Video prompt: A mountain festival where traditional folk dancers perform in colorful costumes, tapping and twirling under a canopy of stringed lights.
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 dancing movement appears unnatural, with stiff or exaggerated motions that don’t flow smoothly or resemble typical human movement.
