Slide video – prompt

Generate a hyper-realistic, continuous first-person POV vertical video (9:16 aspect ratio) lasting approximately 65 seconds. The viewer embodies a person sliding down a steep, bright red fiberglass water slide attached to the side of a massive, sheer brown rock cliff overlooking a deep blue ocean.
Visuals & Character: Only the rider’s bare legs, feet, and occasional hands are visible in the lower frame. The rider wears black swim trunks. Skin is realistic, wet, with natural leg hair. Hands grip the raised edges of the red slide. Water flows rapidly beneath the body, creating constant splashes around the legs. The camera uses a wide-angle action-lens perspective with deep depth of field.
Sequence – Part 1 (The Descent): Start at the top of the slide. Directly below in the churning ocean waits a colossal, terrifying sea monster with a massive circular maw lined with jagged white teeth and long tentacles radiating outward. The rider pushes off. Accelerate rapidly down the winding slide, hugging the cliff face on the right. Apply heavy directional motion blur to the passing rocks and ocean to convey extreme speed. The camera shakes intensely with the velocity. The slide curves left and right, but the monster’s gaping mouth remains the central focal point, growing larger and more detailed as the rider approaches. Sunlight glints brightly off the ocean waves and the wet red slide.
Sequence – Part 2 (The Maw): As the rider nears the bottom, the monster’s mouth fills the lower half of the frame, appearing as a dark tunnel entrance surrounded by rows of enormous, sharp teeth. Mist rises from the creature. At exactly the 43-second mark, the rider plunges seamlessly into the monster’s mouth. The bright sky and ocean are instantly replaced by the dark, cavernous interior of the throat. Massive teeth pass closely on the left and right without touching the rider. The red slide continues uninterrupted into the darkness.
Sequence – Part 3 (The Throat & Cave): Inside the throat, the environment is a dark, cylindrical tunnel with organic, rocky-textured walls. A secondary ring of spikes is visible further down. A faint blue light glows ahead. The slide descends through this gullet. Around the 52-second mark, the tunnel opens into a vast, breathtaking underwater cave system. Volumetric shafts of sunlight pierce through holes in the rocky ceiling, illuminating the clear turquoise water and rugged dark stone walls. The lighting shifts from harsh daylight to dark shadow, then to ethereal, glowing cave illumination. The rider continues sliding smoothly deeper into this sunlit subterranean passage until the video ends.
Audio Profile: Sync loud rushing wind and water sounds with the high-speed descent. Include a low, ominous rumble from the monster. Upon entering the mouth, muffle the external noise and add a wet, echoing tunnel resonance. In the cave, transition to peaceful, reverberant water drips and an ambient underwater drone. No dialogue. No music cuts.
Physics & Continuity: Maintain strict continuity of the rider’s legs, black shorts, and the red slide’s dimensions. Ensure realistic gravity-driven acceleration. Water must splash logically against the body. The monster’s scale must remain consistently gigantic. No cuts, no morphing, no extra limbs, no text, no watermarks. The experience must feel like a terrifying, immersive, single-take thrill ride.
