In the video, a man is seen standing next to a river. He is holding a rock in his hand and appears to be examining it closely. The man then proceeds to use a knife to cut into the rock. It is unclear what he is trying to do or what he is looking for, but he seems to be focused on his task. The river is flowing gently in the background, and the man is wearing a white shirt and a hat. The lighting suggests that it is daytime, and there are no other people or objects visible in the frame.
