马匹吃草后绕圈小跑

生成一段20秒、16:9画幅的视频。在日光稳定的自然草地上，开头马匹低头平静吃草。随后马匹突然抬头，清晰地转入小跑，并在草地上沿平滑的圆形路线持续绕圈小跑。让马匹始终完整可见，保持稳定的身体结构、连贯的四肢运动、真实的草地互动和连续的时间一致性。使用稳定的中远景镜头，清楚呈现吃草动作以及完整的绕圈小跑过程。采用自然色彩和写实运动，不要文字、标志、剪辑或依赖音频才能理解的事件。

【English Prompt】
Generate a 20-second video in a 16:9 aspect ratio. In a natural grassy meadow under consistent daylight, a horse calmly grazes with its head lowered during the opening moments. It then suddenly lifts its head, transitions clearly into a trot, and trots in a smooth circular path around the meadow. Keep the horse fully visible, with stable anatomy, coherent leg motion, realistic grass interaction, and continuous temporal continuity. Use a steady medium-wide camera view that clearly shows both the grazing action and the complete circular trotting movement. Natural colors, realistic motion, and no text, logos, cuts, or audio-dependent events.
