Use both uploaded underwater photos as strict visual references. Reference priority: - Image 1 = primary identity reference for the man’s face, body, hair, white swim shorts, cake design, and overall underwater look. - Image 2 = action reference for the blowing expression and the position of the cake closer to the face. FORMAT: 8 seconds, vertical 9:16, photorealistic live-action underwater video, one continuous shot, no cuts, no transitions, no scene changes. CORE GOAL: Create an extremely realistic underwater birthday video in the open ocean. The result must look like authentic live footage shot with a real underwater camera, not AI-generated. The main priority is preserving the exact identity of the man from the references and making the underwater action believable. IDENTITY LOCK: The man must remain the same person throughout the entire video: - same face - same facial proportions - same nose - same jawline - same mouth - same eyebrows - same eye area - same medium-long dark wet hair - same athletic build - same skin tone - same white swim shorts Do not change his identity. Do not make his hair shorter. Do not change his hairstyle. Do not replace him with another generic man. ENVIRONMENT: This scene takes place underwater in the open ocean, not in a swimming pool. Very important: Do NOT show a pool. Do NOT show pool tiles. Do NOT show pool walls. Do NOT show pool floor patterns. Do NOT show pool steps. Do NOT show pool edges. Do NOT show any man-made pool details. The location must feel like clear tropical ocean water: - natural blue ocean water - realistic sunlight rays from above - subtle suspended particles - natural underwater haze - depth and open-water feeling - believable underwater light refraction - no artificial pool look If the bottom is visible at all, it should look like a natural pale sandy seabed, soft and organic, not geometric or tiled. CAKE: Preserve the birthday cake very closely: - same round cake - same white frosting - same colorful sprinkle coating - same candle arrangement - same proportions - same overall appearance ABSOLUTE FIRE PROHIBITION: THE CANDLES ARE COMPLETELY EXTINGUISHED FROM THE FIRST FRAME TO THE LAST FRAME. THE CANDLES MUST NEVER BE LIT. THERE MUST BE ZERO FIRE. ZERO FLAME. ZERO GLOWING WICK. ZERO EMBER. ZERO SPARK. ZERO SMOKE FROM A RECENTLY EXTINGUISHED FLAME. ZERO LIGHT EMISSION FROM THE CANDLES. The candles are already unlit before the video begins. They remain unlit for the entire 8-second video.
