Generate an 8-10 second video prompt centered on a collapsing ruins escape run. Build it as a reusable video brief with three concrete beats: open by establishing the runner or vehicle, the ancient ruin corridor, and the first stones breaking loose; move into a fast escape through falling columns, dust, and narrow openings with a readable camera flow; end on a stable final frame where the route, subject, and collapsing ruins remain recognizable. Specify pacing, lens feel, camera distance, lighting, debris timing, motion blur, and continuity rules so the output stays readable. Keep the subject, route, props, location, text, and logos editable. Avoid real brand names, celebrity references, fixed IP, readable signage that cannot be changed, real-world hazardous instructions, sudden teleport cuts, inconsistent scale, warped anatomy, and unrelated extra scenes.
