Create a 30-second, 1080p ultra-realistic cinematic commercial for a fictional premium smartwatch brand called VANTA. The film should feel like a high-end global technology and sports campaign, showing the watch performing across completely different environments. A stylish young woman with long dark hair wears the same VANTA smartwatch throughout the film. Keep the watch design, color, proportions and display consistent. Opening — City: She walks through a modern city wearing a black fitted athletic top, charcoal leggings and running shoes. The watch display shows heart rate and activity tracking as she starts running. Swimming: Cut seamlessly to her in a swimming pool wearing a sleek black athletic swimsuit. Underwater shots show her swimming while the smartwatch remains clearly visible, tracking her workout. Rain: She emerges outdoors wearing a black waterproof running jacket, black leggings and running shoes as heavy rain begins. She continues running through wet streets while water runs across the watch. Show a close-up of the display remaining active. Mountain: Transition to a mountain trail. She wears a dark green performance jacket, black hiking leggings and trail shoes. She climbs while the watch displays heart rate, distance and elevation. Gym: She is now wearing a dark sports bra, black leggings and training shoes, performing strength exercises. Brief close-ups show workout tracking and heart-rate data. Final — Sunset: She stands on a rooftop wearing a minimal black athletic jacket and leggings, watching the sunset. The camera moves from her face to the smartwatch for a detailed hero close-up. Voiceover throughout: "Built for every environment. Track your heart rate, your workouts, your progress and every step forward. From the pool to the pavement, from rain to the highest trail—VANTA keeps up with you. One watch. Every move." Style: Photorealistic, cinematic sports cinematography, realistic water and rain physics, detailed smartwatch materials, dynamic tracking shots, macro product shots, natural movement, dramatic lighting, shallow depth of field and premium technology advertising. Negative: No watch design changes, inconsistent display, identity drift, outfit glitches, distorted hands, extra limbs, duplicated people, fake-looking water, excessive CGI, random text, subtitles or watermark.
