Frame 04: Rock Beach - Morning Stretch

Frame 05: Sea of Clouds - Product Alone

Frame 06: Green Meadow - Wind & Linen

Frame 07: Blue Studio - Unboxing
The process
Build the NUBA product reference first, then generate the still-image carousel, and only animate approved frames. The reference sheet is the product source of truth across the campaign.
Riverflow workflow
Product first, then image, then motion
Follow the reference roles in each prompt. The product sheet controls the mattress design; the model reference controls IRIS's identity; and the composition reference controls the named staging and camera choices.
Product
Create the reference sheet
Bring the finished NUBA logo, label design, colors, and packaging text into Riverflow. Use Frame 00 to generate the clean top, side, and three-quarter product sheet, then lock the approved result as the product reference.
Images
Generate the seven campaign stills
Choose Riverflow 2.5, attach the references named by the frame, paste the complete prompt, and generate at the exact output dimensions written in that prompt.
Review
Approve product and model continuity
Check the optic-white mattress, navy NUBA perimeter band, embroidered side labels, model identity, bedding, palette, composition, foreground accent, and crop before moving to motion.
Video
Animate three approved frames
Bring the matching still into Riverflow's video generator, choose Seedance, set it as the start frame, paste the complete motion prompt, and generate the six-second clip.
Eight Riverflow 2.5 prompts
The first prompt creates the reusable product reference sheet. The other seven prompts create the NUBA carousel frames from that approved product source.
The Frame 00 source prompt specifies 3840px x 2160px (16:9 landscape), while the PDF footer describes the output as “4K vertical 16:9.” Both source statements are preserved here rather than silently reconciled.
Visual playbook
The NUBA product sheet and seven-frame carousel
Frame 00 intentionally has no gallery image. Frames 01-07 use the approved campaign images supplied with the guide.
00. Product Reference Sheet - Top / Side / 3D + Specs
A clean one-page specification sheet establishes the exact NUBA mattress design used by every campaign frame.
Use when: Generate this first with Riverflow 2.5 at exactly 3840px x 2160px (16:9 landscape), then lock the approved sheet as the product reference.
Original prompt
USE CASE: brand product specification sheet - a single clean, highly visual one-page product sheet for a premium mattress brand, designed to be used later as the master product reference. STYLE: cross between a Muji-clean Swiss design spec sheet and a modern DTC mattress brand's website product page - generous white space, precise alignment, editorial calm, zero clutter. SCENE: flat studio presentation on a seamless pure white background, soft even large-softbox lighting from top-left, gentle contact shadows under each mattress view, no environment, no props. SUBJECT: the SAME single mattress shown three times across the sheet in three views: (1) LEFT - a perfectly flat top-down orthographic view of the whole mattress, (2) CENTER - a straight-on side elevation showing the mattress profile and its full-length side band, (3) RIGHT - a three-quarter 3D perspective view floating slightly, showing the top surface and two adjacent side panels at once. DETAILS: the mattress is king size, optic white #FFFFFF, smooth flat quilted knit top (fine even quilting, no buttons, no capitonne tufting), straight square edges, medium-high profile. A woven navy blue #0B2E63 perimeter band wraps the ENTIRE mattress on all four sides, carrying the wordmark "NUBA" repeated in white along its full length, plus one centered embroidered white label patch on EACH of the four side panels - in the three-quarter view two of those side labels must be clearly visible. Layout: a thin navy hairline rule across the top of the sheet, the brand wordmark "NUBA" top-left in large navy #0B2E63 letters, a small saffron orange #FF8A1F dot accent next to the wordmark and a thin saffron orange underline beneath the spec column, six specification lines set in a tidy left-aligned column in the lower right, small navy caption labels under each of the three views, thin navy leader lines with dimension arrows on the top view (width and length) and on the side view (height). Everything sharp, product-catalog crisp, all three views fully in focus. TEXT (EXACT): "NUBA" / "THE NUBA MATTRESS" / "TOP VIEW" / "SIDE PROFILE" / "3D VIEW" / "SIZE - 180 x 200 CM" / "HEIGHT - 28 CM" / "COVER - ORGANIC COTTON KNIT" / "CORE - 7-ZONE POCKET SPRING" / "FIRMNESS - MEDIUM" / "WARRANTY - 10 YEARS" TYPOGRAPHY: clean geometric grotesk sans throughout; wordmark in bold uppercase with slightly tightened tracking; spec lines in light uppercase with wide letter-spacing; all text perfectly legible and correctly spelled. PALETTE: #FFFFFF - #0B2E63 - #FF8A1F - #EDE7DA - #0F8FE0 - #3EA845 IMPERFECTIONS: subtle real fabric weave in the knit top, faint natural creases where the quilting pulls, soft realistic contact shadow, believable thread texture on the embroidered labels. CONSTRAINTS: no watermarks, no extra text beyond the exact strings listed, no misspelled or garbled lettering, no people, no bed frame, no pillows, no bedding, no room, no gradient background, no 3D-render plastic look, no AI smoothing. OUTPUT: Output in exactly 3840px x 2160px (16:9 landscape). NEGATIVE garbled text, misspelled words, duplicated letters, illegible labels, extra paragraphs of text, lorem ipsum, watermark, logo of another brand, people, hands, pillows, duvet, bed frame, headboard, room interior, gradient background, colored background, plastic CGI render, over-rendered, halos, fringing, distorted geometry, warped mattress edges, tufted buttons, capitonne, oversaturated, HDR, lens flare, stock photo feel, cluttered layout, tiny unreadable text, more than three mattress views

IRIS lies on the NUBA mattress as it floats alone on a saturated blue sea.
Use when: Use Riverflow 2.5 with the composition and product references named in the prompt, then output exactly 2160px x 3840px (9:16 portrait).
Original prompt
USE CASE: high-end fashion-house advertising campaign image for a mattress brand - the opening frame of a social slideshow. STYLE: cross between a Coperni-style AI brand campaign poster and a Zeiss-sharp aerial editorial photograph - surreal, calm, luxurious, impossibly clean. Follow the FIRST reference image for composition, framing and camera angle. Follow the SECOND reference image for the exact mattress product design. SCENE: open sea, mid-morning, shot straight down from a long telephoto lens very high above the water. Deep saturated blue ocean #0F8FE0 to navy in the troughs, alive with hard sun sparkle and thousands of specular glints, gentle swell texture across the whole frame. Hard high sun from the upper left, crisp short shadows along the mattress edge, extremely high contrast, punchy vivid color. SUBJECT: a single NUBA mattress floating alone on the open sea, perfectly flat, dead centre of frame, occupying the middle two thirds of the image. Lying on her back on it, arms relaxed and open, one knee softly bent, face turned up toward the lens with eyes closed and a calm half-smile: IRIS - a 27-year-old woman, deep dark skin with warm undertone, voluminous shoulder-length curly chestnut-brown hair fanned across the pillow, high cheekbones, full lips, a small beauty mark below her right eye, slim 1.74 m frame. She wears a long ecru off-white silk slip dress with thin straps, the fabric pooling and creasing naturally around her legs. Two plump white pillows above her head, a rumpled white duvet pushed down toward the foot of the mattress. DETAILS: the mattress is optic white #FFFFFF, king size, smooth flat quilted knit top, straight square edges, medium-high profile - identical to the second reference image. A woven navy blue #0B2E63 perimeter band wraps all four sides, carrying the wordmark "NUBA" repeated in white along its length, plus one centered embroidered white label patch visible on EACH of the four side panels - from this top-down angle all four branded sides read clearly around the mattress. In the extreme foreground, drifting into the bottom-right corner and cropped by the frame edge, a huge saffron orange #FF8A1F life ring buoy rendered completely out of focus as a soft glowing orange mass - heavy shallow-depth-of-field blur, the mattress and IRIS tack sharp behind it. Long-lens compression, no wide-angle distortion. The wordmark "NUBA" set in white, centered in the lower area of the frame, clean and generously spaced. TEXT (EXACT): "NUBA" TYPOGRAPHY: clean geometric grotesk sans, lowercase-height proportions, medium weight, wide tracking, pure white, no tagline. PALETTE: #FFFFFF - #0B2E63 - #0F8FE0 - #FF8A1F - #EDE7DA IMPERFECTIONS: real skin texture with visible pores and fine highlights on the shoulders, individual frizzy curls catching the sun, genuine creases and pull-lines in the silk dress and the quilted top, slight lens softness at the extreme corners, fine natural photographic grain, tiny water droplets on the mattress edge nearest the swell. CONSTRAINTS: no watermarks, no extra text of any kind beyond the exact string, no other brand names, no boats, no swimmers, no horizon line, no sky, no land, no railing, no drone visible, no plastic skin, no AI smoothing, no beauty filter, no distorted hands, no second person, no yellow color cast. OUTPUT: Output in exactly 2160px x 3840px (9:16 portrait vertical format). NEGATIVE plastic skin, AI-smoothed skin, over-rendered, doll-like features, waxy skin, airbrushed, beauty filter, face-tune, no skin texture, deformed hands, extra fingers, fused fingers, unnatural pose, stiff body language, duplicate subject, second person, horizon line, sky visible, land, boat, swimmer, drone, railing, tufted buttons, capitonne, warped mattress edges, distorted geometry, illegible label, garbled text, misspelled wordmark, extra text, tagline, watermark, other brand logo, wide-angle distortion, flat all-in-focus rendering, everything sharp foreground, dull desaturated water, muddy blue, yellow color cast, oversaturated HDR, lens flare, stock photo feel

Use when: Use Riverflow 2.5 with the composition, model, and product references named in the prompt, then output exactly 3200px x 4000px (4:5 portrait).
Original prompt
USE CASE: high-end fashion-house advertising campaign image for a mattress brand - frame two of a social slideshow, same world and same product as frame one. STYLE: cross between a surreal Magritte-clean bedding campaign and a Zeiss-sharp long-lens landscape photograph - silent, vast, luxurious, impossibly still. Follow the FIRST reference image for composition, staging and camera angle. Follow the SECOND reference image for the model's exact face and identity. Follow the THIRD reference image for the exact mattress product design. SCENE: an endless mirror-flat salt lake at dawn, a film of shallow water turning the entire ground into a perfect reflecting mirror out to a razor-thin horizon. Above it a deep gradient sky - vivid cyan #0F8FE0 at the horizon climbing to deep saturated blue at the top of the frame, cloudless, extremely high contrast. Low warm dawn sun raking in from the left, long crisp highlights on the water, the whole scene tack sharp and glassy. Shot from very far away on a long telephoto lens, camera almost at water level, slight low angle looking gently up at the mattress, heavy lens compression flattening the distance. SUBJECT: a single NUBA mattress resting directly on the mirror surface - no bed frame, no headboard, no legs, no base - perfectly level, positioned right of centre, its full long side facing camera and its reflection continuing flawlessly beneath it. Sitting on the near edge of the mattress in three-quarter profile facing left, barefoot with one leg tucked under and both hands cradling a plain white ceramic mug lifted toward her lips, eyes half closed, serene: IRIS - a 27-year-old woman, deep dark skin with warm undertone, voluminous shoulder-length curly chestnut-brown hair, high cheekbones, full lips, a small beauty mark below her right eye, slim 1.74 m frame - exactly the same face as the second reference image. She wears a soft ecru terrycloth robe loosely belted. Rumpled white pillows and a white duvet spilling across the mattress toward the far end. DETAILS: the mattress is optic white #FFFFFF, king size, smooth flat quilted knit top, straight square edges, medium-high profile - identical to the third reference image. A woven navy blue #0B2E63 perimeter band wraps all four sides, carrying the wordmark "NUBA" repeated in white along its full length, with one centered embroidered white label patch on each side panel - on this long side facing camera the repeated wordmark and the centered label read clearly and sharply. In the extreme foreground, standing in the shallow mirror water directly in front of the lens at the left of frame and cropped by the frame edge, a large saffron orange #FF8A1F enamel thermos jug rendered completely out of focus - a soft glowing orange mass with its own blurred orange reflection smeared across the water beneath it; the mattress, IRIS and the horizon stay tack sharp behind it. No text anywhere in the image. PALETTE: #FFFFFF - #0B2E63 - #0F8FE0 - #FF8A1F - #EDE7DA IMPERFECTIONS: real skin texture with visible pores and fine dawn highlights along her cheekbone and collarbone, individual frizzy curls catching the low sun, genuine creases and pull-lines in the terrycloth robe and the quilted top, faint salt crust ridges just breaking the water film in the mid distance, tiny ripple rings around the mattress corners, fine natural photographic grain. CONSTRAINTS: no watermarks, no text, no lettering other than the woven "NUBA" on the mattress band, no other brand names, no bed frame, no headboard, no wooden base, no legs, no furniture, no mountains, no buildings, no clouds, no birds, no second person, no plastic skin, no AI smoothing, no beauty filter, no distorted hands, no yellow color cast.

Original prompt
USE CASE: high-end fashion-house advertising campaign image for the mattress brand NUBA - frame three of a social slideshow, same product, same model and same world as the previous frames. STYLE: cross between a sun-bleached editorial bedding campaign and a Zeiss-sharp long-lens aerial photograph - serene, minimal, luxurious. Follow the FIRST reference image for composition, staging and camera angle. Follow the SECOND reference image for the model's exact face and identity. Follow the THIRD reference image for the exact mattress product design. SCENE: a vast field of pale white sand dunes at mid-morning, rippled wind texture combing across the sand, footprints and soft drifts around the bed. Along the top edge of the frame the dunes drop away to a hard band of vivid saturated blue sea #0F8FE0 catching hard sun sparkle. Hard high sun from the upper right, crisp short shadows, very high contrast, punchy vivid color. Shot from far away and high up on a long telephoto lens, steep high-angle looking down at roughly 45 degrees, heavy lens compression. SUBJECT: a single NUBA mattress resting directly on the sand - no bed frame, no headboard, no legs, no base - placed in the lower centre of the frame at a three-quarter angle so two branded sides face camera. Lying face down across it, head turned to the left cheek on the pillow, eyes closed, one arm tucked under the pillow and the other stretched out over the duvet, deeply asleep: IRIS - a 27-year-old woman, deep dark skin with warm undertone, voluminous shoulder-length curly chestnut-brown hair spilling across the white pillow, high cheekbones, full lips, a small beauty mark below her right eye, slim 1.74 m frame - exactly the same face as the second reference image. She wears a simple ecru ribbed cotton tank top. Crisp white bedding: two plump white pillows, a rumpled white duvet pulled up to her lower back, a couple of loose white cushions dropped on the sand beside the mattress. An open paperback lies face down on the duvet. DETAILS: the mattress is optic white #FFFFFF, king size, smooth flat quilted knit top, straight square edges, medium-high profile - identical to the third reference image. A woven navy blue #0B2E63 perimeter band wraps all four sides, carrying the wordmark "NUBA" repeated in white along its full length, with one centered embroidered white label patch on each side panel - the two sides facing camera read clearly and sharply. In the extreme foreground, hanging into the bottom-left corner of the frame and cropped by the edge, a large string mesh net bag full of saffron orange #FF8A1F oranges, rendered completely out of focus as a cluster of soft glowing orange spheres; the mattress, IRIS and the sand stay tack sharp behind it. No text anywhere in the image. PALETTE: #FFFFFF - #0B2E63 - #0F8FE0 - #FF8A1F - #EDE7DA IMPERFECTIONS: real skin texture with visible pores and fine sun highlights on her shoulder blades, individual frizzy curls catching the light, genuine creases and pull-lines in the duvet and the quilted top, a few grains of sand on the mattress edge, wind-combed ripples and small footprints in the sand, fine natural photographic grain. CONSTRAINTS: no watermarks, no text, no lettering other than the woven "NUBA" on the mattress band, no other brand names, no striped or blue-patterned bedding, no bed frame, no headboard, no legs, no furniture, no umbrella, no second person, no plastic skin, no AI smoothing, no beauty filter, no distorted hands, no yellow color cast.

Original prompt
USE CASE: high-end fashion-house advertising campaign image for the mattress brand NUBA - frame four of a social slideshow, same product, same model and same world as the previous frames. STYLE: cross between a Californian coastal fashion campaign and a Zeiss-sharp long-lens documentary photograph - free, wide, luminous. Follow the FIRST reference image for composition, staging and camera angle. Follow the SECOND reference image for the model's exact face and identity. Follow the THIRD reference image for the exact mattress product design. SCENE: a wild beach in late morning - golden wet sand in the mid ground, black volcanic rocks breaking the surf, white foam curling in, and beyond it a huge expanse of vivid saturated blue ocean #0F8FE0 running to a crisp horizon under a clear deep blue sky. Hard high sun from the left, sharp shadows, extremely high contrast, punchy vivid color. Shot from very far back on a long telephoto lens, slightly elevated high angle looking down toward the water, heavy lens compression stacking the rocks and the surf behind the bed. SUBJECT: a single NUBA mattress resting directly on the dry sand in the lower half of the frame - no bed frame, no headboard, no legs, no base - its long branded side facing camera. Standing barefoot on top of the mattress, seen from behind, feet apart and both arms stretched straight up to the sky in a full waking stretch, head tilted back: IRIS - a 27-year-old woman, deep dark skin with warm undertone, voluminous shoulder-length curly chestnut-brown hair, slim 1.74 m frame - exactly the same face and hair as the second reference image, her face turned away in profile so only her jawline and the small beauty mark below her right eye catch the light. She wears an oversized off-white cotton shirt slipping off one shoulder. Crisp white bedding: two white pillows at the far end, a white duvet trailing off the corner onto the sand. DETAILS: the mattress is optic white #FFFFFF, king size, smooth flat quilted knit top, straight square edges, medium-high profile - identical to the third reference image. A woven navy blue #0B2E63 perimeter band wraps all four sides, carrying the wordmark "NUBA" repeated in white along its full length, with one centered embroidered white label patch on each side panel - the long side facing camera reads clearly and sharply. In the extreme foreground, planted upright in the sand at the right of frame and cropped by the frame edge, a tall saffron orange #FF8A1F surfboard rendered completely out of focus as a soft glowing orange column; the mattress, IRIS, the rocks and the ocean stay tack sharp behind it. No text anywhere in the image. PALETTE: #FFFFFF - #0B2E63 - #0F8FE0 - #FF8A1F - #EDE7DA IMPERFECTIONS: real skin texture with visible pores and salt sheen on her back and calves, individual frizzy curls lifted by the sea breeze, genuine creases and pull-lines in the oversized shirt and the quilted top, damp sand clinging to the mattress corner, scattered footprints leading to the bed, fine natural photographic grain.

Original prompt
USE CASE: high-end fashion-house advertising campaign image for the mattress brand NUBA - frame five of a social slideshow, a pure product beat with no model, same product and same world as the other frames. STYLE: cross between a surreal dreamscape poster and a Zeiss-sharp long-lens aerial photograph - weightless, silent, impossible. Follow the FIRST reference image for composition, staging and camera angle. Follow the SECOND reference image for the exact mattress product design. SCENE: high above an endless sea of thick cumulus clouds, the cloud tops rolling away to a crisp horizon. Above them a vivid gradient sky - saturated cyan #0F8FE0 near the horizon climbing to deep intense blue at the top of the frame, a few high wisps of cirrus, extremely high contrast, punchy vivid color, no pastel wash. Hard clean sunlight from the upper left carving bright tops and blue-shadowed valleys into the clouds. Shot from far away on a long telephoto lens, slightly elevated angle looking down onto the floating mattress, heavy lens compression. SUBJECT: a single NUBA mattress floating alone in mid-air just above the cloud tops, dead centre of frame, perfectly level, turned at a three-quarter angle so the long branded side and one short branded end both face camera, a soft cloud curling up around its corners. No person anywhere. Crisp white bedding: a thick white duvet spilling luxuriously over the near edge and trailing down into the cloud, two plump white pillows at the far end, deep soft folds catching the sun. DETAILS: the mattress is optic white #FFFFFF, king size, smooth flat quilted knit top, straight square edges, medium-high profile - identical to the second reference image. A woven navy blue #0B2E63 perimeter band wraps all four sides, carrying the wordmark "NUBA" repeated in white along its full length, with one centered embroidered white label patch on each side panel - both visible sides read clearly and sharply, and this frame is the cleanest read of the branding in the whole campaign. In the extreme foreground, drifting past the lens at the left of frame and cropped by the frame edge, the enormous curved envelope of a saffron orange #FF8A1F hot-air balloon rendered completely out of focus as a huge soft glowing orange arc; the mattress and the cloudscape stay tack sharp behind it. No text anywhere in the image. PALETTE: #FFFFFF - #0B2E63 - #0F8FE0 - #FF8A1F - #EDE7DA IMPERFECTIONS: genuine creases and pull-lines in the duvet and the quilted top, a faint wisp of cloud vapour crossing the mattress edge, slight lens softness at the extreme corners, fine natural photographic grain.

Above it a vivid saturated blue sky #0F8FE0 with crisp white cumulus clouds, extremely high contrast, punchy vivid color. Warm clean sunlight from the left raking across the grass, sharp shadows. Shot from far away on a long telephoto lens, camera low in the grass looking slightly up at the mattress, heavy lens compression stacking the hills behind it. SUBJECT: a single NUBA mattress resting directly on the grass in the lower centre of the frame - no bed frame, no headboard, no legs, no base - its long branded side facing camera, grass blades brushing its edge. Sitting on the near edge with bare feet in the grass, leaning back on both hands, chin lifted and eyes closed to the sun, a soft smile: IRIS - a 27-year-old woman, deep dark skin with warm undertone, voluminous shoulder-length curly chestnut-brown hair lifted by the wind, high cheekbones, full lips, a small beauty mark below her right eye, slim 1.74 m frame - exactly the same face as the second reference image. She wears an ecru linen sleep set. Above and behind her a huge sheer white bed sheet is caught mid-air by the wind, billowing and twisting across the sky in long weightless folds. Crisp white bedding on the mattress: two white pillows, a white duvet half thrown back. DETAILS: the mattress is optic white #FFFFFF, king size, smooth flat quilted knit top, straight square edges, medium-high profile - identical to the third reference image.

SUBJECT: standing right of centre, caught mid-action opening a tall white cardboard box almost as tall as she is, both hands folding the top flaps outward, leaning in and laughing with delight: IRIS - a 27-year-old woman, deep dark skin with warm undertone, voluminous shoulder-length curly chestnut-brown hair, high cheekbones, full lips, a small beauty mark below her right eye, slim 1.74 m frame - exactly the same face as the second reference image. She wears an ecru cotton sweatshirt and matching ecru wide-leg trousers, barefoot. To her right, resting directly on the studio floor with no frame and no base, a single NUBA mattress, its long branded side facing camera, two white pillows squared neatly on top. DETAILS: the mattress is optic white #FFFFFF, king size, smooth flat quilted knit top, straight square edges, medium-high profile - identical to the third reference image. A woven navy blue #0B2E63 perimeter band wraps all four sides, carrying the wordmark "NUBA" repeated in white along its full length, with one centered embroidered white label patch on each side panel - the long side facing camera reads clearly and sharply. The white shipping box carries the wordmark "NUBA" printed large in navy blue #0B2E63 running vertically down its front face, and the small line "nuba.com" beneath it. In the extreme foreground, standing at the left of frame and cropped by the frame edge, a tall saffron orange #FF8A1F floor lamp rendered completely out of focus as a soft glowing orange silhouette; IRIS, the box and the mattress stay tack sharp behind it. TEXT (EXACT): "NUBA" / "nuba.com" TYPOGRAPHY: heavy geometric grotesk sans for the box wordmark, tightly tracked, navy blue; the url in small light uppercase-height letters beneath it; all lettering perfectly legible and correctly spelled. PALETTE: #FFFFFF - #0B2E63 - #0F8FE0 - #FF8A1F - #EDE7DA IMPERFECTIONS: real skin texture with visible pores and clean studio highlights on her cheek and knuckles, individual frizzy curls catching the key light, genuine creases in the sweatshirt and trousers, honest cardboard fibre and fold marks on the box flaps, a soft crease across the mattress top, fine natural photographic grain. CONSTRAINTS: no watermarks, no extra text beyond the exact strings, no other brand names, no bed frame, no metal base, no legs, no nightstand, no plant, no second person, no plastic skin, no AI smoothing, no beauty filter, no distorted hands, no yellow color cast. OUTPUT: Output in exactly 3200px x 4000px (4:5 portrait format).

Video
Rock Beach - Frame 04
IRIS crosses the mattress with small hops, steps onto the sand, and continues away from camera.
Original prompt
STYLE/CAMERA
Realistic cinematic commercial, natural colors, bright coastal daylight. Vertical 3:4 framing. Handheld camera with subtle, organic micro-movements and slight natural parallax. One continuous shot, no cuts. Camera stays behind and slightly to the side of the woman, following her movement gently while keeping the mattress and her path readable. Do not orbit around her or move in front of her.
AUDIO
Natural beach ambience. <SFX> Gentle ocean waves washing over the shore. <SFX> Soft footsteps and light mattress compression. <SFX> Bare feet landing lightly on sand. <SFX> Gentle sea breeze moving her white shirt. No dialogue. No music.
LIGHTING
Bright natural sunlight consistent with @Image1. Warm, clean summer daylight. Natural shadows on the sand and mattress. Preserve realistic skin tones, white fabric highlights and the blue ocean.
LOCATION
Sunny sandy beach with blue ocean, rocky formations and distant coastline exactly as established in @Image1. Preserve the NUBA mattress, white pillows and loose white sheet. The large orange foreground element remains at the right edge as part of the original composition.
MAIN CHARACTER/CHARACTERS
Woman as in @Image1. Preserve her exact identity, curly dark hair, white lightweight oversized shirt/dress, bare legs and bare feet. She is happy, carefree and innocent. She moves with playful, small, gentle hops rather than energetic jumping. Her arms remain naturally lifted for balance and joy. She walks forward across the mattress toward the far/front edge of the mattress, away from camera.
SCENE FLOW (FULL DURATION TIMELINE)
0.00-1.00: Start from the exact composition of @Image1. The woman stands on the mattress with her arms raised. She begins walking slowly forward across the mattress with a tiny playful hop. Camera is handheld and gently follows her.
1.00-2.00: She takes another small step and soft hop forward. Her movement is light and innocent, with a subtle happy bounce in her body. She keeps both feet on the mattress surface. Camera makes a restrained handheld follow movement.
2.00-3.00: She continues slowly toward the far/front edge of the mattress, away from camera. Her expression and body language remain joyful and carefree. She carefully follows the clear mattress surface and avoids the pillows completely. Her feet never touch the pillows.
3.00-4.00: She reaches the far edge of the mattress, still facing away from camera. She makes one final tiny hop/step on the mattress, then naturally shifts her weight toward the sand beyond the mattress edge. Camera follows with a subtle handheld adjustment.
4.00-5.00: She steps OFF the mattress at the far/front edge and places one bare foot onto the sand, followed naturally by the other foot. The landing is gentle and believable. She does not step on, touch or cross over the pillows. The mattress remains behind her.
5.00-6.00: She continues walking away from camera onto the beach sand, leaving the mattress behind her. She remains happy and relaxed, taking one or two light, playful steps on the sand. Camera gently follows and settles, preserving the beach, mattress and ocean continuity.
CONSTRAINTS
Use @Image1 as the sole visual reference. Preserve the woman’s exact identity, hairstyle, wardrobe, body proportions, mattress, NUBA branding, two white pillows, loose white sheet, beach, rocks, ocean, sky and orange foreground element. @Image1 is a reference-to-video image, not a first or last frame. The woman must travel from the mattress toward the far/front edge of the mattress, away from camera, then step onto the sand beyond that edge. She must NEVER step on, kneel on, sit on, or touch the pillows. Do not make her jump high. Keep all hops very small and physically natural. Preserve realistic foot contact, weight transfer, mattress compression and sand interaction. No cuts, teleportation, morphing, duplicated limbs, altered wardrobe, changed face, extra people, surreal physics, excessive camera shake, camera rotation around her, or movement toward camera.
Video
Mirror Salt Flat - Frame 02
IRIS takes gentle sips of tea while bird shadows pass across the scene and the water reflection moves naturally.
Original prompt
STYLE/CAMERA
Realistic cinematic luxury commercial, natural colors, serene and elegant. Vertical 3:4 framing. Subtle handheld camera with very gentle organic micro-movements, natural parallax and slight breathing in the frame. One continuous shot, no cuts. Preserve the exact composition and low camera perspective of @Image1. The water reflection remains an important visual element throughout.
AUDIO
Natural seaside ambience. <SFX> Very soft water movement and gentle ripples. <SFX> Light sea breeze moving through her robe and the bedding. <SFX> Subtle porcelain cup sounds as she holds and drinks from the tea cup. Natural quiet breathing. No dialogue. No music.
LIGHTING
Bright natural daylight matching @Image1. Soft warm sunlight with clean highlights and realistic shadows. At one moment, the moving shadows of several birds passing overhead travel naturally across her body, robe and the mattress. Only the cast shadows are visible; the birds themselves are never visible anywhere in frame. The bird shadows briefly cross her body and continue across the surrounding mattress/water surface, consistent with the direction of the sunlight.
LOCATION
A tranquil reflective body of shallow water beneath a clear blue sky, with the NUBA mattress resting on the water surface. Preserve the exact waterline, mattress, white bedding, orange pitcher in the foreground, and the woman's reflection in the water from @Image1.
MAIN CHARACTER/CHARACTERS
Woman as in @Image1. Preserve her exact identity, curly dark hair, white robe, seated posture and natural appearance. She holds the small tea cup with both hands. She is calm, peaceful and content. She takes slow, delicate sips of tea, briefly lowering the cup between sips. Her movements are minimal and natural.
SCENE FLOW (FULL DURATION TIMELINE)
0.00-1.00: Begin with the exact composition of @Image1. The woman sits peacefully on the NUBA mattress holding the tea cup near her face. Very subtle handheld movement. The water beneath the mattress shows gentle natural ripples and a soft reflection of the scene.
1.00-2.00: A light sea breeze moves her white robe, hair and loose bedding very gently. She raises the cup naturally and takes a small, relaxed sip of tea. The water reflection shimmers subtly with the movement of the surface.
2.00-3.00: She lowers the cup slightly after the sip and pauses, enjoying the moment. A flock of birds passes overhead outside the camera's view: only their soft, moving cast shadows sweep across her upper body, robe and the mattress. No birds are visible in the sky or anywhere else in frame. The shadows move continuously and realistically according to the sunlight.
3.00-4.00: She takes another small sip, keeping both hands naturally around the cup. The bird shadows continue passing briefly across her body and then move away. The water reflection continuously responds to tiny surface ripples, creating realistic shimmering distortions.
4.00-5.00: She lowers the cup and breathes calmly, enjoying the sea breeze. Her robe and hair move subtly. The white bedding responds gently to the breeze. The bird shadows have passed completely; no birds are visible.
5.00-6.00: She brings the cup close to her chest and settles into a peaceful pose. The water continues its delicate movement and reflection. The handheld camera gently settles without a noticeable zoom, ending on the serene tableau.
CONSTRAINTS
Use @Image1 as the sole visual reference. Preserve the woman's exact identity, face, hairstyle, skin tone, white robe, seated position, tea cup, NUBA mattress, bedding, orange foreground pitcher, water, reflection, sky, lighting and overall composition. @Image1 is a reference-to-video image, not a first or last frame. Keep the water reflection physically coherent and continuously connected to the scene. Keep the sea breeze subtle and believable. She must take gentle, natural sips from the existing tea cup.
CRITICAL: The birds themselves must NEVER be visible. Show ONLY their cast shadows as they pass overhead. The shadows must look like real bird silhouettes projected by sunlight onto her body, robe and mattress, moving naturally across the surfaces and then disappearing. Do not create birds in the sky, bird reflections, bird silhouettes as objects, or flying creatures anywhere in frame.
No added objects or people. No cuts, camera jumps, exaggerated handheld shake, large waves, floating objects, reflection duplication, warped anatomy, cup morphing, wardrobe changes, altered branding, surreal physics or excessive motion.
Video
Green Meadow - Frame 06
IRIS breathes and smiles as the sheet, grass, and her hair move in the same breeze.
Original prompt
STYLE/CAMERA
Realistic cinematic commercial, natural colors and authentic outdoor texture. Vertical 3:4 framing. Subtle handheld camera with gentle organic micro-movements, no exaggerated shake, no artificial camera motion. Start from the exact composition of @Image1 and preserve the framing and visual geometry.
AUDIO
Natural countryside ambience. <SFX> Soft wind moving through the grass and fabric. <SFX> Gentle fluttering of the floating sheet. Distant birds. Natural breathing clearly audible but subtle. No dialogue. No dramatic music.
LIGHTING
Bright natural daylight matching @Image1. Soft, warm summer sunlight with natural cloud diffusion. Preserve the existing highlights, shadows, skin tones, and exposure.
LOCATION
Open green countryside with rolling hills, tall grass, scattered wildflowers, blue sky and white clouds. Preserve the exact environment, bed placement, white pillows, blue NUBA mattress and visible NUBA branding from @Image1.
MAIN CHARACTER/CHARACTERS
The woman in @Image1. Preserve her exact identity, face, hairstyle, skin tone, white/cream lightweight outfit, seated posture and position on the NUBA bed. She remains relaxed and peaceful. She slowly inhales, her chest and shoulders moving naturally, then exhales and develops a gentle genuine smile. Her eyes remain softly closed or relaxed; no direct look into camera. Her hair responds subtly to the breeze.
SCENE FLOW (FULL DURATION TIMELINE)
0.00-1.00: Preserve the exact starting composition of @Image1. The large white sheet already floating above the bed begins a slow, natural billowing motion in the breeze. The woman remains still except for natural breathing. Subtle handheld micro-movement.
1.00-2.00: The sheet ripples and lifts organically, with realistic fabric weight, folds, drag and airflow. The woman takes a slow, visible breath in; her shoulders and chest rise naturally. Camera makes a barely perceptible handheld push-in.
2.00-3.00: She exhales slowly and begins a small, genuine smile. Her head tilts only slightly toward the sunlight. The camera makes a very subtle lateral micro-shift, maintaining the original composition and subject scale.
3.00-4.00: The smile settles naturally. Her breathing continues. Her hair and the grass move gently with the same breeze. The sheet continues floating overhead with continuous, physically plausible motion.
4.00-5.00: The woman remains relaxed, smiling softly. The sheet reaches another gentle crest and falls into new folds without snapping or becoming rigid. Camera continues restrained handheld micro-movement.
5.00-6.00: She remains seated in the same position, peaceful and smiling. The sheet keeps floating naturally overhead. The camera subtly settles, ending close to the original composition. Preserve a calm, effortless final frame.
CONSTRAINTS
Use @Image1 as the sole visual reference. Preserve the woman's identity, appearance, wardrobe, pose, hands, hair, bed, pillows, NUBA branding, landscape, flowers, sky, lighting and composition. Images are references to video, not first/last frames. Do not introduce new people, objects or scenery. Do not alter the NUBA logo or mattress design. Do not make the sheet fly away, stretch unnaturally, become opaque, or move against the wind. Keep fabric, hair, grass and breathing physically realistic. No surreal motion, no morphing, no body deformation, no facial changes, no exaggerated smile, no excessive camera shake, no zoom, no cuts.

Review checklist
Before you publish
Before approving the next NUBA frame
- The mattress remains king size, optic white, square-edged, medium-high profile, and free of buttons or capitonne tufting.
- The navy perimeter band wraps all four sides, with repeated white NUBA wordmarks and one centered embroidered white label patch on each side panel.
- IRIS keeps the same face, deep dark skin with warm undertone, shoulder-length curly chestnut-brown hair, high cheekbones, full lips, beauty mark, and slim frame wherever she appears.
- The mattress sits directly on the named surface without an invented bed frame, headboard, base, or legs.
- The specified saffron-orange foreground object remains heavily out of focus while the mattress, model, and campaign scene keep the requested focus hierarchy.
- Every visible NUBA wordmark, side label, exact text string, product dimension, and output size matches the full prompt for that frame.
- Motion stays within the named action, camera, physics, audio, and preservation constraints, including the Rock Beach pillow rule and the Mirror Salt Flat bird-shadow rule.
FAQ
What should I create before the campaign frames?+
Generate and approve Frame 00, the top, side, and three-quarter NUBA product reference sheet. The process page says this sheet becomes the reference image used to keep the mattress identical across the carousel.
Which model should I use for the still images?+
The supplied guide specifies Riverflow 2.5 for Frame 00 and all seven campaign frames.
Which references should I attach?+
Follow each prompt literally. Frame 00 creates the product sheet; later prompts name a composition reference, the model reference for IRIS where she appears, and the approved mattress reference.
What image formats does the guide specify?+
Frame 00 says 3840px x 2160px landscape, Frame 01 says 2160px x 3840px portrait, and Frames 02-07 say 3200px x 4000px portrait. The Frame 00 footer's vertical wording conflicts with its prompt and is preserved as a source note above.
Which frames have motion prompts?+
Frame 04 Rock Beach, Frame 02 Mirror Salt Flat, and Frame 06 Green Meadow each have an exact six-second Seedance prompt and a supplied video example.
Why do the motion examples say 3:4 when the guide also says 4:5?+
Each motion prompt body explicitly says Vertical 3:4 framing, while the process page and motion-page footers say vertical 4:5. This guide preserves both statements instead of rewriting the source.
