Video prompt: A horse and rider jump gracefully over an obstacle in a show-jumping competition, moving as one.
Defect: Deformation (any reason involved with a movement)
Explanation: The horse moves in an extremely unnatural manner, with its body undergoing peculiar distortions, particularly in the four hooves. Toward the end, its head appears to shrink unnaturally. The movement is accompanied by noticeable blurring, further emphasizing the unrealistic portrayal.
