装修风格瞬切 - 改造前/后 (Renovation Magic) [00-05s] Before State: A static shot of an empty, grey concrete room (rough construction state). Dust particles float in the air. The lighting is flat and cold. A "scan line" visual effect moves vertically across the screen. [06-10s] Magic Transformation: As the scan line passes, the room transforms instantly into a fully furnished Scandinavian style living room. Warm wood flooring appears, walls turn creamy white, and a cozy beige sofa materializes. Plants pop up in the corners. [11-15s] Alternative Style: The scan line moves again, changing the style to "Modern Industrial." The walls become exposed brick, the floor turns to polished concrete, and leather furniture appears. This demonstrates the design versatility. Text overlay: "One Space, Infinite Styles | Virtual Staging." High-tech visualization style.
