In the video, a person is seen using a knife to cut a piece of string. The string is red and appears to be made of a thin, flexible material. The person's hand is visible, holding the string in place while the knife cuts through it. The background is blurred, but it appears to be a carpeted floor. The knife is silver with a black handle and a sharp blade. The person's hand is steady as they make the cut, and the string is cut cleanly without any fraying.
