In the video, a person is seen cutting a red onion on a wooden cutting board. The person is using a knife to slice the onion into pieces. The cutting board is placed on a table, and there are other pieces of onion already cut on the board. The person's hands are visible, and they are wearing a white shirt. The knife is silver and appears to be sharp as it cuts through the onion easily. The onion is being cut into even slices, and the person is taking care to avoid cutting their fingers. The background is blurred, but it appears to be a kitchen setting.
