In the video, a person is seen grating a lemon using a metal grater. The person holds the lemon with one hand and grates it against the grater with the other hand. The grater has multiple holes of different sizes, and the lemon is being grated over the larger holes. The person's hands are visible, but the rest of their body is not shown in the frame. The background is not visible, so it is unclear where the person is located. The video focuses solely on the action of grating the lemon.
