SEEDANCE 15s — 9:16 — STORYBOARD-LOCKED PROMPTCreate a 15-second, 9:16 vertical, photorealistic cinematic VFX sequence inside a realistic 34 St New York City subway station. One continuous hyper-fast FPV shot, no cuts.The camera behaves as though a GoPro is attached to the front/top of the dark-matter entity itself. The viewer travels with the creature. Its camera motion floats 1–2 metres above the ground, rapidly gliding, dipping, rising and swaying from side to side while searching for a host — similar to the searching motion of a long flexible neck, but do not make the entity literally shaped like an animal or snake.The creature is a single cohesive black charcoal-tar liquid organism, extremely high viscosity, dense, heavy, glossy and self-bonded. It can stretch and deform while moving, but always remains connected to itself. No watery splashes, no scattered droplets, no nanobots, no metal, no robotic components.Use [image1]0:00–0:02 — PANIC ON PLATFORM:Creature-mounted FPV camera rushes through the 34 St subway platform. Diverse American/New York commuters run in terror. The cohesive black mass is visible beneath and around the camera as it rapidly approaches them. Strong wide-angle GoPro perspective, speed blur and frantic movement.0:02–0:04 — HOST-SEEKING GLIDE:The camera rises slightly and floats through the station with an unnatural searching movement, dipping left, sweeping right, then locking onto a fleeing businessman. The attached black mass stretches smoothly through the air and along nearby surfaces while staying completely bonded together.0:04–0:06 — FIRST ABSORPTION:Rapidly accelerate toward the businessman. The cohesive tar mass flows around him from several directions and completely engulfs him inside its opaque black body. No gore or visible injury. He simply disappears inside the dense living mass. The entity becomes slightly larger.0:06–0:08 — CAMERA HUNTS NEXT HOST:Do not stop. The creature-mounted camera immediately whips away from the first target and glides rapidly through the fleeing crowd. It floats, searches left and right, then notices a frightened woman looking back while running. The camera changes direction toward her.0:08–0:10 — SECOND ABSORPTION:The entity rapidly closes the distance. The high-viscosity black mass expands around the woman and completely absorbs her into the same connected opaque organism. No blood, no gore. The mass becomes larger again and immediately continues forward.0:10–0:12 — SMASH THROUGH:Without cutting, the enlarged entity surges forward and crashes through a tiled concrete subway pillar and illuminated advertising display. Concrete fragments, sparks, dust and glass fly outward, while the black organism itself remains completely cohesive and connected.0:12–0:14 — FINAL IMPACT:Camera and entity accelerate toward the far concrete wall. The mass violently drives through it, opening a large circular breach into the subway tunnel. Heavy concrete rubble and dust blast outward while the creature remains one continuous bonded form.0:14–0:15 — INTO THE TUNNEL:The camera dives through the new opening together with the entity. The cohesive black mass glides rapidly down the dark railway tunnel toward red signal lights and disappears into darkness.VISUAL / CAMERA RULES: photorealistic live-action VFX, GoPro Hero 12 ultra-wide appearance, creature-mounted FPV, aggressive speed, rapid floating movement, neck-like searching camera behaviour, strong but readable motion blur, realistic New York subway architecture, MTA-style 34 St / Downtown / Uptown / Exit signage, diverse American commuters, flickering fluorescent lights, reflections, dust, sparks, realistic destruction, one continuous shot.CRITICAL: The black substance must never become water, flying droplets, separate tentacles, nanobots or metallic material. It is one bonded ultra-viscous charcoal-black tar organism throughout the entire sequence.
