The video shows a close-up of a person using a piping bag to apply white frosting onto blue macarons. The frosting is being applied in a circular motion, and the person is using a star-shaped nozzle to create a swirl pattern on top of the macarons. The blue macarons are arranged in a row, and the white frosting stands out against the blue color of the macarons. The person's hand is steady, and the frosting is applied evenly across the surface of each macaron.
