Create one continuous 12-second real estate presentation video in a 16:9 aspect ratio. Feature a generic fictional real estate agent in professional, approachable clothing, standing in front of a modern suburban home with natural stone, warm wood, and clean landscaping. No logos, watermarks, or on-screen text. [00-04s] Use a gentle forward dolly with a natural 35mm lens feel as the smiling agent opens the front door and gestures inside, maintaining direct eye contact with the camera. Soft morning sunlight creates realistic highlights on the facade, while the shaded porch remains evenly exposed. [04-08s] Continue through the doorway in the same uninterrupted movement; the agent walks backward carefully into the entry hall and presents the open-plan living area with one welcoming hand gesture. The camera adjusts smoothly to the interior exposure. [08-12s] Arc slightly to the agent’s side, revealing the living room, large windows, and neutral furnishings as the agent turns toward the space and smiles. Keep body movement natural, materials believable, and architectural proportions realistic. Sound design: light footsteps, subtle door hinge movement, soft outdoor ambience, and calm upbeat instrumental music.
