Video prompt: A vibrant hot air balloon fiesta, where dozens of balloons of all shapes and colors ascend into the early morning sky, creating a spectacular array of floating art.
Defect: Deformation (when Object is involved in an act,  anything in this process that's weird. e.g. people walk into a wall. "Walk" is an act)
Explanation: The passenger basket beneath the hot air balloon undergoes unnatural shape changes as it ascends, creating an unrealistic effect, as the structure should remain stable and consistent.
