Effect · Hulk
Hulk AI effect — one photo, one transformation.
The Hulk effect is more violent than most people expect, and it comes out red rather than green. Its built-in instruction shatters the subject's body into fragments, gathers the pieces with a surge of force, and rebuilds them as a huge towering giant in tattered shorts, roaring, with debris swirling around it.

Inside the effect
What the Hulk effect actually does.
The instruction behind this effect is unusually detailed, and worth knowing before you run it. The character's body shatters into numerous fragments. From the dispersing pieces a strong force emerges and remoulds them into a much larger, more powerful form: the muscles enlarge and reshape into a huge, towering giant. The remnants of the shredded body vanish into chaos, leaving a figure with bulging muscles, a fierce expression and nothing but tattered shorts, roaring hard enough to shake the ground while debris swirls around it.
The instruction specifies a red giant, and that is what the effect produces — a deep red physique, not the green one the name leads people to expect. If you were after green, this is not the effect; the Superhero category holds seven templates and the others take different approaches.
The shatter-and-rebuild structure is also why the effect wants a whole body. It is not painting muscle onto your photo; it is destroying the figure it was given and constructing a larger one in the same place.
Source photos
Photos that work, and photos that don't.
One-tap effects have one input. Which photo you pick is the whole of your creative control.
Full or half body, standing
The rebuild needs a figure to rebuild. Head-and-shoulders crops leave the effect with nothing to shatter.
Room around the subject
The new form is explicitly bigger than the old one. If your subject already fills the frame, the giant has nowhere to grow into.
A background that can take damage
Streets, rubble and open ground suit the debris. A tidy living room does not.
A front-facing stance
The roar and the chest are the payoff. A profile or a back view throws both away.
Failure modes
Where it goes wrong.
The three ways this particular effect disappoints people, and what causes each one.
People expect green. The instruction says red, and red is what arrives — this is the single most common surprise on this effect, and it is not a fault in the generation.
Tight portraits fail structurally. There is no body to fragment, so the effect produces a head that grows rather than a transformation.
Seated or leaning subjects rebuild badly. The instruction describes a towering standing figure; a person sitting on a sofa gets stood up in a way that rarely survives contact with the furniture.
How it works
Running Hulk in four steps.
Use a standing photo with space around it
The new body is bigger. Give it somewhere to be bigger in.
Face the camera
The reveal is a chest and a roar. Both need to be pointed at the lens.

Expect red
If the colour is wrong for what you are making, try another effect in Superhero rather than re-rolling this one — the colour is in the instruction, not in the randomness.
FAQ
Hulk, answered.
What does the Hulk effect do to a photo?
Its built-in instruction shatters the subject's body into fragments, then a surge of force remoulds those pieces into a much larger form — a towering giant with enlarged muscles, a fierce expression and tattered shorts, roaring while debris swirls around it.
Why is the Hulk effect red and not green?
Because the effect's built-in instruction specifies a red giant. The colour is written into the effect rather than chosen at random, so re-rolling will not turn it green. The Superhero category holds seven templates if you want a different look.
How much does the Hulk effect cost?
2 credits per run on the Vidu engine, producing a 4-second clip at 720p in the aspect ratio of your photo. Nothing you export is watermarked, on any plan.
What photo works best for the Hulk effect?
A standing, front-facing shot with space around the subject. The effect destroys the figure it is given and builds a larger one in its place, so it needs both a body to work from and room for the new one to occupy.
Does the Hulk effect work on a close-up portrait?
Poorly. With no body in frame there is nothing to fragment and rebuild, so instead of a transformation you get a head that grows. Use a photo that includes at least the torso.
