"positivePrompt": "Extend the provided video seamlessly. Continue the slow forward camera movement as the cargo airship nears a narrow gap between colossal sandstone spires high above a cloud layer. A mechanic in a patched amber flight coat steps carefully onto the outer rigging and secures a snapping cable while fabric sails strain in the wind. The ship creaks, metal rings vibrate, loose tools rattle, and distant birds circle below. As the cable is fastened, the vessel stabilizes and glides through the gap, revealing a vast aerial caravan route with several far-off balloon craft crossing the horizon. Preserve continuity with the original clip's lighting, lens feel, weathered textures, and motion. Emphasize cinematic realism, expressive environmental sound, layered depth, and smooth continuation rather than a cut to a different scene.",

"positivePrompt": "A sweeping cinematic dive through the flooded remains of an ancient grand library beneath clear turquoise water. Towering stone shelves lean at odd angles, thousands of swollen books drift slowly upward, marble busts are wrapped in waving seagrass, and shafts of sunlight ripple through a cracked glass dome overhead. A school of silver fish parts as the camera glides forward between columns carved with faded maps and constellations. Loose pages spin in the current, a brass globe rests half buried in sand, and tiny air bubbles trail past the lens. Midway through the shot, a giant sea turtle crosses the hall, stirring sediment into glowing golden haze. End on a wide reveal of the entire submerged archive with broken staircases, collapsed balconies, and distant whale-song ambience. Natural underwater acoustics, creaking stone, soft currents, rustling paper, graceful cinematic realism, high detail, volumetric light, atmospheric depth.",

"positivePrompt": "Using the provided first-frame image as the opening shot, create a cinematic sequence across a reflective salt flat at sunrise. The caravan advances slowly toward camera-left while ripples spread through the thin water layer, banners flutter in gusts, dangling metal charms clink softly, and the animals leave delicate wakes in the mirrored surface. One traveler adjusts a scarf, another turns to look toward distant crystal outcrops catching the early light. The camera begins low and gliding, then eases into a gentle lateral tracking move that emphasizes reflections and scale. Atmosphere is serene, expansive, and slightly otherworldly, with realistic motion, natural fabric physics, subtle dust and mist, shimmering heat distortion, and rich environmental detail. Include synchronized ambient audio: soft wind, hoof splashes, harness creaks, faint chimes, no dialogue, no subtitles.",

"positivePrompt": "Starting from the provided first frame, create a cinematic 8-second shot of a cliffside falconer camp above a restless ocean at golden hour. The camera makes a slow forward drift with slight lateral movement. The falconer remains the focal subject while the bird blinks, shifts its weight, ruffles feathers, and briefly spreads one wing against the wind. Canvas tents tug and ripple, ribbons whip sharply, grass bends in gusts, smoke trails from a fire, and pack animals make subtle natural movements in the background. Far below, waves crash against rock faces with visible spray. Preserve grounded realism, tactile fabrics, weathered gear, believable anatomy, and cohesive lighting. Emphasize sweeping atmosphere, layered depth, and documentary-style cinematic detail. Generate synchronized audio with wind gusts, cloth flapping, distant surf, soft camp creaks, and occasional falcon chirps.",
