**EDITING — BACKGROUND CLEANUP ONLY** Use the uploaded video as the only reference. **0:00–0:04:** Keep completely unchanged. **0:05–0:10:** Keep the foreground girl and the buoy exactly as they are. **Remove the two duplicate children appearing behind her — one boy and one girl.** Do not replace them with anything. After removing them, naturally reconstruct the background using only the existing **sea, shoreline, sky and distant tropical scenery**. Keep the background simple and clean. **CRITICAL:** Do not change the girl's face, hair, clothing, position, scale, expression or movement. Do not change the buoy, its position, size or symbol. Do not add any new characters. Preserve the original camera movement, lighting, ocean, beach and 3D animation style. **From 0:05 to 0:10, there must be ONLY the foreground girl and the buoy. The entire background behind her must contain no people or characters.** No duplicated characters, no ghosting, no reflections of characters, no extra limbs, no new objects.
