Technical Details

Configuration schema

Promptstring

Text prompt describing the video.

Default ValueA busy open-plan office at night, completely empty except for hundreds of computer monitors left on. Each screen displays a different blinking text cursor on a blank document. As the video progresses, the cursors begin typing on their own—single words, then short sentences—filling the screens with fragments of emails, code, poems, and notes. Overhead lights flicker subtly, dust particles float through the air, and the camera slowly moves down the aisle between desks. The glow from the screens reflects off chairs and glass walls, creating a quiet, unsettling atmosphere. Cinematic realism, restrained motion, strong contrast between darkness and screen light, modern near-future tone.
