Voyage cinématographique dans le temps vers 2050

A cinematic 15-second ultra-realistic sci-fi sequence. The video opens in 2025 with a close-up of a confused time traveler standing in a dark alley wearing a worn coat, holding a glowing broken time device in his hand. The device suddenly activates, emitting a bright blue-white energy pulse. The environment distorts as reality bends and collapses into light. A dramatic transition occurs as he is violently pulled through a wormhole of swirling neon particles, floating debris, and fragmented timelines. Cut to silence and then a breathtaking reveal: the traveler lands in 2050. A massive futuristic megacity stretches infinitely into the sky with glowing vertical skyscrapers, flying vehicles, holographic advertisements, and floating transit bridges between towers. The atmosphere is clean, slightly foggy with glowing neon reflections everywhere. Camera slowly tilts upward from street level as the traveler looks around in shock. People with advanced cybernetic enhancements walk past him, drones scan the air, and holographic signs flicker in unknown languages. Final shot: wide cinematic skyline of the futuristic city with sunset blending into neon night, massive holographic moon in the sky, and the time traveler standing alone in awe. Style: ultra-realistic, cinematic lighting, high detail, 4K, dramatic atmosphere, shallow depth of field, handheld cinematic motion, emotional sci-fi tone.
