提示詞
場景段落 明亮午後人潮擁擠的露天市集街道，寫實都市動作片。兩側排滿水果與布料攤位和一串串燈籠，到處都是購物人潮。一位綁著短辮子的年輕黑人女性自行車快遞員，穿著金絲雀黃雨衣、黑色工作褲、背著黑色小背包，帶著一個棕色小包裹穿過市集，她的金絲雀黃外套在攤位間格外醒目。以 35mm 底片拍攝的真人實拍影像，真實人物，自然的膚質與質感。
正面中景，攝影機架在穩定器上，從第一秒起在她前方以她的步行速度倒退。0–2s: 她朝鏡頭走來，對著耳機麥克風說話。2–4s: 攤位和購物人潮從她身後滑過。4–6s: 她邊說邊笑，揮動手上的包裹。6–8s: 她突然停下聆聽，挑起眉毛。全程：在她前方倒退移動，她的臉朝向鏡頭，一鏡到底。
英文原文（產生範例影片的提示詞）
Scene paragraph A crowded open-air market street on a bright afternoon, photoreal urban action. Colorful stalls of fruit and fabric with strings of lanterns line both sides, shoppers everywhere. A young Black woman bike courier with short braids, wearing a canary-yellow rain jacket, black cargo pants and a small black backpack, carries a small brown package through the market, her canary-yellow jacket bright against the stalls. Live-action footage shot on 35mm film, real people, natural skin and textures.
Medium shot from the front, the camera on a gimbal moving backward ahead of her at her walking pace from the first second. 0–2s: she walks toward the lens, talking into a headset microphone. 2–4s: stalls and shoppers slide past behind her. 4–6s: she gestures with the package, laughing as she talks. 6–8s: she stops short, listening, eyebrows raised. Throughout: backward travel ahead of her with her face toward the lens, one continuous take.

技巧
攝影機在前面倒退著走。這樣邊走邊說的對話，臉一直都看得清楚。
