Seedance 2.5, 720p, 30s, 16:9, One continuous 30-second live-action sequence on an open-air skyscraper construction floor high above a city at golden hour, following a young woman with athletic build, blonde updo hairstyle, minimal makeup, barefoot, wearing only a red leotard. Keep her exact face, hair, and red one-piece leotard outfit in every shot, no costume change, no second person, no safety harness. Exposed steel columns, hanging rebar, crane cables, concrete dust in warm sidelight, wind moving loose plastic sheeting. Photoreal cinematic sports film, sharp detail, natural motion blur only on fast limbs. 0-4s: Medium close-up, locked camera. She faces the lens with a slight confident smile and says “Let’s go” with clear, short, energetic lip sync; she slaps her hands together as if dusting them off. Hard cut. 4-11s: Low tracking shot racing beside her as she sprints across the open deck, vaults a stack of lumber, plants one hand, and aerials over a gap between floor plates. Camera dips under her and rises with her landing. Wind and foot impacts. 11-18s: Wide crane shot swinging around a steel column. She leaps, catches an overhead scaffold bar, swings once, releases into a layout flip, catches the next bar, and drops into a roll. Camera orbits her from below while city and sky trade places behind her. Cable creak and a sharp exhale. 18-24s: Steadicam follow from behind, then a whip-pan to her front as she runs up a slanted beam, pushes off, and twists through open air onto a big steel I-beam hanging level from the crane. She lands in a gymnast mount. Slow push-in. 24-30s: The suspended beam becomes her balance beam, high over the deck. She does a controlled walk, a full turn, a leap, then an Olympic-style spin into a backflip off the end. She lands on a wooden pallet stacked with bags of concrete mix, sticks the landing with no extra step, and holds a clean gymnast Y pose, arms up, chin lifted. Camera orbits once and settles on a low hero angle. Final frame held. City wind ambience, distant crane sounds, footsteps and impacts, cable creak, her dialogue and breathing — full sound design, no music, no subtitles, no logos.

Seedance 2.5, 720p, 30s, 16:9, 一个连续的 30 秒真人实拍长镜头，场景为黄昏金色时刻一座高空摩天楼的露天施工楼层，跟随一位体格健硕的年轻女子：金发盘发发型、淡妆、赤脚、只穿一件红色连体紧身衣。每帧都须严格保持相同的面孔、发型与红色连体紧身衣装扮，不得更换服装，不得出现第二人，不得使用安全带。裸露的钢柱、下垂的钢筋、塔吊钢缆、暖色侧光中的混凝土粉尘、被风吹动的松散塑料布。照片级真实感的体育题材电影质感，细节锐利，快速运动的肢体仅保留自然运动模糊。 0-4s：中近景，固定机位。她面向镜头，带着一丝自信的微笑，用清晰、简短、充满活力的对口型说 “Let’s go”；同时双手相拍，像在掸掉手上的灰尘。硬切。 4-11s：低位跟拍镜头在她身旁疾驰，她冲刺穿越露天平台，翻越一摞木材，单手撑地，在楼板之间的缺口上方腾空翻越。镜头俯冲到她的下方，并随她的落地回升。风声与脚步冲击声。 11-18s：环绕钢柱摆动的宽幅吊臂镜头。她跳跃，抓住头顶的脚手架横杆，荡一次，松开进入直体翻腾翻转，抓住下一根横杆，再下落到一个滚翻。镜头从下方环绕她，城市与天空在她身后交替。钢缆吱嘎声和一声短促的呼气。 18-24s：斯坦尼康从后方跟随，然后急速甩镜摇到她正面，她沿一根倾斜的钢梁向上奔跑，蹬离，在开放空中扭转，落到一根由塔吊水平悬挂的大型钢工字梁上，以体操运动员的姿势稳稳落定。缓慢推近。 24-30s：悬挂的钢梁变为她的平衡木，高悬于平台之上。她完成一段受控行走、一整圈转体、一次跳跃，再以奥运风格的旋转接团身后空翻腾出梁端，落在一摞堆满袋装混凝土砂浆的木托盘上，落地稳健无需多余步伐，最后定格为干净利落的体操 Y 姿势，双臂高举，下巴抬起。镜头环绕一周，定格于低位英雄机位低角度。最后一帧保持。 城市风的环境音、远处的塔吊声、脚步声与撞击声、钢缆吱嘎声、她的对白与呼吸——完整音效设计，无音乐，无字幕，无标志。
