@image1 — strict identity reference for the main man. Preserve exact face, age, skin tone, hair, physique, body proportions, and overall appearance throughout. Stable identity in every shot. @image2 — strict outfit reference for the man. Preserve the exact diving outfit / scuba gear, colors, fit, materials, proportions, and styling. @image3 — strict reference for the huge sea monster. Preserve the overall creature identity, scale, anatomy language, silhouette, tentacles, facial structure, skin texture, and threatening presence. It must feel gigantic and truly alive. @image4 — ATMOSPHERE / MOOD REFERENCE ONLY. Use this only for underwater mood, lighting tone, dramatic cinematic ambience, color feeling, and environmental emotion. Do not copy composition literally. FORMAT 9:16 vertical, approximately 15 seconds. Ultra-realistic cinematic underwater sci-fi action scene, highly photorealistic, premium movie realism, dynamic action, authentic cinematic performance. CORE IDEA Create a short excerpt from a modern underwater sci-fi action film. A man in scuba gear is deep underwater in the ocean when he encounters a gigantic tentacled sea monster. The sequence is tense, kinetic, and immersive: glowing plankton drifts through the water, dramatic shafts of underwater light cut through the darkness, fish scatter, danger builds fast, and the man desperately tries to escape and hide among rocks / in a sea cave while the monster attacks. STYLE / WORLD A dramatic underwater action sequence with rich depth, floating particles, bubbles, schools of fish, distant sharks, rocky ocean terrain, and moody blue-green underwater light. The water must feel dense and real. The environment is alive: plankton glows softly, currents move cloth and particles, fish react and flee, bubbles trail behind movement. No one is static. CAMERA — CRITICAL Dynamic cinematic action camera. The camera keeps moving and shifting perspective to capture urgency and scale. Use a strong sequence of readable cinematic shots with smooth but energetic motion: - establishing wide shot; - high-angle wide shot of the man from the monster’s perspective; - tracking medium shot as the man swims; - medium close side shot as he turns back; - low-angle medium shot of the monster from the man’s perspective; - close-up of the man looking upward as shadow falls across his face; - close-up detail of his fins kicking fast; - close-up detail of the monster’s skin / face / surface texture; - dynamic medium / medium-wide shot orbiting around the man and monster as he tries to hide and the monster attacks. The camera should feel cinematic and urgent, but the key action must remain clear and readable. SCENE FLOW (0–2s) — ESTABLISHING / TRACKING Begin with a dramatic underwater establishing shot deep in the ocean. The man from @image1 wearing @image2 swims through open water near rocks and a sea-cave area. Schools of fish surround him; a few sharks glide farther away in the background. Glowing plankton floats around him. Then transition into a tracking medium shot following him underwater as he swims forward. (2–4s) — SENSE OF THREAT High-angle wide shot from above, as if from the creature’s looming perspective, making the man feel small and exposed below. Fish suddenly scatter away. Then a medium close side shot: the man senses something, turns his head and upper body, and looks back over his shoulder. He is alert, breathing hard through the scuba gear, eyes active, body tense. (4–6s) — MONSTER REVEAL Low-angle medium shot of the huge sea monster rising from below / from the seafloor. It emerges powerfully through drifting silt and dark water, tentacles moving, body surging upward. It must feel massive, alive, and dangerous — not static. Cut to a close-up of the man looking upward in fear and shock as the creature’s shadow covers his face. (6–8s) — ESCAPE Close-up detail shot of the diver’s fins kicking hard as he accelerates away. Bubbles trail behind him. Then a fast tracking shot as he swims desperately toward rocks / a sea cave for cover. The monster pursues, tentacles whipping through the water behind him. (8–11s) — CREATURE DETAIL / CHASE Close-up detail shot of the monster’s skin and face texture: wet, alien, organic, intimidating, with convincing underwater motion. Then shift into a dynamic medium-wide shot orbiting around both characters as the diver reaches the rocky shelter and tries to squeeze into a cave / hide among rocks while the monster closes in. (11–15s) — ATTACK / IMPACT The man ducks into cover beneath rocks / near the cave. The monster lashes out with a huge tentacle and smashes the rock formation / cave edge directly above or beside him, sending debris, silt, and particles exploding through the water. The man narrowly avoids the strike and recoils / twists away. End on a tense dynamic shot with the monster still attacking and the diver still struggling to escape. PERFORMANCE / REALISM The diver must feel very alive: natural blinking, breathing behavior, eye focus, tension in posture, urgent body movement, realistic swimming mechanics, realistic turns, fear, panic, and survival instinct. The monster must also feel alive and active: swimming, surging, turning, striking with tentacles, reacting physically, never frozen or posing. AUDIO FEEL Underwater cinematic ambience: muffled ocean pressure, bubbles, distant creature movement, debris impacts, rushing water, fish scattering, heavy underwater action tension. No music description needed unless generated naturally by the model. IMPORTANT - Underwater scene only. - Keep the man’s identity stable from @image1 and outfit stable from @image2. - Keep the monster visually grounded in @image3. - Use @image4 only for mood / lighting / atmosphere. - Show clear scale difference: the monster is gigantic. - Include fish and some distant sharks, but the main focus is the diver and the monster. - Nobody is static: both the man and the monster are constantly moving and reacting. - The monster actively attacks with tentacles; it does not just float and stare. - The cave / rock shelter is damaged by the monster’s strike. - Strong cinematic shot progression and dynamic camera. - No morphing, no anatomy glitches, no extra limbs, no broken scuba gear, no deformed hands, no face distortion, no flicker, no ghosting, no temporal smearing.
