The video shows a person's hands tying a knot with a yellow rope. The rope is threaded through a black carabiner, which is attached to a white piece of paper. The person ties the knot by looping the rope around itself and pulling it tight. The knot is then secured by tying a loop around the carabiner. The person repeats this process several times, each time tying the knot and securing it with the carabiner.
