Video prompt: A magpie flits from branch to branch, collecting shiny objects to add to its stash.
Defect: Deformation (any reason involved with a movement)
Explanation: The bird, as it moves across the tree, undergoes significant body deformation. Its wings appear to stretch and warp unnaturally, while the torso elongates and shrinks in an inconsistent manner. The bird's legs momentarily blend into its body, making them indistinguishable, and the tail feathers flicker as though melting into the background. These exaggerated shape changes disrupt the natural flow of motion, creating an unrealistic and unnatural depiction of the bird's movement.
