{
    "prompt": "Visual: A cyberpunk street at night during a heavy rainstorm; neon signs create flowing reflections on the water-cluttered pavement. A close-up shot focuses on a man wearing a translucent raincoat. Motion: Raindrops collide with the raincoat and slide down; the man slowly looks up, his pupils clearly reflecting the flickering neon lights across the street. He speaks, with facial muscles moving naturally and breath creating a faint mist in the cold air. Dialogue (Voice 1): \"This city never sleeps, and neither do the secrets hidden in its shadows.\" SFX (Sync): Pattering rain, distant car horns, the crisp sound of rain hitting plastic, and deep, resonant vocal dialogue. ",
    "negativePrompt": "Flickering, blur, plastic skin texture, distorted fingers, watermark, low contrast.",
    "duration": "5",
    "aspectRatio": "16:9",
    "cfgScale": 0.5,
    "sound": true,
    "multiShot": false,
