The short prompt, expanded into a shot description (look, camera, timeline, sound) before rendering.

Cinematic nature documentary look, shot on a long telephoto lens with deep contrast, glowing orange and black palette, moody and awe-inspiring. A dark volcanic coastline at night, black basalt cliffs jutting into a restless ocean under a starless sky. A glowing river of molten lava pours down the rocky slope and spills over the edge into the water. Where the lava meets the sea, thick white and grey steam bursts upward in violent plumes, lit orange from beneath. Wisps of ash drift through the air, and faint sea spray catches the glow along the shoreline. Camera: Wide static shot framing the entire coastline in 16:9, with a slow, subtle push-in toward the lava entry point. Timeline: [0s-2s] Lava pours steadily down the dark cliff face, the ocean glowing faintly beneath it. [2s-3.5s] The lava hits the water and a massive plume of steam erupts upward, illuminated orange. [3.5s-5s] The steam billows and spreads across the night sky as the lava keeps flowing and sparks drift on the wind. Audio: Deep rumbling of the volcano, crackling and hissing of molten rock meeting water, rolling ocean waves against the rocks, and a roaring whoosh as the steam erupts. Realistic physics and natural motion, consistent scene throughout, no text or subtitles.
