Video prompt: The room is a creative haven, with canvases leaning against the walls and brushes of various sizes scattered across a nearby table. As she dips her brush into the paint can, the bristles glide smoothly over the wood, transforming the dull surface into a lively hue. Sunlight streams through the large window, casting a warm glow on her focused face and illuminating the tiny specks of dust dancing in the air. In the background, soft jazz music plays from an old record player, adding a rhythmic soundtrack to her artistic endeavor. She pauses occasionally to admire her work, her eyes reflecting the joy of bringing new life to an old piece of furniture.
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)
Explanation: The paintbrush in the person’s hand stretches like a spring and then returns to its original length as it is used, creating an unrealistic effect. The paintbrush should maintain a fixed, rigid shape and not stretch or deform during movement.This spring-like stretching behavior is unnatural, as a paintbrush should retain a consistent length and shape regardless of motion. For realistic representation, the paintbrush should appear stable and unchanging in length as the person uses it.
