In the video, a man is seen standing in front of a chalkboard. He is wearing a plaid shirt and has a mustache. He is holding a purple marker in his hand and is using it to write on the chalkboard. The man appears to be speaking and gesturing as he writes. The chalkboard is blank except for the writing that the man is doing. The man seems to be focused on his task and is not looking at the camera. The background of the video is a plain white wall, and there is no one else visible in the frame.
