In the video, we see a close-up shot of a pan on a stove where diced onions are being sautéed. The onions are white and have a translucent appearance, indicating that they are being cooked. A wooden spoon is being used to stir the onions, ensuring even cooking. The pan appears to be non-stick, and the stove is lit with a blue flame, suggesting that the heat is set to medium. The background is blurred, but we can see that the kitchen is well-lit, and there are other cooking utensils visible. The sound of sizzling can be heard, which is typical when cooking onions. 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.
