Video prompt: A city sidewalk bustling with pedestrians, cyclists weaving through the throng, and street performers drawing in passersby with their lively music.
Defect: Deformation (any reason involved with a movement)
Explanation: The person and bicycle are unnaturally merged together, with the person's legs appearing to blend into the structure of the bicycle. This creates an unrealistic effect, as the person looks like they are walking rather than riding, with the bicycle and legs fused in a way that defies normal behavior.
