Giới thiệu phòng ngủ gia đình ngập tràn ánh sáng

Create one continuous 12-second real estate presentation video in a 9:16 aspect ratio. Feature a generic fictional real estate agent presenting a bright family bedroom in a newly finished home. No logos, watermarks, or on-screen text. [00-04s] Start behind the agent at the bedroom doorway with a smooth gimbal follow movement and a natural 35mm lens feel. The agent opens the door fully, steps inside, turns toward camera, and gestures toward the neatly made bed and wide window. Clear midday light fills the room, revealing believable fabric texture, painted walls, timber flooring, and soft curtain movement. [04-08s] Track diagonally past the agent as they indicate built-in storage and a small reading corner, keeping the camera at comfortable eye level and avoiding distortion. The agent maintains a warm, conversational smile. [08-12s] Ease into a gentle upward tilt toward the window and ceiling height, then settle back on the agent as they present the room with an open palm. Keep all movement physically natural and the room uncluttered. Sound design: quiet indoor room tone, soft footsteps, a faint curtain rustle, and light positive acoustic music.
