"positivePrompt": "Using the provided frame image as the visual anchor, create a sweeping cinematic sequence of a solitary violinist performing on a rugged seaside cliff. The camera begins close on the musician's hands and bow, then slowly arcs outward to reveal the vast turbulent ocean below. Strong coastal wind drives the coat tails and hair sideways, grasses bend in waves, seabirds wheel through the distance, and white spray rises from rocks beneath the cliff. The performance feels emotionally triumphant after a storm, with realistic body motion, natural cloth simulation, layered depth, detailed cloud movement, and rich atmospheric perspective. Preserve the subject identity and costume from @frame while adding elegant motion, dramatic scale, and polished filmic realism.",

"positivePrompt": "Create a cinematic nighttime sequence inside a vast natural history museum. Begin with the atmosphere and composition of @image1: a quiet grand gallery with polished floors, towering fossil exhibits, and dim amber lighting. Transition into the closer, more suspenseful framing and skeletal detail of @image2, emphasizing the rib cage, skull, drifting dust, and tightening tension. Evolve the scene using @image3 as a pivotal transformation moment, where the fossil structure seems to awaken, display cases fracture, particles rise, and the skeleton lifts with uncanny presence. Resolve in the scale and intensity of @image4, with the fully awakened dinosaur skeleton dominating the hall amid debris, sparks, and dramatic contrast. Smooth camera movement, rich environmental detail, realistic lighting, museum ambience, escalating wonder and dread, cohesive progression across all four image references, high-end feature-film look.",
