    "prompt": "A cinematic high-speed tracking shot following a sleek silver drone as it weaves through a bioluminescent forest at night. Glowing neon spores drift in the air, swirling and reacting realistically to the drone's wind wake. The drone's thrusters emit a soft cyan glow, illuminating the vibrant purple flora and mossy ground. High-fidelity motion, stable cinematic lighting, and sharp textures throughout. Audio: High-pitched mechanical hum of the drone, soft rustling of leaves, and ethereal synth-ambient music.",
