"Cinematic documentary-style underwater shot, fixed static camera, side view at deep ocean floor level, 16:9 aspect ratio, 8 seconds duration. A massive dark grey military submarine glides slowly and smoothly from left to right across the frame at constant speed, moving through the mid-water column above a rocky seabed. Volumetric light beams from above remain constant, fine suspended particles drift naturally in the water. Visible propeller wake and turbulence trail behind the submarine as it moves. No camera movement, locked static shot. Deep blue-teal color grading, photorealistic hull detail, ultra-realistic, 8K, slow continuous linear motion, documentary cinematography style similar to BBC/Discovery deep-sea specials."
