The video shows a man in a white shirt writing on a whiteboard with a blue marker. He is standing in front of a blue curtain. The man is holding the marker in his right hand and appears to be writing or drawing something on the board. The whiteboard is clean and there are no visible marks or writing on it. The man's posture suggests that he is focused on his task and is possibly explaining or demonstrating something. The blue curtain in the background provides a contrast to the whiteboard and the man's white shirt. The lighting in the room is bright, and the man's shadow is cast on the whiteboard.
