The video shows a man walking on a stage in front of a large screen. The screen displays a presentation with a title and some icons. The man is wearing a black and red shirt and black pants. He is speaking into a microphone and gesturing with his hands as he walks. The audience is seated in front of the stage, watching the presentation. The stage has a large sign with the words \"TEDx\" on it. The lighting is dim, and the focus is on the man and the screen.
