Seedance 2.5 马克笔把城市巴士变卡通 奇幻魔法提示词

Magic Pen Street Transport Vlog · 15 Seconds · Vertical 9:16 [STYLE] Live-action + flat 2D anime sticker compositing, first-person street transport magic vlog. 8K photorealistic detail with the authentic look of a real smartphone rear-camera recording. Strong visual contrast between the photorealistic city and flat cartoon vehicles. One continuous handheld smartphone shot. No cuts. No scene transitions. [CAMERA] Raw, unstabilized handheld smartphone footage throughout: natural walking shake, subtle arm movement, occasional autofocus hunting, realistic exposure shifts between bright sky and building shadows, and slight rolling-shutter jelly during fast pans. Natural smartphone HDR colors with soft, realistic tones. The camera quickly whip-pans to follow the marker and each target. [LIGHTING] Late-afternoon sunlight coming consistently from one direction. Every real object and every animated character casts a soft contact shadow matching the direction of the sunlight. [SETTING] One continuous walk through a Korean city neighborhood. A wide urban road with a pedestrian sidewalk, bicycle lane, city buses, parked scooters, and a crosswalk. Everyday street life, with background pedestrians and vehicles moving naturally.

Every transformation follows the exact same sequence: Marker points → Vlogger says “Biu!” → blue hand-drawn sketch lines wrap around the target → ink spreads → the target transforms into a lively flat 2D cel-shaded anime character with bold cartoon outlines.

Characters retain flat sticker-style shading and are never relit by the real-world lighting. Anything they touch reacts with realistic physical interaction. [00:00–00:03] First-person view while walking beside a busy road. The vlogger raises the black marker into frame and points at a passing city bus. “Biu!” Blue sketch lines wrap around the bus. The bus transforms into a giant flat 2D cartoon vehicle with bold anime outlines while maintaining its exact size, speed, direction, and perspective. It continues driving normally through traffic. SFX: Bus engine + marker whoosh + soft cartoon movement sound. [00:03–00:06] The marker quickly swings downward toward a bicycle passing along the bicycle lane. “Biu!” The bicycle transforms into a cute hand-drawn cartoon bicycle. It continues moving at the same speed, its wheels spinning rapidly, with small sketch particles appearing behind it. SFX: Bicycle wheel sound + light sketch rustling. [00:06–00:10] The marker follows the bicycle toward a parked scooter near the s
