In the video, a person is seen spreading a white sauce over a pizza crust. The sauce is spread evenly across the surface of the crust, covering it completely. The person uses a spatula to spread the sauce, ensuring that it covers all areas of the crust. The pizza crust appears to be pre-cooked and is placed on a baking sheet. The sauce is thick and creamy, and there are visible chunks of green herbs mixed into it. The person's movements are deliberate and careful, ensuring that the sauce is spread evenly. The video does not show any other ingredients being added to the pizza, so it is unclear what the final product will be.
