Describe the original environment, background, stationary objects, surfaces, textures, colors, and lighting using details supported by the reference video.\n\n3.

Exclude shadows and reflections caused by removed subjects when appropriate, while preserving those belonging to objects that remain.\n\n7. Preserve the original camera viewpoint, composition, framing, perspective, camera movement, lighting, exposure, and color balance.\n\n8. Maintain temporal consistency throughout the video. Avoid ghosting, partial remnants, flickering, duplicated objects, warped geometry, and inconsistent textures.\n\n9.
