The video shows two individuals in a martial arts dojo. One person is wearing a black gi, while the other is wearing a white gi. The person in the white gi is lying on the ground, and the person in the black gi is standing over them. The person in the black gi is demonstrating a technique on the person in the white gi, who is holding their leg. The person in the black gi is using their hands to apply pressure to the leg of the person in the white gi, who is trying to resist the technique. The dojo has a gray mat, and there is a logo on the wall that reads "OSLabs".
