZOOMS IN, THE WHEEL KEEPS MOVING. WHEN THE CAMERA IS IN MACRO, THE WHEEL KEEPS MOVING OFF-SCREEN. WHEN THE CAMERA ZOOMS OUT, THE WHEEL'S CONTINUED ROTATION MUST BE VISIBLE AGAIN. The zoom-out must act as visual proof that the wheel never stopped. The wheel's new position after each zoom-out must be physically consistent with the amount of time that has passed. Never restore the wheel to its previous orientation. Never freeze the world during a macro. Never reset the products to their previous positions. CAMERA MOVEMENT: All crash zoom-ins are aggressive, fast and precise. The camera travels directly toward the selected product. The product never travels toward the camera. The apparent enlargement comes ONLY from camera movement. All crash zoom-outs directly reverse the camera distance. The camera returns to the wide viewing distance. No lateral product-to-product travel. No orbiting around the Ferris wheel. No camera teleportation. AUDIO: ABSOLUTELY NO MUSIC. NO MUSICAL SCORE. NO MELODY. NO BACKGROUND MUSIC. NO MUSICAL BED. Use ONLY natural ambience and sound effects. Natural outdoor ambience continues throughout the entire video. Continuous subtle Ferris-wheel mechanical ambience: bearings, low mechanical friction, faint structural movement and subtle creaks synchronized with the wheel's rotation. The mechanical sound must CONTINUE DURING EVERY ZOOM. It must NOT disappear when the camera enters macro. The continuous mechanical ambience should subtly remind the viewer that the Ferris wheel is still physically rotating even when it is outside the frame. Each crash zoom IN has a short, restrained cinematic air/whoosh synchronized precisely with camera acceleration. Each crash zoom OUT has a short, restrained reverse/air whoosh synchronized precisely with camera retreat. These are SFX ONLY. They must never sound musical. No dialogue. No narration. No subtitles. LIGHTING: Preserve the natural daylight, blue sky, grass, tree line, white Ferris-wheel structure and realistic shadows from @Image 1. Lighting remains physically consistent during the entire continuous shot. Macro views retain realistic product lighting and material response. Do not transform macro views into studio product photography. CONTINUITY: The physical world never resets. The Ferris wheel has one continuous rotational history from 0.00s to 20.00s. Every zoom-in occurs on the wheel's CURRENT state. Every macro occurs while the wheel continues moving. Every zoom-out reveals the wheel's NEW state. Every next zoom begins from that NEW current state. This is one continuous physical machine, one continuous rotation and one continuous camera journey. ABSOLUTE EXCLUSIONS: No initial waiting period. No static opening. No delayed first zoom. No stopping the Ferris wheel. No slowing the Ferris wheel during zooms. No resetting the Ferris wheel. No reversing the Ferris wheel. No freezing the Ferris wheel during macro. No freezing the products during macro. No direct product-to-product transition. No macro-to-macro transition. No incomplete return to wide. No camera teleportation. No product teleportation. No product duplication. No product swapping. No product disappearance. No giant products. No digital scaling. No product flying toward camera. No floating products. No detached products. No independent product spinning. No weightless physics. No exaggerated swinging. No artificial wind. No background replacement. No studio background. No focus hunting. No excessive camera shake. No deformation. No identity changes. No color changes. No logo changes. No material changes. No proportion changes. FINAL PRIORITIES, IN ORDER: 1. ACTION STARTS AT EXACTLY 0.00s. 2. FIRST CRASH ZOOM BEGINS IMMEDIATELY AT 0.00s. 3. FERRIS WHEEL ROTATES CONTINUOUSLY AT NORMAL STEADY SPEED FROM 0.00s TO 20.00s. 4. THE WHEEL CONTINUES MOVING DURING EVERY ZOOM-IN. 5. THE WHEEL CONTINUES MOVING DURING EVERY MACRO. 6. THE WHEEL CONTINUES MOVING DURING EVERY ZOOM-OUT. 7. EVERY ZOOM-OUT MUST REVEAL A PHYSICALLY ADVANCED WHEEL POSITION. 8. CAMERA ALWAYS RETURNS TO WIDE BEFORE TARGETING THE NEXT PRODUCT. 9. PRODUCTS OBEY GRAVITY, MASS AND NATURAL INERTIA. 10. NO MUSIC — ONLY NATURAL AMBIENCE AND SYNCHRONIZED SFX.

Example prompt

Start frame: the hero frame. Reference: the hero frame only. This is the tail of the film. Style/Camera: Photorealistic premium fashion product film. Use @Image 1 as the exact START FRAME reference. Preserve the exact Ferris-wheel geometry, product identities, product placement, camera position, perspective, outdoor environment, daylight, shadows and composition. Generate ONE SINGLE CONTINUOUS SHOT lasting exactly 5 seconds. The video MUST begin exactly from the visual state shown in @Image 1. At 0.00s the Ferris wheel immediately begins rotating naturally at a NORMAL, STEADY SPEED — neither slow nor fast. The Ferris wheel performs approximately HALF A ROTATION over the full 5-second shot. The rotation must feel like a real Ferris wheel driven by a constant mechanical motor: smooth, continuous and physically believable, with no acceleration bursts, no pauses and no reversal. CAMERA: The camera remains completely fixed throughout the entire 5 seconds. No zoom. No dolly. No pan. No tilt. No orbit. No tracking. No camera shake. The entire movement comes from the physical rotation of the Ferris wheel. FERRIS-WHEEL PHYSICS: The Ferris wheel is a real rigid mechanical structure rotating continuously around its central horizontal axis. The wheel rotates smoothly and consistently throughout the entire shot. The gondolas, hangers and product supports are physically attached to the wheel. CRITICAL GRAVITY RULE: Gravity always points vertically downward in world space. The products must NOT simply rotate rigidly together with the Ferris wheel. Each product remains attached to its support while responding naturally to gravity, inertia and the circular movement of the wheel. The support follows the circular path of the Ferris wheel, while each hanging product naturally resists changes in orientation. Products should therefore maintain a natural gravity-oriented behavior rather than behaving like rigid objects glued to the wheel. The center of mass of each hanging product remains physically believable throughout the rotation. PRODUCT PHYSICS: Lightweight products such as T-shirts, shirts and sweatshirts show slightly more natural inertial movement, subtle fabric response and very small delayed settling as their supports move. Medium-weight products such as caps and backpacks remain comparatively stable but can show restrained natural inertia. Heavier or rigid products such as shoes remain substantially more stable, with minimal visible movement. Hanging bags may exhibit a very subtle pendulum response caused by gravity and the changing direction of acceleration. Do NOT make all products move identically. Do NOT freeze the products. Do NOT make them swing dramatically. Do NOT make them independently rotate. Every movement must be subtle, mass-dependent and caused by gravity, inertia and the continuous circular motion of the Ferris wheel. The products remain attached to their original supports at all times. No product detaches, floats, jumps or changes position independently. ROTATION: [0.00-5.00s] Start exactly from @Image 1. At 0.00s the wheel is already beginning its rotation. Maintain a smooth, constant, normal operating speed throughout the shot. The wheel progressively advances through approximately 180 degrees of rotation by 5.00s. The rotation direction must remain constant throughout the entire shot. No reversal. No stop. No acceleration. No deceleration. As different products travel through the circular path, their physical behavior must continuously respond to gravity and inertia. The relationship between the wheel, supports and products must remain mechanically coherent from the first frame to the last frame. By 5.00s the Ferris wheel has completed approximately HALF A ROTATION relative to the exact starting state in @Image 1. The final state must be the natural physical consequence of the continuous rotation, not a separately reconstructed frame. LIGHTING: Preserve the exact natural daylight, sky, grass, shadows and product illumination from @Image 1. Lighting remains physically consistent while the wheel rotates. No background replacement. No studio transformation. No changes to product colors or materials. AUDIO: No music. Use only subtle natural outdoor ambience and realistic Ferris-wheel mechanical SFX. Continuous low mechanical bearing movement, subtle structural creaks and restrained wheel and mechanism sounds synchronized with the rotation. Very subtle natural wind ambience. No dialogue. No narration. No subtitles. No musical elements. CONTINUITY / EXCLUSIONS: The first frame must match @Image 1 exactly. The Ferris wheel must physically rotate continuously for the entire 5 seconds. Approximately half a rotation over 5 seconds. Normal operating speed: neither very slow nor very fast. Constant direction. Constant believable angular velocity. Gravity remains vertically downward in world space. Products respond naturally according to their mass, rigidity, attachment and inertia. No full rotation beyond approximately 180 degrees. No camera movement. No zoom. No product duplication. No product swapping. No product disappearance. No product deformation. No detached products. No floating products. No weightless behavior. No rigidly glued product rotation. No exaggerated swinging. No artificial wind. No sudden acceleration. No sudden deceleration. No reversal. No teleportation. No change to product identity, proportions, colors, materials or logos.

The CapCut edit

Place Clip A first and Clip B second. Do not add a transition: the hard cut preserves the shared geometry and light. Keep the native audio from both clips so the mechanical ambience carries across the cut. If you add music, place it on a separate track and keep the mechanism audible. Export at 1080p in 9:16.

Before you publish

Rules that protect the illusion

  • Use one approved hero image as the start frame for both clips.
  • The ferris wheel keeps rotating during every zoom-in, macro, and zoom-out; the world never resets.
  • The camera approaches each existing product; products never scale or fly toward the lens.
  • Return fully to the current wide composition before targeting the next product.
  • Gravity stays vertical and product movement varies naturally with fabric weight, rigidity, and attachment.
  • Use ambience and synchronized effects only inside the generation, with no music, narration, or dialogue.

FAQ

Which model should I use for the hero frame?

Use Riverflow 2.5 and generate the still at 9:16 vertical.

Why must both clips use the same start frame?

It keeps the wheel geometry, products, camera, environment, and lighting identical at the edit point, so a hard cut reads as one continuous film.

Why return to wide after every macro?

The wide reveal proves that the wheel continued rotating while it was out of frame and prevents impossible product-to-product transitions.

Should I add a transition in CapCut?

No. Place the clips end to end with a hard cut, retain the native mechanical ambience, and export at 1080p in 9:16.
