The video shows a close-up of a person's fingernail as they apply a clear coat of nail polish. The brush is dipped into the polish and then carefully applied to the nail, covering it completely. The person's hand is steady, and the application is smooth and even. The nail polish appears to be of a high-quality brand, and the clear coat gives the nail a glossy finish. The video is shot against a white background, which makes the nail stand out.
