Seedance 2.5 プロンプト - 映画的なバックレス運動キャラクター映像

## CHARACTER CONSISTENCY Use the person from `@Image 1` as the exact same real person throughout the entire video. Preserve her facial identity, facial structure, skin tone, hairstyle, hairline and natural appearance. Do not transform her into someone else. Ignore the background, pose and clothing from `@Image 1`. She wears the same outfit throughout the video: a practical dark backless lace-up workout top with secure coverage across the front and shoulders, paired with fitted dark yoga pants. The top has realistic fabric tension and visible lace-up details across the open back. The outfit is functional, non-transparent and appropriate for weight training. Hair is naturally tied back if applicable, with a few realistic flyaway hairs. ## OVERALL LOOK Make this feel like a real everyday gym vlog recorded on an older iPhone, not a cinematic production. 16:9 horizontal, standard 1x phone lens, normal perspective, no fisheye or ultra-wide distortion. Slightly imperfect framing, occasional focus hunting, exposure changes and natural handheld movement. Low-resolution phone-camera character with realistic compression, mild digital noise and imperfect sharpness. Natural skin pores, sweat, flyaway hairs and small imperfections remain visible. Harsh overhead gym lighting with slightly inconsistent white balance. No cinematic color grading, beauty filter, dramatic lighting or polished commercial look. Use one continuous realistic gym environment with cable machines, benches, dumbbells, racks and mirrors. Any logos, signs or readable text must remain blurred or illegible. ## TIMELINE ### 00:00–00:05 — ARRIVAL Start outside the weight-training area. She holds the phone casually while walking into the gym wearing the dark backless lace-up workout top and yoga pants. The framing is slightly imperfect, with natural handheld movement caused by walking. She looks into the lens and gives a small tired smile: “Back day again… honestly, I almost skipped today.” She turns the phone slightly toward the gym floor, briefly showing the busy workout area and cable machines. Natural footsteps, distant conversations, ventilation and gym ambience. ### 00:05–00:09 — WARM-UP Cut to the phone resting on a bench. Medium-wide static view of a lat pulldown station. She enters frame, places a water bottle down and performs a brief, realistic upper-body warm-up before using the machine. She rolls her shoulders, gently stretches her arms overhead, shakes out her hands and checks the cable attachment. She takes a breath and adjusts the seat and thigh pad. A person naturally passes in the distant background. No staged posing. ### 00:09–00:15 — WIDE-GRIP LAT PULLDOWN SET Camera remains propped at a low three-quarter angle, showing her full upper body, the lat pulldown machine and the weight stack. She sits securely, places her thighs under the pad and grips the long bar wider than shoulder width with both hands. Perform a controlled set of wide-grip lat pulldowns. Her movement must be anatomically and physically believable: - She begins with arms extended and shoulders controlled. - She pulls the bar smoothly toward the upper chest while keeping her torso mostly upright. - Her elbows travel down and slightly back. - She pauses briefly at the bottom without pulling the bar behind her neck. - She slowly returns the bar upward under control, allowing the elbows to extend naturally. - The weight stack moves consistently with the cable and does not float, jerk or change shape. Show realistic effort rather than exaggerated acting. Her breathing becomes heavier, her face shows concentration and mild strain, and her shoulders and upper back engage naturally. On the final repetition, she struggles slightly but completes the pull with controlled form, then carefully lets the bar return to the starting position. She releases the bar, remains seated and catches her breath. Sweat begins to appear naturally on her forehead, neck and upper chest. ### 00:15–00:19 — QUICK CHECK-IN She picks up the phone. Handheld close selfie shot. The framing is slightly off-center and the autofocus briefly adjusts between her face and the background. She wipes sweat from her forehead and says naturally: “Okay… that was way harder than I expected.” She gives a short laugh, takes a sip of water and turns the phone back toward the lat pulldown station. No scripted influencer energy; make it feel spontaneous. ### 00:19–00:24 — SECOND ANGLE, SAME EXERCISE Cut to a new static angle with the phone resting against a gym bag. She performs another short set of wide-grip lat pulldowns from a slightly more side-on three-quarter view. The machine, cable, bar, weight stack and her body position remain physically consistent. Show several controlled repetitions with realistic pacing. Avoid excessive range of motion, swinging, leaning far backward, pulling the bar behind the neck or using momentum. The camera stays completely static while her movement remains natural. Other gym members move casually in the distant background. Include authentic cable sounds, light weight-stack contact, footsteps and general gym ambience. ### 00:24–00:27 — POST-WORKOUT MOMENT Cut to a close handheld shot. She sits briefly on the bench beside the machine, breathing heavily. She looks down for a second, then looks back at the camera with a tired smile. Natural sweat, slightly messy hair, visible skin texture and realistic breathing. She quietly says: “Yeah… I’m definitely feeling this tomorrow.” ### 00:27–00:30 — ENDING Final handheld selfie. She remains beside the lat pulldown machine, holding the water bottle in one hand. She gives the camera a tired but amused look, exhales and briefly glances toward the equipment before looking back into the lens. She says softly: “Definitely not skipping back day next time.” End with a small natural camera movement as she lowers the phone. Preserve the imperfect phone-camera framing until the final frame. ## GLOBAL CONTINUITY AND NEGATIVE CONSTRAINTS Keep the same woman, face, hairstyle, body proportions, outfit, gym environment, lighting conditions and phone-camera quality across every shot. The backless lace-up top must remain consistent and physically attached to her body, with no disappearing straps, changing fabric, exposed unintended areas or wardrobe changes. Maintain realistic anatomy, cable tension, machine mechanics, balance, breathing and weight movement. No floating weights, duplicated equipment, warped hands, extra fingers, distorted limbs, impossible joint angles, exaggerated bodybuilder proportions, sudden muscle changes, fake sweat, beauty retouching, cinematic lighting, slow motion, dramatic camera moves, fisheye distortion, readable logos, visible text, staged posing or influencer-style performance.
