“An empty subway car rattles through the night, lights flickering”

The short prompt, expanded into a shot description (look, camera, timeline, sound) before rendering. Closed models expand prompts themselves, so they get the short one.

Gritty 35mm film look, shot at night with a wide-angle lens; sodium-yellow fluorescent light flickering over cool blue shadows, a muted teal and ochre palette, quiet and uneasy mood. An empty subway car rattles through a dark tunnel at night. Its interior is scuffed grey metal and worn vinyl seats in rows, with handrails gleaming under flickering overhead tube lights. Grime streaks the windows, and beyond the glass, concrete walls and rusted cable conduits blur past in bursts of light from passing signal lamps. No passengers are present; a discarded paper cup rolls slowly across the floor. Camera: Vertical 9:16 framing, a steady handheld shot from the centre aisle, slowly pushing forward down the length of the car as it sways gently with the motion of the train. Timeline: [0s-2s] The car rushes through the tunnel, lights flickering and buzzing as the paper cup rolls across the floor. [2s-5s] The camera drifts toward the far doors, the window reflections shifting as tunnel lights strobe past. [5s-8s] A lone light flickers out at the end of the car, leaving the carriage in brief darkness before the lights stutter back on. Audio: Steady rattle of steel wheels on rails, a high metallic screech on the curves, electrical buzzing from the flickering lights, distant echoing tunnel reverberation. Realistic proportions and physics, consistent interior throughout, no text or subtitles.
