This prompt is written directly in JSON structure: subject, scene, and camera are described as separate fields for the rider crossing the city. In the ongoing debate between structured prompts and natural-language prompts, this is a sample from the structured camp — a 34-second finished clip.

"video_generation": { "subject": { "character": "Young urban man, high flat-top fade, goatee, neck and arm tattoos, silver hoop earrings, geometric reflective sunglasses", "clothing": "White and beige varsity jacket with '38' on sleeves, black shorts, white socks", "vehicle": "Matte black fixed-gear bicycle" }, "scenes": [ "Close-up of a hand holding a smartphone displaying a glowing red heart.", "Character sips a pink iced drink, smirks, and gets on his bicycle.", "Aggressive, fast-paced cycling through sunlit city streets, weaving through traffic.", "Character rides quickly down a flight of concrete stairs.", "High-speed navigation through a crowded Asian street food market, bumping a man and causing noodles to fly in slow motion.", "Riding up stairs and launching off a dirt jump ramp with a city skyline in the background.", "Character skids to a perfect stop in front of a modern glass building where a woman is waiting." ], "camera_work": "Dynamic tracking shots, fast-paced action, brief slow-motion emphasis during the food spill", "style": "Ultra-realistic 3D animation, cinematic lighting, vibrant colors, motion blur", "render_settings": { "resolution": "8K", "quality": "Cinematic, high-detail", "aesthetic": "Hollywood movie" } } }
✍️ Editor’s Notes

这条最值得注意的是它的书写格式本身——不是自然语言描述,而是直接一段JSON片段(subject/clothing/vehicle/scenes/camera_work/style/render_settings),而且开头缺了外层键名和左花括号,明显是从更大的结构化数据里截出来的一段,说明作者在用接近API调用的方式驱动模型,把人物设定、场景列表、镜头语言和渲染参数当成独立字段分别填写,而不是揉成一段话。七个scenes条目本身极其电影化——从爱心notification到跳伞台阶再到闯入夜市撞飞面条,动作场景按镜头顺序编号排列,跟前面几条中文长词的分镜写法本质相通,只是外壳换成了程序员更熟悉的键值对结构,这提示GPT Image 2 + Seedance 2.5这套组合可能同时支持结构化JSON输入和自然语言输入两种解析路径。
