Video prompt: an animation of a large, modern stadium filled with people cheering and enjoying the game.
Defect: Deformation (any reason involved with a movement)
Explanation: The person's arms and body appear extremely blurred, with their arms moving in a rigid, mechanical manner. Meanwhile, in the stands, the spectators watching the game become distorted and blur into a single, indistinct mass, making individual figures hard to distinguish. This merging creates a hazy, unnatural appearance among the crowd.
