Two Ways to Create the Video
☁ SIMPLE METHOD Two ready-to-use generations. Choose this if you want to recreate the video quickly.
☁ ADVANCED METHOD Adds a separate wide-shot generation for a more cinematic and consistent result.

Match identity, face, body proportions and clothing exactly.
@image3 — Creature appearance inspiration.
Use this reference only as design inspiration.
Preserve the overall anatomy, proportions and recognizable silhouette.
Do not reproduce the exact surface details.
Create a new ultra-photorealistic marine predator with natural biological textures.
It must look like a real deep-sea animal captured by a camera, not like a CGI creature.
------------------------------------------------
------------------------------------------------
The humans always remain side by side.
The distance between them never changes.
They always move as a single pair.
The humans continuously make subtle natural swimming movements to maintain neutral buoyancy.
They never appear frozen or motionless.
They do not travel through the water.
The creature always remains far below the humans.
The creature is vastly larger than the humans.
The size relationship never changes.
The creature is always partially hidden by depth haze, suspended particles and underwater light absorption.
Its features are never perfectly sharp.
Large areas of empty open water dominate every shot.
The humans remain the primary subject.
The creature is never presented as a hero shot or portrait.
------------------------------------------------
The camera remains completely static during every shot.
Only natural underwater micro-shake.
------------------------------------------------
Real underwater light absorption.
Visibility naturally decreases with depth.
------------------------------------------------
Looks like genuine underwater footage.
The creature must look biologically believable.
Its skin has natural imperfections, subtle asymmetry and realistic organic textures.
Avoid the appearance of CGI, concept art or digital creature rendering.
------------------------------------------------
------------------------------------------------
Extreme long establishing shot.
The camera is extremely far from the humans.
The humans appear as tiny distant silhouettes, barely larger than specks against the bright surface.
They serve only as a scale reference for the creature.
The creature is already fully present before the shot begins.
Its enormous head is fully visible in profile.
It occupies the lower-right area of the frame.
The head does not enter the frame.
The creature silently watches the humans.
Most of the head is visible, but depth haze, suspended particles and underwater light absorption soften its details.
The full head is never perfectly sharp.
The rest of the body disappears into the abyss beyond the frame.
The humans gently maintain position with small corrective swimming movements.
They do not travel forward or backward.
The creature remains perfectly still.
------------------------------------------------
The camera is several meters below the humans looking upward.
Only the two humans are visible.
No creature appears in the frame.
The camera is completely locked-off.
The camera does not drift, pan, tilt, rotate or translate.
The humans remain shoulder-to-shoulder throughout the shot.
The distance between them never changes.
They move together as a single pair.
Their faces are faintly recognizable but still distant.
They continuously make subtle natural swimming movements to maintain neutral buoyancy and hold position.
They do not travel forward or backward.
The humans occupy only a small area near the upper part of the frame.
The remaining frame is empty open ocean.
------------------------------------------------
The humans occupy the upper-left portion of the frame.
The creature is already present before the shot begins.
The creature faces almost directly toward the camera.
Its gaze reaches both the humans and the viewer.
Its enormous head dominates the entire right side of the frame.
The humans appear smaller than the creature’s mouth.
Large portions of the head extend beyond the frame edges.
The camera cannot capture the entire head.
The creature is more frontal than in Shot 1, but it is still not a portrait.
The creature never changes its orientation.
Its only movement is an almost imperceptible backward translation deeper into the abyss while maintaining exactly the same orientation.
Depth haze gradually obscures the creature.
Very subtle blue bioluminescent speckles are visible across parts of its scales.
It never illuminates the surrounding water.
Eventually only a faint silhouette remains before disappearing into darkness.
The humans continue making subtle corrective swimming movements while watching the creature disappear.
Option 2. Advanced Method
For anyone who wants a more cinematic and consistent wide shot.

Editing
Simple Method
1. Place the first generation on the timeline.
2. Place the second generation immediately after it.
3. Trim unwanted endings and any unsuccessful transitions.
Advanced Method
1. Place the first generation on the timeline.
2. At the beginning of the second generation, replace its opening wide shot with the separate 4-second Pro generation.
3. After the wide shot, keep Shots 2 and 3 from the second generation.
