Use the supplied video as the locked source of camera movement, timing, pipe geometry and animation. Use the still reference only for photographic lighting, metal appearance and particle depth. Keep the original video viewpoint and trajectory throughout the shot. The main visual is a very dense stream of extremely fine dry WHITE RAIN travelling forward into the depth of the pipe. Countless tiny opaque off-white specks enter from the near foreground, overtake the camera, shrink with distance and disappear toward the distant vanishing point. The camera follows in the same direction, more slowly. The nearby wall and its existing joints slide backward past the lens, while the white stream rushes ahead. Preserve this clear difference in motion. Make the white stream substantial and continuously supplied across the pipe. Create photographic depth: a few nearby fine streaks are softly out of focus, a limited mid-distance layer is clearly resolved, and the much finer distant particles overlap into dense soft white air that nearly obscures the far wall. Their brightness and spacing vary subtly. Avoid identical sharp marks across the entire picture, oversized snowflakes, screen-space grain, graphic radial speed lines and smoke puffs. The particles occupy three-dimensional air and remain separate from the wall surface. A broad off-camera light from ahead and to the side illuminates the white stream. Sheltered metal is neutral mid-grey, with broad soft reflections and realistic light falloff. Preserve a readable quiet strip of the nearby smooth satin stainless-steel wall, with very fine restrained brushing. No new hatches, windows, doors, panels, rings, bolts or equipment. The existing far rim is open; particles continue through it into depth. It must never become a solid lid or disc. Preserve the original golden filaments and their independent flowing wave motion. Fine foreground white streaks briefly obscure tiny sections of the gold, and adjacent particles catch a delicate warm light. Thin bright cores, controlled bloom and subtle local metal reflections. No changes to the path or timing of the energy. Natural photographic contrast, gentle highlight roll-off, consistent exposure, stable material textures and believable directional motion blur. One continuous shot with the exact original camera animation. Prioritise dense forward-moving white material, spatial depth, simple real metal and light interacting with particles.
