In the video, a man is standing in front of a whiteboard, pointing to it with a marker. He is wearing a white lab coat and glasses. Behind him, there are three other people also wearing white lab coats. They are all standing in a room with a gray floor and walls. The man appears to be explaining something to the others, who are attentively listening. The whiteboard is blank, and there are no visible texts or drawings on it. The lighting in the room is bright, and there are no other objects or furniture visible in the background.
