In the video, a person is seen cooking in a pan. The person is adding diced celery to the pan, which already contains onions. The celery is being added from a clear plastic container. The pan appears to be on a stove, and the person is using a spatula to stir the ingredients. The person's hand is visible, and they are wearing a ring. The celery is bright green and appears fresh, while the onions are white and translucent. The pan seems to be non-stick, and the stove is not visible in the frame. The person's movements are deliberate as they add the celery to the pan.
