In the video, a person's hand is seen turning a dial on a machine. As the dial turns, the numbers on a digital display above it change. The display starts at 123 and goes up to 200. The hand turns the dial several times, and each time the number on the display increases by 10. The machine appears to be some kind of control panel, and the dial seems to be used to adjust the settings. The numbers on the display are bright and clearly visible, and the hand turns the dial smoothly and deliberately.
