In the video, a person is seen writing on a blackboard with chalk. The person is writing the numbers "6180966" in a continuous line. The blackboard is dark in color, and the chalk is white, creating a stark contrast. The person's hand is steady as they write, and the numbers are written in a neat, legible manner. The blackboard is positioned against a wall, and there is a light source shining on it, making the numbers stand out even more. The video is shot from a close-up angle, focusing on the person's hand and the blackboard.
