突发巨响后的街头手持镜头

从起始帧中的女性开始，以肩膀高度进行一段单一、连续的观察式手持镜头，跟随她在温暖的午后光线中向前穿过拥挤的城市街道。前几秒带有细微自然的手持不稳定感和可见的胶片颗粒。随后，一声突如其来的巨大撞击声和砰响从她身后左侧的画外爆发。她受到惊吓和恐惧，眼睛睁大，身体绷紧，随即略微转身。周围人群受到惊吓、躲闪、转身并开始四散，人们快速跑过前景。摄影师也受到惊吓：画面猛烈震动，明显变得更加晃动，略微倾斜失衡；当人群穿过镜头时，画面短暂地受到动态模糊影响，随后尝试重新构图对准她，同时保持具有反应性和人性化，而不是随机晃动。不得剪切、不得变焦、不得慢动作。
她在整个画面中大致保持相同大小。
从第一帧开始，保留完全一致的女性、深棕色外套、深红色围巾、温暖低饱和的电影质感和胶片颗粒。音频：柔和的街道环境音和脚步声，随后从左侧传来尖锐响亮的金属撞击声或砰响，接着是喘息声、受惊的喊叫声和快速散开的脚步声。

Single continuous observational handheld shot at shoulder height following the woman from the starting frame as she walks forward through the crowded city street in warm late-afternoon light. Subtle natural handheld instability and visible film grain for the first several seconds. Then a sudden loud crash and bang erupts off-camera from behind her to the left. She reacts sharply with surprise and fear, eyes widening and body tensing as she turns slightly. The surrounding crowd flinches, ducks, turns, and begins to scatter, with people rushing across the foreground. The camera operator is startled too: the frame jolts hard, becomes markedly shakier, tilts slightly off-kilter, briefly struggles with motion blur as bodies cross the lens, then tries to recompose on her while staying reactive and human rather than random. No cuts, no zooms, no slow motion.
She remains roughly the same size in frame throughout.
Preserve the exact woman, dark brown coat, deep red scarf, warm muted cinematic texture, and film grain from the first frame. Audio: soft street ambience and footsteps, then a sharp loud metallic crash or bang from the left, followed by gasps, startled shouts, and rapid scattering footsteps.
