Thi công giấy dán tường tinh tế cho hành lang

Create one continuous 11-second interior transformation video in a 9:16 aspect ratio, designed for a vertical real-estate marketing view. Show a narrow residential hallway with a prepared wall, white trim, hardwood flooring, and a wallpaper roll resting on a protected work surface. The installer wears gloves, safety glasses, long work trousers, and closed-toe shoes. Do not include logos, watermarks, or text. [00-03s] Start with a low forward tracking move using a 24mm lens feel, passing along the floor and rising toward the installer as they lift a pre-cut textured wallpaper sheet into position. Gentle skylight creates soft gradients across the hallway. [03-07s] Move into a slow orbit with a 50mm lens feel as the installer aligns the top edge, presses the paper downward, and smooths toward the sides with controlled strokes. The textured surface catches light naturally without appearing metallic or artificial. [07-11s] Finish with a stabilized backward dolly revealing the completed hallway, clean vertical seams, undamaged trim, and consistent pattern alignment. Keep all movement physically plausible and continuous. Sound design: subtle footsteps, paper unfurling, smoothing-tool passes, and quiet residential ambience.
