The video shows a close-up of a ceiling with a spray gun being used to apply a white substance, likely spackle, to the surface. The spray gun is being moved in a steady, circular motion, and the white substance is being applied in a consistent, even layer across the ceiling. The ceiling itself appears to be in the process of being repaired or finished, with the white spackle covering the entire visible area. The spray gun is held by an unseen person, and the video focuses solely on the action of spraying the substance onto the ceiling.
