如何用一张照片制作「首尔的一天」AI 视频：Seedance 提示词与真实案例

Use the uploaded photo as the exact character reference. Preserve the same face, hairstyle, skin tone, body proportions, outfit, accessories, and identity throughout the entire video. No character redesign, wardrobe change, facial change, or identity drift.

Location: A quiet older residential neighborhood in Seoul during a warm summer afternoon. Narrow concrete alleys, low-rise apartments, rooftop terraces, external staircases, potted plants, laundry lines, parked bicycles, utility poles, overhead wires, mature trees, old walls, and a tiny neighborhood shop. Lived-in, peaceful, and authentic. No tourist landmarks, crowds, advertisements, recognizable brands, or polished commercial activity.

Camera style: Raw footage recorded by a friend using a cheap early-2000s consumer DV camcorder. Natural handheld shake, imperfect framing, autofocus hunting, slight exposure shifts between sunlight and shade, faded colors, soft contrast, mild digital noise, natural motion blur, imperfect white balance, accidental zooms, and subtle camera-handling noise. The camera operator occasionally reacts late or briefly loses focus. No stabilization, gimbal, drone, slow motion, cinematic choreography, dramatic lighting, HDR, or modern commercial color grading.

Create a 15-second, 16:9 ultra-realistic early-2000s DV home video using the uploaded photo as the exact character reference.

SUBJECT
Preserve the same face, hairstyle, skin tone, body proportions, casual outfit, and identity throughout. Natural skin texture, relaxed expression, no beauty filter, no identity drift or wardrobe change.

LOCATION
A quiet older Seoul residential alley on a warm late-summer afternoon: narrow concrete lane, low-rise apartments, potted plants, bicycles, utility poles, overhead wires, leafy trees, and old walls. No landmarks, crowds, advertisements, or recognizable brands.

CAMERA
Friend-recorded footage from a cheap early-2000s consumer DV camcorder. Handheld shake, imperfect framing, autofocus hunting, faded colors, soft contrast, slight exposure shifts, mild digital noise, natural motion blur, imperfect white balance, and one awkward accidental zoom. No stabilization, gimbal, drone, slow motion, cinematic lighting, HDR, or modern commercial color grading.

00:00–00:04 — The subject walks slowly down the lane holding a cold bottled drink. A breeze moves their hair and clothes. The camera briefly struggles to focus.

00:04–00:08 — A dry leaf lands on the subject's shoulder. They do not notice at first. The camera operator quietly laughs.

00:08–00:12 — The subject notices the leaf, removes it, looks toward the camera with a mildly embarrassed smile, and laughs naturally.

00:12–00:15 — The subject continues walking, turns back for a tiny wave, then looks away. The recording abruptly cuts to black mid-motion. No fade-out.

AUDIO
Natural location sound only: footsteps, distant traffic, summer insects, leaves, wind, bicycle bell, neighborhood voices, and subtle camera-handling noise. No music, narration, subtitles, captions, logos, watermarks, or artificial sound effects.

REALISM
Believable walking, hand movement, hair, clothing, leaf physics, and foot contact with the ground. No distorted hands, extra fingers, duplicated people, teleportation, floating objects, CGI appearance, exaggerated acting, or sudden transformations.

Create a 30-second, 1080p, 16:9 ultra-realistic early-2000s DV home video showing an ordinary summer afternoon in the life of the person in the uploaded reference photo. The footage should feel spontaneous, intimate, imperfect, and genuinely observed rather than performed.

MAIN SUBJECT
Use the uploaded photo as the exact character reference. Preserve the same face, hairstyle, skin tone, body proportions, casual outfit, shoes, bag, accessories, and identity from beginning to end. Natural skin texture, minimal styling, relaxed expressions. No character redesign, wardrobe change, facial change, or identity drift.

LOCATION
A quiet older residential neighborhood in Seoul: narrow concrete alleys, low-rise homes, rooftop terraces, external staircases, potted plants, laundry lines, parked bicycles, utility poles, overhead wires, mature trees, old walls, and a tiny neighborhood shop. Authentic and lived-in. No crowds, tourist landmarks, advertisements, recognizable brands, or polished commercial activity.

CAMERA STYLE
Raw personal footage recorded by a friend using a cheap early-2000s consumer DV camcorder. Natural handheld shake, imperfect framing, autofocus hunting, exposure shifts between sunlight and shade, faded colors, soft contrast, mild digital noise, natural motion blur, imperfect white balance, accidental zooms, and subtle camera-handling noise. The camera operator sometimes reacts late or briefly loses focus. No stabilization, gimbal, drone, slow motion, cinematic choreography, dramatic lighting, HDR, or modern commercial color grading.

00:00–00:05 — LEAVING HOME
The subject steps out of an old apartment, checks their keys, adjusts their bag, notices the camera, gives a small smile, and starts walking down the lane. The camera takes a moment to find focus.

00:05–00:10 — THE COLD DRINK
At a tiny neighborhood shop, the subject buys a cold bottled drink. Outside, they press the bottle briefly against their cheek because of the summer heat and laugh at the camera operator's awkward zoom.

00:10–00:15 — A SMALL INTERRUPTION
While walking through a quieter alley, a bicycle passes. The subject steps aside naturally, waits, and continues. A breeze moves their hair and clothes. They glance back but do not pose.

00:15–00:20 — THE LEAF
The subject sits on a low wall beside a small apartment garden. A dry leaf lands in their hair. The camera operator points it out. The subject removes it and gives the camera an embarrassed, amused look.

00:20–00:25 — SUMMER RAIN
A light summer shower suddenly begins. The subject looks toward the sky, laughs, protects the drink with one hand, and walks quickly toward a covered entrance. Show believable rain, wet concrete, soft reflections, damp hair, and realistic foot contact.

00:25–00:30 — GOODBYE
Under the apartment entrance, the subject catches their breath, wipes rain from their forehead, gives a small genuine smile, and says, “See you tomorrow.” They walk inside. The camera remains pointed at the closing door for one second, then abruptly cuts to black mid-motion. No fade-out.

AUDIO
Natural environmental audio only: footsteps on concrete, distant traffic, birds, summer insects, leaves, bicycle wheels, shop refrigerator hum, bottle opening, light rain, water dripping from rooftops, quiet neighborhood voices, and subtle camera-handling noise. Dialogue should sound casual and local. No music, narration, soundtrack, subtitles, captions, logos, watermarks, or artificial sound effects.

CONTINUITY AND PHYSICAL REALISM
Maintain believable anatomy, movement, object permanence, clothing, hair, rain interaction, reflections, and environmental continuity. Hands and fingers remain natural. The drink stays a separate physical object and never intersects with the face or hand. No duplicated people, distorted anatomy, teleportation, disappearing objects, floating objects, sudden transformations, or CGI appearance.

FINAL FEEL
Like a forgotten personal recording of an ordinary summer day. Not a commercial, fashion film, music video, or travel advertisement. Quiet, warm, nostalgic, spontaneous, and deeply human. The charm comes from small moments and the feeling that the camera happened to be there.

Keep the same two people throughout. Preserve both faces, hairstyles, body proportions, outfits, accessories, and relationship continuity. Their chemistry should feel familiar and unstaged. Use small physical interactions—passing a drink, briefly blocking the camera, pointing out a leaf, sharing a laugh—rather than exaggerated romantic poses. No face swapping, duplicated people, wardrobe changes, or sudden changes in height and age.
