Video 1: Ocean Megacity Flight 15-second cinematic video, no reference images. A futuristic ocean skyscraper city built above the sea, with tall glass towers rising from artificial islands, bridges over the water, sunlight reflecting on waves, vertical gardens, and clean white-blue architecture. The camera begins from a very high bird’s-eye view above the ocean, showing the entire floating city surrounded by shimmering water. The camera dives rapidly from above into the skyscraper district like a fast bird, not a machine. It rushes down between ocean-facing towers, glides past reflective glass walls, banks around a rooftop garden, cuts through a narrow gap between two skyscrapers, then flies low above a water canal before rising sharply back into the skyline. The movement should be highly dynamic and immersive: steep dives from above, fast side passes along towers, sudden upward climbs, wide ocean reveals, close passes near bridges and rooftops, and quick turns through deep city canyons. The main attraction is the feeling of flying through a vertical city surrounded by the sea. At the end, the camera climbs above the tallest tower and reveals the entire ocean megacity glowing in sunlight, with waves far below. No visible drone, no aircraft, no helicopter, no cockpit. The camera feels like the eyes of a bird flying freely through the skyscrapers. No background music. Sound effects only: rushing wind, distant ocean waves, city ambience, bridge echoes, air pressure whooshes.
