[Style] Top natural documentary cinematography, cinematic natural light, high frame rate slow motion. [Scene] High altitude mountains before sunset, snow peaks emerging from thick cloud seas, sky in gold/orange/blue-grey gradient. Sunlight forming volumetric light. Gigantic red and white koi swimming inside clouds. [Shot 1: 00:00-02.5] Vertical Aerial Establishing Shot: Camera rises behind a snow peak. A massive silhouette moves deep in the clouds, pushing up the cloud surface. [Shot 2: 02.5-05.2] High-Speed Telephoto Tracking: A multi-kilometer giant koi leaps out of the clouds. 240fps slow motion captures gill opening, pectoral fin swaying, and water droplets in backlighting. Movement must follow fish biomechanics. [Shot 3: 05.2-07.8] Extreme Wildlife Close-Up: Close-up of head. Amber eye reflecting sunset and mountains. Focus shifts to scales with growth lines and pearl textures. Gills rising with breath. [Shot 4: 07.8-10.0] Low-Angle Wide Tracking Shot: Following the koi toward the sky. Tail fin sweeps the clouds, creating a vortex and dispersing ice crystals. Final frame: tail fin disappearing into golden clouds. [Vertical Composition] Emphasize vertical layers: Mountain-Cloud-Koi-Sky. [Photography] High altitude natural light, sunset backlighting, realistic cloud density and flow. [Sound] Mountain wind, low-frequency vibrations like whale songs, heavy cloud-breaking sounds, subtle scale friction. [Negative Prompts] Cartoon, anime, game CG, plastic fish, dragon movements, wings, snake body, flickering, no cloud interaction, low res, watermark.
