Generate an 8-10 second video prompt centered on a brutalist rooftop sunrise scene. Build it as a reusable video brief with three concrete beats: open by establishing the subject, rooftop setting, and visual promise; move into the main action, transformation, or reveal with a clear camera path; end on a stable final cinematic frame that can work for a landing page preview, product showcase, or social cutdown. Keep the stark architectural mood grounded through concrete beats, controlled camera motion, consistent scale, and visual rules that prevent random symbols from overtaking the concept. Specify pacing, lens feel, camera distance, sunrise lighting, motion blur, and continuity rules so the output stays readable. Keep all subjects, props, locations, text, and logos editable. Avoid real brand names, celebrity references, fixed IP, readable signage that cannot be changed, unsafe action, sudden teleport cuts, inconsistent scale, warped anatomy, and unrelated extra scenes.
