Clean the supplied 10-15 second vertical urban-fantasy office video. Remove all visible subtitles, dialogue captions, title-card text, logo-like marks, and small overlay artifacts while preserving the original characters, office-to-cloud transition, golden particle effects, warm light beam, camera framing, timing, and final city-view composition. Reconstruct the background behind each removed text area so the desk, reports, office wall, aurora clouds, bubbles, clothing edges, and glow remain continuous frame to frame. Keep faces, hands, body scale, hair, outfits, particle trails, and lighting stable. Do not rewrite the story, add new text, add a new watermark, blur the whole frame, crop aggressively, change the characters, remove the magic effects, or create smears where text used to be. Deliver a clean version that feels like the original clip was exported without any captions or title overlays.
