Grok Imagine 巨型机甲踏过铁轨 电影写实提示词

Cinematic 10-second vertical 9:16 or horizontal 16:9 video, ultra-realistic photorealistic style, masterpiece, best quality, 8K.\n\nA colossal 40-meter-tall industrial military bipedal mecha walker named "S-9000" slowly walks forward with heavy, powerful steps on old wet train tracks in a foggy European city square. The giant mech has a weathered orange-and-dark-gray color scheme with heavy rust, battle damage, exposed pipes, cables, hydraulic lines, rivets, warning labels, and glowing yellow cockpit lights. Its upper body is a massive armored command module with antennas and satellite dishes. Its legs are enormous, heavily articulated with multiple huge black off-road tires with bright orange rims and thick treads.\n\nIn the foreground, a lone soldier in full black tactical gear, helmet, backpack and rifle stands motionless on the tracks with his back to camera, looking up in awe at the towering machine. Dramatic low-angle camera shot that emphasizes the insane scale difference between the tiny human and the gigantic mech.\n\nAtmosphere is thick, cold, misty/foggy, overcast sky, soft diffused cinematic lighting, subtle god rays, volumetric fog, slight motion blur on moving mechanical parts, realistic physics on every joint and piston. The mech takes slow, deliberate steps — right leg lifts and plants, then left leg, heavy body shifts and sways, arms swing slightly for balance, pistons hiss and steam vents.\n\nHighly detailed textures, intricate mechanical details, realistic metal reflections, cinematic color grading, moody and epic sci-fi atmosphere, in the style of concept art by Jakub Rozalski and Syd Mead, photorealistic rendering, 8K, ultra-detailed, masterpiece.
