Video prompt: A pair of playful kittens wrestle each other on a soft pillow, a blur of paws and purring mischief.
Defect: Deformation (any reason involved with a movement)
Explanation: The fur patterns and mouths of the two kittens exhibit constant jittery blurring during their movements. This creates a visual instability that makes the details of their features hard to discern, disrupting the natural appearance of their motion.
