In the video, a person is seen drawing a diagram on a white piece of paper. The person uses a yellow pen to draw straight lines and arrows, and writes labels next to the arrows. The diagram appears to be a simple representation of a circuit or a flowchart. The person's hand is steady, and they take their time to ensure that each line and arrow is drawn accurately. The video is shot from a close-up angle, focusing on the person's hand and the paper. The background is blurred, but it appears to be a desk or table.
