The video shows a person preparing a boneless rib roast for cooking. The roast is placed on a wooden cutting board, and the person uses a knife to spread a white, creamy substance, presumably a marinade or seasoning, over the surface of the meat. The roast is a large, rectangular piece of meat with a pinkish-red color and visible marbling of fat. The person's hands are visible as they work on the roast, and the knife is used with precision to ensure even coverage of the marinade.
