【English Prompt】
Generate a 20-second video in a 16:9 aspect ratio. In a natural open field beside a fence, a horse calmly grazes on the grass. After establishing this quiet action, the horse suddenly lifts its head, accelerates, and runs across the field, with the camera smoothly tracking its movement. Use realistic animal motion, consistent daylight, and a clear visual progression from grazing to sudden running. Do not use source video or audio as input.
