The video shows a close-up of a person's hands as they use a piping bag to apply chocolate frosting onto a cake. The cake is round and appears to be on a white plate. The frosting is being applied in a circular motion, creating a spiral pattern on top of the cake. The person's hands are steady, and the frosting is applied evenly and smoothly. The cake itself is not visible, but the frosting is a rich, dark brown color, indicating that it is likely chocolate flavored. The piping bag is held at a consistent angle throughout the video, and the person's movements are precise and controlled.
