In the video, a person is seen using a brush to apply a sauce onto a piece of meat that is placed on a wire rack. The sauce appears to be a dark, thick liquid, possibly barbecue sauce. The person brushes the sauce onto the meat in a circular motion, ensuring that it is evenly coated. The meat is then placed into an oven to cook. The oven is not visible in the video, but the person's hand is seen placing the rack into the oven. The video ends with the meat being cooked in the oven.
