Remont ze skórzaną sofą i marmurową podłogą

Use the input video as the exact source and preserve the original camera movement, timing, composition, room layout, lighting, shadows, furniture positions, and all objects. Only edit two materials in the living room: 1. Replace the light fabric sofa on the right side of the room with a rich brown leather sofa. Keep the exact same sofa shape, size, position, cushion layout, armrests, backrest, and perspective. The new sofa should look like realistic brown leather, with natural leather grain, subtle wrinkles, stitching, soft glossy highlights, and physically believable reflections from the window light. 2. Replace the visible warm wooden floor with polished white marble flooring. Keep the exact same floor plane, perspective, scale, and room geometry. The marble should be white to light gray with natural subtle veins, realistic seams, and controlled polished reflections. The marble reflections should respond to the window light, furniture legs, plants, sofa base, and room shadows. Everything else must remain unchanged: the window, curtains, walls, wall art, TV, TV console, plants, rug, coffee table, books, radiator, shelves, doorframe, lighting, shadows, camera motion, and overall warm interior atmosphere. The rug and coffee table stay exactly where they are, on top of the new marble floor. The edit should look like a realistic interior renovation, not a new generated room. Maintain temporal consistency across the full video. The sofa and floor materials must remain stable from frame to frame with no flickering, warping, melting, or object changes. Preserve the original video’s natural daylight, warm tone, soft shadows, lens behavior, and smooth camera movement. Negative Prompt Do not change the room layout. Do not move furniture.
