Video prompt: The kitchen is alive with the sound of a radio playing soft jazz in the background. As the knife glides through the onion, the person expertly gathers the pieces and gently adds them into a hot, cast-iron skillet. The onions hit the pan with a satisfying sizzle, releasing a fragrant steam that fills the air. The person stirs the onions with a wooden spoon, watching them turn translucent and begin to caramelize, their edges browning to perfection. Sunlight streams through the window, casting a warm glow over the scene, as the person hums along to the music, fully immersed in the joy of cooking.
Defect: Deformation (when Object is involved in an act,  anything in this process that's weird. e.g. people walk into a wall. "Walk" is an act)
