Video prompt: The dogs, ranging from tiny Chihuahuas to large Golden Retrievers, wag their tails excitedly, their fur gleaming in the sunlight. The children giggle and chatter, occasionally stopping to pet their furry companions or adjust their leashes. In the background, the lush green trees sway gently in the breeze, and a few birds chirp melodiously. Nearby, a family sets up a picnic, spreading a checkered blanket on the grass, while a couple of joggers pass by, nodding and smiling at the playful scene. The air is filled with laughter and the joyful barks of the dogs, creating a vibrant and heartwarming atmosphere.
Defect: Object Merging or Overlapping: Multiple objects may overlap unnaturally, causing visual confusion.
Explanation:  The dogs undergo continuous shape changes while merging with each other, and the child’s body also deforms, occasionally merging with the dogs. This creates an unrealistic effect, as both the dogs and child should maintain stable, distinct forms.
