Video prompt: A historic reenactment involving careful choreography, bringing bygone eras to life through recreations of significant events, engaging audiences in narrative interplay woven by actors.
Defect: Deformation (any reason involved with a movement)
Explanation: The people in the distance appear wavy and unstable, as if viewed through water ripples. Their forms blend and ripple together, creating a fluid, indistinct look that lacks clarity and boundary, as if they are undulating within the scene.
