The video shows a close-up of a person using a piping bag to apply yellow icing onto a macaron. The icing is being piped onto the top of the macaron in a circular motion, creating a smooth and even layer. The macaron itself is light brown and appears to be freshly baked. The piping bag is held steady as the icing is applied, and the icing is piped in a consistent and controlled manner. The background is blurred, but it appears to be a kitchen counter with other macarons and baking supplies visible.
