The video shows a person's hand holding a piece of paper with a drawing on it. The drawing appears to be of a mechanical device, possibly a robotic arm or a mechanical arm. The person's hand is moving the paper around, presumably to show different angles and details of the drawing. The drawing is done in pencil and is quite detailed, with various parts of the device clearly visible. The person's hand is steady, and the movement is smooth, indicating that they are experienced in handling the paper. The background is dark, which contrasts with the white paper and makes the drawing stand out.
