"positivePrompt": "A cinematic wide shot of a lonely lighthouse on jagged black cliffs during a violent nighttime storm. Sheets of rain slash across the frame, waves crash explosively against the rocks, and the lighthouse beam sweeps rhythmically through dense sea mist. A small rescue boat battles the surf and approaches the cove, its lantern flickering in the wind. The camera slowly pushes forward with realistic motion, dramatic lighting, detailed water simulation, atmospheric fog, and natural temporal consistency. Generate synchronized audio with rolling thunder, crashing waves, heavy rain, wind gusts, distant foghorn, creaking boat wood, and shouted dialogue from the boat captain: 'Hold steady! We're almost there!'",

"positivePrompt": "A cinematic neo-noir rooftop scene at night in a rain-soaked futuristic city, vertical composition. A detective in a dark trench coat stands near the ledge under a flickering red neon sign, wet hair, subtle breath in the cold air, distant flying traffic and glowing billboards behind him. Slow push-in camera movement with gentle handheld realism, natural body motion, blinking, coat fluttering in the wind, raindrops streaking across the frame, reflections on concrete. He looks into camera and says in a low, weary voice: \"Every light in this city hides a lie, and tonight they are all speaking at once.\" Layer rich synchronized audio with his clear dialogue, soft rain, distant sirens, humming neon, wind gusts, and faraway traffic. Moody high-contrast lighting, realistic faces, filmic color grading, excellent temporal stability, coherent motion, premium cinematic quality.",

"positivePrompt": "A cinematic futuristic spaceport at blue hour, ultra-detailed, wide establishing shot transitioning into a smooth forward camera glide through a crowded arrival platform. Steam rises from vents, holographic signage flickers in multiple languages, docking lights sweep across polished metal surfaces, and travelers in varied costumes move with natural timing. A silver shuttle descends overhead with believable scale and motion, landing gear deploying as dust and mist swirl outward. In the foreground, a calm female pilot turns toward camera and says, 'Welcome to Orion Gate. Final boarding for the Europa run begins now.' Her speech is naturally synchronized with mouth movement. Layer rich ambient audio: distant engine rumble, intercom chatter, footsteps, rolling cargo carts, hydraulic hiss, soft electronic beeps, and the shuttle touchdown thud. Emphasize temporal stability, realistic crowd motion, coherent reflections, cinematic lighting, high production value, and immersive sound design.",

"positivePrompt": "A cinematic nighttime scene in a rain-soaked neon alley in a futuristic Asian megacity. The camera begins with a slow dolly-in toward two characters standing beneath glowing shop signs and drifting steam. A tired courier in a reflective jacket turns to a detective holding a flickering holographic tablet. The courier says, \"I got the package here. You were followed.\" The detective replies quietly, \"I know. Keep walking and don't look back.\" Their speech is natural and synchronized with lip movement. Surround them with detailed ambient sound: distant hover traffic, soft rainfall hitting puddles, buzzing neon, muffled club bass from behind a metal door, footsteps splashing on wet pavement, and a brief rumble of thunder. The lighting is moody and high-contrast with vivid magenta, cyan, and amber reflections. Motion is realistic and coherent, with subtle head turns, cloth movement, drifting mist, and believable camera parallax. Production-ready cinematic quality.",
