Grok Imagine 巨型机甲踏碎城市 赛博朋克科幻提示词

Cinematic photorealistic 6-second video, ultra-detailed 8K, shot on IMAX 70mm. A colossal 200-meter-tall military mecha, heavily armored in weathered gunmetal gray with orange and blue accent panels, slowly stomps forward through a sprawling coastal megacity. The camera starts at a dramatic low-angle aerial tracking shot, circling around the giant robot as its enormous right foot descends with terrifying force. Massive shockwaves erupt on impact — concrete skyscrapers shatter like glass, explosions of dust, debris, and fire bloom violently upward in slow-motion. Thick clouds of smoke and pulverized concrete billow around the robot’s legs. Its powerful hydraulic joints hiss and glow with heat as it takes another earth-shaking step. The robot’s upper torso and head remain imposing and steady, antennae and weapon systems visible against the bright blue sky. Golden hour sunlight creates dramatic god rays through the dust clouds, lens flares, and volumetric lighting. Tiny fighter jets streak past in the distance for scale. Hyper-realistic physics, intricate mechanical details, cinematic color grading, intense atmosphere, epic scale, National Geographic-level realism, shot on ARRI Alexa 65 + anamorphic lenses, subtle film grain, 24fps.
