In the video, we see a person using a brush to apply a thick, brown substance onto a surface. The substance appears to be a type of mud or clay, and the person is using the brush to spread it evenly across the surface. The brush is being moved back and forth in a smooth, sweeping motion, and the substance is being spread out to cover the entire surface area. The person's hand is visible as they hold the brush, and we can see the texture of the mud as it is being applied. The color of the mud is a rich, earthy brown, and the surface it is being applied to is not visible due to the thickness of the mud. The video does not show any other objects or people, and the focus is solely on the action of applying the mud.
