Video prompt: A pair of Labradors races along a beach shoreline, kicking up sand as they chase each other joyfully through the surf.
Defect: Deformation (any reason involved with a movement)
Explanation: The two small dogs running on the beach exhibit noticeable distortions, particularly in their limbs. Their legs appear twisted and stretched unnaturally during their movement, resembling an elastic-like deformation rather than a realistic stride. The bending and warping of their limbs deviate significantly from natural canine anatomy, resulting in an implausible visual effect. This distortion disrupts the smooth motion one would expect when dogs are running on a solid surface like sand.
