Video prompt: A person is digging
Defect: Deformation (any reason involved with a movement)
Explanation: When the person digs into the ground, the shovel in their hand undergoes noticeable shape deformation. The edges of the shovel appear to bend or warp unnaturally, deviating from its rigid structure. This distortion disrupts the realistic depiction of a tool in use, making it appear flexible or inconsistent with its intended physical properties.
