潛航器駛向光亮

Treat appearance, colors and setting details below as defaults that the user request may replace; keep the timing, actions, subject counts and continuity requirements. Create a 12-second underwater adventure in one continuous tracking shot. One small yellow research submersible with two round side windows travels through a wide canyon lined with softly glowing coral. Keep its hull shape, window count and headlight direction consistent; no person needs to be visible. From 0–4s, the camera follows slightly behind and beside the vessel at a steady distance, revealing bubbles and blue-green light across the rock walls. From 4–9s, a very large indistinct animal shadow crosses a distant opening behind the submersible, remaining separated from it by clear water. The vessel makes one smooth upward bank toward a brighter gap, and the camera follows the same readable curve. From 9–12s, both emerge into open water beneath broad sunbeams; the shadow remains below and disappears into darkness. Hold the vessel against the light as it continues safely forward. Audio: muted thruster hum, soft sonar ticks and underwater rumble. No impact, rapid camera spins, ruins, shipwrecks, captions or logos. User request: A yellow research submersible leaves a glowing canyon through a sunlit gap while a distant animal shadow remains below.
