The video shows a close-up of a person's hand with a nail polish brush applying a clear coat over a brown nail. The person's hand is resting on a white surface, and the nail polish brush is being held by the person's other hand. The clear coat is being applied carefully to the entire nail, ensuring that it is evenly distributed. The person's hand is steady, and the brush strokes are smooth and precise. The clear coat appears to be of a glossy finish, and it reflects light as it is being applied. The brown nail underneath is already painted with a brown polish, and the clear coat is being applied to give it a shiny finish. The video does not show the entire process of painting the nail, but it does show the final touches of the clear coat being applied.
