Prompt de Erupção Vulcânica em Cidade Miniatura com Efeitos Visuais Cinematográficos

12 seconds, 9:16 vertical, 24fps, hyper-realistic film VFX behind-the-scenes, phone ultra-wide handheld one-take. Inside a massive VFX studio, a high-precision miniature model of Pompeii fills the foreground - gray-white stone streets, ochre terracotta roofs, Roman temple colonnades, cypress trees, a semicircular amphitheater, and dense miniature figures; the central avenue leads to a model of Mount Vesuvius. Blue screens with red tracking crosses, overhead lighting trusses, cold white LED studio lights, suspended cameras, model platforms, cables, and crew in black "EFFECTS CREW" T-shirts. The shot starts behind crew and a large film camera, smoothly pans right and pushes forward continuously, then moves past the crew to form a central-axis composition along the ancient city avenue. At 1.5 seconds, the volcano crater glows orange, a white-hot orange-red column of fire shoots skyward, sparks radiate outward, quickly forming a thick dark-gray cauliflower-shaped smoke column; a low-altitude light-gray pyroclastic flow rushes from the mountain base toward the city at high speed. At 4.5 seconds, a crew member crosses from the right foreground to the left. After 6 seconds, buildings catch fire point by point; at 7.5 seconds, an orange-yellow fireball bursts in the plaza, and a cameraman on the right lifts his camera to follow. After 8.3 seconds, the pyroclastic flow engulfs the ancient city and surges toward the lens; at 10 seconds, thick smoke completely blocks the frame, with studio lights glowing through the haze; finally, a black-clad cameraman with a shoulder-mounted camera emerges from the dense smoke on the right, moves left, and is swallowed by smoke again. Real physical miniature sets, practical pyrotechnics, gravity-driven sparks, continuous turbulent volumetric smoke, cold blue studio lighting contrasted with warm orange firelight, deep depth of field, slight handheld sway, high temporal consistency, no cuts.
