The video shows a close-up of a pan with diced onions being sautéed. The onions are being stirred with a wooden spatula. The pan appears to be on a stovetop, and the onions are taking on a golden brown color as they cook. The spatula is being moved in a circular motion to ensure even cooking. The onions are sizzling in the pan, indicating that they are being cooked at a high temperature. The video does not show any other ingredients being added to the pan, so it is likely that the onions are being sautéed as a base for a dish.
