Cyclist Chased by Zebra Herd

Create a cinematic, photorealistic 30-second video of a young woman riding a bicycle along a dirt road through a lush green forest. She wears a black baseball cap, a loose blue T-shirt, black shorts, and white sneakers, with long brown hair flowing naturally behind her. She rides confidently with her arms stretched outward before looking back and noticing a large herd of zebras running toward her. She reacts with shock and fear, quickly grips the handlebars, and pedals faster as the zebras charge down the road, raising clouds of dust. Dozens of zebras run around her bicycle, creating an intense and thrilling chase scene. She eventually slows down, looks at her smartphone in disbelief, and raises it to her ear with wide eyes and an open mouth. Use smooth tracking shots, realistic bicycle movement, natural animal motion, detailed zebra stripes, flowing hair, dust particles, and soft daylight. Maintain consistent characters, realistic physics, and natural expressions throughout the video, with no unnatural morphing, no text, and no background music.
