Velvet Cold Brew — Iced Coffee Cascade

An 8-second slow cascade film, vertical 9:16, photorealistic. For a velvet cold brew: dark coffee blooming through cold milk over crystal ice spheres in 1000fps, settling into a perfect gradient. 0-3s: the tall glass — crystal-clear ice spheres stacked inside, already cracking with faint ticks as they meet the room's warmth. Dark coffee pours over them in 1000fps, the stream hitting the ice and blooming outward through a layer of cold milk in smoky tendrils, the two liquids marbling in slow, smoky ribbons. 3-6s: the cascade — condensation races down the glass in macro droplets, the coffee's tendrils sinking and swirling. The camera circles the glass as the layers settle into a perfect gradient: dark espresso black at the bottom, fading to milky silk at the top, the ice spheres suspended. 6-8s: the stir — a long spoon slides in and blends the gradient into uniform silk, the whole glass turning to smooth velvet. The camera holds on the finished cold brew, condensation beading, the ice glowing through the silk. Craft: the tall glass; the crystal-clear ice spheres; the dark coffee and cold milk; the long spoon; the macro condensation. Camera: circling the glass, macro on the pour and the condensation; fluid, cool moves. Lighting: cool bright backlight, the gradient glowing, condensation sparkling. Mood: crisp, smooth, refreshing. Style: iced-beverage macro cinematography, photorealistic, 8 seconds, vertical 9:16.
