Kling 2.5 Turbo (pro) Vertical video 9:16, 6 seconds, top-down drone shot (90°). Camera flies forward smoothly and fast along a narrow canyon riverbed, slight drone micro-shake, subtle motion blur. Artistic realism, cinematic natural lighting, high detail, nature documentary look. Below: deep empty rock dams/barriers made of mountain stone (layered cliffs, boulders, jagged ridges), no man-made materials, no people. A powerful river bursts through tight cracks/gaps in the rock dams, slams into the stone walls, creating huge splashes, white foam, volumetric water mist, turbulent eddies. Then the flow widens suddenly and rapidly spreads over both banks downstream, rushing over rocks and sandy shallows, leaving dark wet surfaces. Timing beats: 0–2s: approach and pass over first rock dam, show depth and narrow breakthrough. 2–4s: directly above impact zone, maximum spray and mist. 4–6s: fly over widening floodplain, water fanning out across banks. Negative prompt: concrete, metal, buildings, machinery, people, animals, text, logos, cartoon/anime, fantasy, plastic look, unrealistic water physics, heavy distortion/warping, flicker, low-res, oversharpening.
