The video shows two men in a martial arts dojo. One man is wearing a white gi, and the other is wearing a blue gi. The man in the white gi is demonstrating a technique on the man in the blue gi. He starts by sitting on the man's leg, then moves to the man's back, and finally, he flips the man over onto his back. The man in the white gi then pins the man in the blue gi to the ground. The technique appears to be a combination of a triangle choke and a back mount.
