Create a 10-12 second cinematic underwater wildlife video in a deep ocean trench. Begin with an ultra-wide drifting shot of one enormous whale moving slowly through dark blue water, its full body readable against faint shafts of light. Push in smoothly to show skin texture, pale barnacles, and small silver bubbles streaming along the body. Glide beside the whale as one calm eye and a broad pectoral fin pass the camera. A second whale rises from the background and joins the first in a slow parallel formation. End with both whales diving together, tail flukes moving downward and sending a controlled cloud of bubbles across the lens before the frame settles back into blue quiet. Keep the tone majestic, peaceful, and natural. Avoid monster framing, attacks, blood, distressed animals, boats, divers in danger, excessive turbulence, impossible scale shifts, unreadable darkness, harsh camera shake, or bubbles that hide the whales for too long.
