Video prompt: The room is filled with the scent of pine from the towering Christmas tree standing proudly in the corner. The child stretches on tiptoes, reaching up to hang the ornament on a high branch, their face glowing with concentration and joy. As they step back to admire their handiwork, the soft notes of a holiday tune play in the background. With a beaming smile, the child picks up a beautifully wrapped present, its paper shimmering under the warm glow of the lights, and turns to the camera. They hold the gift up proudly, their eyes sparkling with excitement and anticipation, as if sharing a secret with the viewer.
Defect: Object Merging or Overlapping: Multiple objects may overlap unnaturally, causing visual confusion.
Explanation:  The hand, gift box, and Christmas tree merge together, creating an unrealistic effect, as all three elements should remain distinct and separate.
