"Create a dynamic product advertisement video for a modern, minimalist black backpack with a bold orange 'BETA' text overlay. The video should feature smooth, high-tech transitions, close-up shots highlighting material quality, zippers, compartments, and water resistance. Use clean white and gray backgrounds with subtle light reflections, emphasizing a premium, tech-savvy urban lifestyle. Include slow-motion clips of the backpack in motion, being worn by professionals in modern city environments. The overall aesthetic is sleek, sophisticated, and cutting-edge."
