    "prompt": "Create a polished twelve-second nature trailer using these three reference photographs in this exact order. @Image1 is the mountain lake: seconds 0-4, a calm wide establishing shot with very gentle water ripples and a subtle slow push forward. Hard cut. @Image2 is the aerial boreal forest and lakes: seconds 4-8, a slow smooth forward aerial drift, preserving the green forest and winding water. Hard cut. @Image3 is the bison cow and calf: seconds 8-12, an intimate calm wildlife closing shot with subtle natural breathing, the calf stays beside its mother. Preserve the recognizable subjects and colors of each reference; do not blend the three locations or morph one photograph into another. Photorealistic, restrained movement, natural daylight. Silent video, no music, no speech or sound. No titles, no logos, no text, no extra animals or people. Finish on the bison pair.",
