Video prompt: A city symphony concert in an open-air amphitheater, musicians playing an arrangement that sweeps the audience into the embrace of timeless compositions under a clear night sky.
Defect: Blurring (abnormal blur, e.g. one bird of a group blurs)
Explanation: The orchestra on stage undergoes strange blurring and shape deformations, creating an unrealistic effect. The blurring reduces visual clarity, making it difficult to distinguish individual members and instruments, while the deformations cause unnatural shifts in their shapes and proportions.
