Seedance 2.5 磁悬浮列车穿越时代 电影写实提示词

30s vertical 9:16 first-person smartphone video. One continuous take, no cuts. Cheap phone held chest-height inside a packed maglev train, looking out the left window. Shaky, crooked, blocked by shoulders, rolling shutter, noisy, unstabilized. Train always moves forward. Same carriage and passengers throughout. 0–2s Present day city. Announcement: “Next stop: 1944.” Train jolts. 2–4s Real silver-gray time-mist tunnel swallows the city. Papers and static fragments fly past. 4–8s Emerges at Normandy, June 1944: gray dawn, ships, landing craft, smoke, distant soldiers. No graphic violence. 8–9s Mist again. “Next stop: 1789.” 9–13s Versailles: golden morning, gates, carriages, 1789 crowds. 13–14s Mist. “Next stop: 1776.” 14–18s Philadelphia: Independence Hall, crowd, proclamation. A passenger says “Look.” 18–19s Dark mist. “Next stop: 1184 BC.” 19–23s Troy at night: burning walls, wooden horse, ships. Silhouettes only. 23–24s Sand mist. “Next stop: 2500 BC.” 24–28s Giza: unfinished pyramid, thousands of workers hauling stones. Passenger whispers “Ohh.” 28–30s Train keeps moving past the pyramid. Soft announcement: “Welcome to 2500 BC.” Ends naturally. Diegetic sound only. Light changes with each era through the left window. Every jump is a real 3D mist tunnel, not an edit.
