The video shows a large group of people sitting in a dark room. They are all clapping their hands together in unison. The people are dressed in various colors, but most are wearing dark clothing. The room is dimly lit, with some light coming from the front of the room. The people are all facing the same direction, suggesting that they are watching something or someone in front of them. The clapping is rhythmic and continuous, indicating that the people are responding to something they are watching or listening to.
