Video prompt: A breeze carries clouds of factory smoke across a meadow. As the polluted air meets the cleaner air over the meadow, observe the gradual diffusion and blending of the two, while flowers in the meadow sway in response to the changing wind currents, subtly reacting to the air quality.
Defect: Blurring (abnormal blur, e.g. one bird of a group blurs)
Explanation: This part of the video is overly blurry, yet there appears to be a butterfly shape that isn’t clearly defined, causing a noticeable flickering effect.
