In the video, a person is seen preparing a marinade for a piece of meat. The person pours a dark liquid, which appears to be soy sauce, into a clear plastic bag. Then, they add a spoonful of brown powder, which could be a type of spice or seasoning, and a spoonful of minced garlic. The person then seals the bag and shakes it to mix the ingredients. The video does not show the person's face, and there are no other objects or people visible in the frame. The focus is solely on the preparation of the marinade.
