2. GPT Image 2.5 기반 5대 시각 레퍼런스 시트 생성

Seedance 2.5의 아이덴티티 고정(Identity Lock)을 위해 GPT Image 2.5로 5종의 고해상도 시각 에셋을 준비합니다.

인물 레퍼런스 시트 (Character Sheet)

인물의 주근깨, 헤어 컬러(발레아쥬), 의상 디테일을 4분할 패널(클로즈업 18° FOV, 3/4 측면 29° FOV, 전신 전면 47° FOV, 전신 후면 47° FOV)로 구성하여 일관성을 확보합니다.

SCENE CONTEXT
A photoreal character reference sheet of one young woman, built from the attached first-frame selfie, for identity lock in a UGC try-on video.

SUBJECT
A young woman in her mid-twenties, slim build. Face: fair skin with a warm golden undertone and a soft capillary flush across the cheeks and nose, dense natural freckles scattered across the nose bridge, both cheeks and the upper lip area, hazel-green almond eyes with a warm golden ring around the pupil, thick natural brows with a fairly straight line and a soft arch at the tail, straight narrow nose with a slight sun-lit sheen on the bridge, full lips in a glossy rose-nude with a defined cupid's bow, dewy bare skin with no visible foundation. Hair: long layered light-brown hair with caramel and honey-blonde balayage streaks, a clean center part, slightly piecey loose waves, soft face-framing strands falling past the collarbones. Hands: short soft almond nails in a sheer nude, two thin stacked silver band rings on the ring finger. Outfit: an oversized burgundy chunky-knit funnel-neck sweater in a fuzzy mohair-blend yarn with a soft halo of fibres, cream relaxed wide-leg trousers, bare feet. 100% matches the reference.

LAYOUT
Four panels side by side, 100% consistent across all 4 shots: face close-up at 18° FOV looking to the lens, head and shoulders three-quarter left at 29° FOV, full body front at 47° FOV, full body back at 47° FOV.

OPTICS
Natural perspective, deep focus, high micro-contrast, fine skin texture preserved.

CAMERA
Eye level, subject centred in each panel, straight rectilinear framing.

BACKGROUND
Seamless neutral light-grey cyclorama, soft contact shadow at the feet.

LIGHTING
Even soft studio softbox key from the front-upper, gentle fill, WB 5200K, freckles and skin texture fully readable.

MATERIAL
Pore-level realism: vellus hair along the jaw and hairline, asymmetric freckles, capillary flush, wet living eyes with catch-lights. Fuzzy knit halo and individual yarn loops readable on the sweater.

STYLE
Photoreal editorial studio photography, 8K, no 3D render.

POSITIVE LOCKS
Single subject, no extra people, no text overlays, no watermark. Face, freckles, eye colour, brows, lips and hair identical in all four panels. Eyes stay natural, no eye glow.

시작 프레임 셀피 (Start Frame)

스마트폰 광각 렌즈 특성과 오후 창가 자연광의 질감을 프롬프트에 직접 기재하여 필터 없이 사실적인 스마트폰 카메라 질감을 구현합니다.

A close-up straight-on smartphone selfie of the same young woman, taken at arm's length with a wide-angle phone lens, placed in the right foreground of a sunlit contemporary living room. She has hazel-green eyes, sun-kissed light-tan skin with faint freckles across the nose and cheeks, and long straight balayage hair with darker brown roots and honey-gold highlights, one loose strand framing the left side of her forehead. She rests her cheek gently on her left palm, two minimalist silver rings on her fingers, glossy pink lips, calm introspective gaze into the lens. An oversized chunky deep-burgundy cable-knit sweater with ribbed cuffs fills the lower half of the frame. Direct mid-afternoon window sunlight rakes across her face, crisp shadows and warm highlights. Behind her, softly blurred: a beige pillow on a cream couch, a small bright window, a large arc of sunlight falling on the off-white wall. Palette of 50% creamy off-white and warm greige, 35% rich burgundy wine, 15% golden beige and honey. Moderate shallow depth of field, sharp detail on eyes and knit, slight wide-angle curve in horizontal lines, natural skin texture with visible pores, cozy quiet mood.

공간 레퍼런스 시트 (Location Sheet)

햇빛이 비치는 미니멀 거실 공간을 인물 없는 상태의 2패널(84° FOV 광각 및 47° FOV 중경)로 생성해 공간 구조와 광원 각도를 고정합니다.

SCENE CONTEXT
A photoreal location reference plate of the sunlit apartment living room seen in the attached first-frame selfie, empty, late afternoon.

LOCATION
A calm minimal apartment living room. A low deep sofa in cream-beige textured bouclé runs across the midground, with a square tan cushion with a soft satin sheen at the camera-left end and a second cream cushion beside it. Behind it a smooth warm off-white plaster wall. High on the camera-left wall, a deep-set square window with a thick white reveal frames a white modern apartment building with rows of windows, a bare winter tree and clear pale-blue sky. Pale natural oak floorboards with a soft matte finish. A slim black phone tripod stands empty in the foreground, about two metres in front of the sofa. Nothing else in the room, uncluttered and airy.

LAYOUT
Two panels: wide establishing view at 84° FOV from chest height facing the sofa, and a medium view at 47° FOV of the sofa and wall.

OPTICS
Deep focus, zero distortion, straight rectilinear edges.

LIGHTING
Low golden late-afternoon sun from camera-right front, entering at a steep raking angle, throwing a hard bright rectangle of warm sunlight across the wall behind the sofa and a softer patch across the sofa cushions, deep soft warm shadow on the camera-left wall. Fine dust visible in the beam, faint atmospheric haze. WB locked 4600K, warm amber sun against cooler ambient shadow, soft highlight roll-off.

COLOR GRADE
Honey gold in the sun patch on the plaster, cream and oat in the bouclé, tan sheen on the cushion, cool pale blue in the window sky, color tied to source and surface, not a flat list.

STYLE
Photoreal interior photography, 8K, natural daylight rendition, fine grain.

POSITIVE LOCKS
No people, no text overlays, no watermark. Room layout, window position and sun direction 100% consistent across both panels.

의상 레퍼런스 시트 (Cloth Sheet)

고스트 마네킹 스타일로 제품(네이비/크림 스트라이프 니트 베스트)의 스트라이프 비율, 골지 텍스처, 넥라인 바인딩을 3패널로 명시합니다.

SCENE CONTEXT
A photoreal garment reference sheet of one knit vest, ghost-mannequin style, for a UGC try-on video.

SUBJECT
A cropped fitted sleeveless knit vest in fine vertical rib-knit. Wide horizontal stripes alternating deep navy and warm cream, starting and ending in navy, with a navy ribbed hem band. A solid navy notched lapel collar folds over into a deep V neckline, with a navy rib binding around the neck and the armholes. High cut armholes, close body that follows the bust and nips in at the waist, hem ending at the high waist. Soft matte cotton-blend surface, no print, no logo on the outside. A small off-white woven brand label is stitched into the inside back neck. 100% matches the reference.

LAYOUT
Three panels: front ghost-mannequin at 47° FOV, back ghost-mannequin at 47° FOV, macro detail at 12° FOV of the collar fold and rib texture.

BACKGROUND
Seamless neutral light-grey cyclorama.

LIGHTING
Even soft studio softbox key from the front-upper, gentle raking fill that lifts each rib in relief, WB 5500K.

MATERIAL
Individual rib columns and knit loops readable, crisp clean stripe edges, soft collar roll.

STYLE
Photoreal editorial e-commerce product photography, 8K.

POSITIVE LOCKS
No model, no hanger, no text overlays, no watermark. Stripe count, stripe widths and collar shape 100% consistent across all panels.

브랜드 라벨 매크로 시트 (Brand Logo)

의류 넥라인 안쪽에 박음질된 브랜드 라벨(ZARA)의 직조 질감과 세리프 폰트를 매크로 2패널(12° FOV 및 18° FOV)로 렌더링합니다.

SCENE CONTEXT
A photoreal macro reference of one woven brand label stitched into the inside back neck of a navy and cream striped rib-knit vest.

SUBJECT
A small square woven satin label in off-white with a black high-contrast serif wordmark reading ZARA, clean folded edges, fine visible stitching along the top edge, one lower corner curling slightly away from the fabric. It sits on the navy rib binding of the inside back neck, with the cream and navy stripes of the vest visible soft around it. 100% matches the reference. Take only the label from the reference, never the black leather or dark satin lining around it.

LAYOUT
Two panels: straight-on macro at 12° FOV, and an angled macro at 18° FOV with fingers folding the neck open.

BACKGROUND
The vest fabric itself, softly out of focus beyond the label.

LIGHTING
Soft warm window light from the upper right, WB 4800K, off-white label bright without clipping.

STYLE
Photoreal macro product photography, 8K, true woven thread texture.

POSITIVE LOCKS
Wordmark straight, sharp and fully legible in both panels. No extra text, no watermark.

3. Seedance 2.5 비디오 합성 및 @레퍼런스 바인딩

준비된 5장의 레퍼런스 이미지를 Seedance 2.5의 @Image 참조 태그로 연결하고, 액션 시퀀스와 공간 블로킹을 정의합니다.

SCENE CONTEXT
Real, unedited vertical smartphone footage of a young woman filming a fashion try-on alone in her sunlit minimal apartment at golden hour, posted as an organic creator video. She opens with a close handheld selfie on the sofa and calmly tells the lens she just tried Claude Sonnet 5.5. She stands, clips the phone onto a low black tripod, picks up a navy and cream striped rib-knit vest, shows it front and back, steps close and holds the inside neck label to the lens, pulls her burgundy sweater off over a nude seamless tank, slips the vest on, does an outfit check, then walks back up, lifts the phone off the tripod and softly reveals in a close selfie that Sonnet 5.5 wrote the whole video. Every frame must be indistinguishable from real phone footage.

ACTIVE REFERENCES
@[Image 1](image_1) CHARACTER. Face, dense natural freckles across the nose bridge and both cheeks, hazel-green eyes with a warm golden ring around the pupil, thick straight natural brows, glossy rose-nude lips with a defined cupid's bow, straight narrow nose, center-parted light-brown hair with caramel balayage and soft face-framing strands, slim build, oversized burgundy chunky mohair-blend funnel-neck sweater, cream wide-leg trousers, bare feet, thin stacked silver rings. 100% matches the reference.

Long cream bouclé modular sofa with a tan silk cushion at camera-left and a cream lumbar cushion, warm off-white plaster wall, deep-set square window with a thick white reveal high at camera-left framing a white apartment building, a bare tree and blue sky, sun from camera-right casting a four-pane window-grid of light across the wall, pale oak plank floor with long streaks of sun, slim black tripod. 100% matches the reference.
@[Image 3](image_3) BRAND LABEL, LABEL ONLY. Off-white woven square label with the black serif ZARA wordmark, fine top stitching, one lower corner softly curled. Take only the label, stitched into the inside back neck of the vest. 100% matches the reference.
@[Image 4](image_4) FIRST FRAME. The exact opening selfie: framing, slight high angle, hand at cheek with the silver rings, sun on the camera-right side of her face, window at upper camera-left, curved patch of sun on the wall behind her. 100% matches the reference.
@[Image 5](image_5) GARMENT, THE VEST. Cropped fitted sleeveless rib-knit vest in wide horizontal stripes, navy at the shoulders, then cream, navy, cream, and a navy ribbed hem band, solid navy notched lapel collar folding into a deep V, high armholes, small plain label at the inside back neck. 100% matches the reference.

LOCATION MAP
Foreground: the slim black tripod about two metres from the sofa, and the woman moving between the tripod and the sofa on the oak floor. Midground: the long cream bouclé sofa, the tan silk cushion at camera-left, the folded striped vest waiting on the seat cushion beside her. Background: the off-white plaster wall carrying the warm window-grid of sunlight, the deep-set window at upper camera-left.

FIRST FRAME / BLOCKING
Non-empty opening frame: identical to @[Image 4](image_4). Close handheld selfie at arm's length from a slight high angle, she sits sideways on the sofa in the burgundy sweater, cheek resting on her fingertips, lips softly closed, golden sun raking across the camera-right side of her face, window at upper camera-left. She is already in motion, a slow breath lifting her chest as her eyes settle on the lens.
