英語プロンプト

30-second horizontal 16:9 realistic smartphone video. Create an authentic, imperfect everyday gym phone recording, as if a friend casually left a phone recording on a nearby bench. Use a standard smartphone camera with mild autofocus hunting, subtle exposure shifts, natural motion blur, compression artifacts, and slightly uneven handheld framing. No polished commercial look. Single continuous take, no cuts, no time jumps. The subject is a clearly adult woman, 18+, with realistic ordinary gym appearance. 00–05s — ARRIVAL The adult woman walks into a nearly empty gym after finishing a difficult set. She places a water bottle and towel beside a bench, sits down heavily, and leans forward with both elbows on her knees. Her breathing is noticeably heavy. Camera remains several feet away at a slightly low angle, as if casually recording from a phone placed on a gym bench. 05–10s — RECOVERY She slowly unscrews the water bottle, takes two small drinks, then pauses with the bottle still in her hand. Her chest continues rising and falling from exertion. She looks down at her hands for a moment, flexes her fingers, then wipes sweat from her forehead with the towel. 10–15s — THE NEXT SET A gym timer or workout screen is visible in the background but remains completely out of focus and unreadable. The adult woman notices the timer, looks at it, gives a small tired smile, and shakes her head as if realizing she has less rest time than expected. She stands up slowly and rolls her shoulders. 15–20s — PUSHING THROUGH She walks toward a cable machine and adjusts the weight herself. Close natural phone framing as she steps into position. She briefly closes her eyes, takes one deep breath, then begins a controlled exercise set. Show realistic physical effort: tightening muscles, sweat collecting around the forehead and neck, slight trembling near the end of each repetition, natural breathing rather than exaggerated acting. 20–25s — FINAL REP The final repetitions become visibly difficult. She pauses halfway through one repetition, breathes hard, regains control, and completes the movement with genuine effort. After finishing, she slowly releases the handle, bends forward slightly, and places her hands on her thighs while catching her breath. 25–30s — QUIET ENDING She grabs the towel, wipes her face and neck, then looks directly toward the phone for a brief moment. With a tired but satisfied expression, she quietly says in a natural low voice: “Okay… that was worth it.” She picks up the water bottle and walks out of frame. End naturally while the camera continues recording for a moment before the clip stops. AUDIO Natural gym ambience only: distant weights being placed down, cable machine sounds, rubber flooring footsteps, ventilation hum, subtle clothing movement, water bottle clicks, realistic breathing, and occasional muffled gym sounds. Dialogue should sound spontaneous and slightly breathless, not scripted or theatrical. VISUAL REALISM Authentic smartphone footage, ordinary gym lighting, realistic skin texture, visible pores, natural sweat, slightly flushed face, damp hair around the forehead, realistic muscle movement, imperfect exposure, mild phone-camera sharpening, compression noise, subtle autofocus changes, believable shadows and reflections. STRICTLY AVOID: cinematic color grading, beauty filters, artificial skin smoothing, dramatic slow motion, music, subtitles, captions, logos, readable text, fake gym equipment, exaggerated muscles, perfect lighting, fisheye distortion, excessive camera shake, unrealistic sweat, duplicated limbs, warped hands, unnatural facial expressions, scene cuts, time jumps, or skipping the described actions.
