What Is Genjutsu AI?
Genjutsu is a video-to-video model by Higgsfield. You upload an existing clip; the model rewrites the character, outfit, scene, or props in that footage while preserving the original motion, camera movement, and timing. It is not a from-scratch text-to-video generator — the source take is the skeleton, and Genjutsu changes who and what you see on that skeleton.
How Genjutsu Works
Three steps: keep the move, rewrite the subject.
- 1
Upload the original clip
Drop in the video whose motion, camera path, and timing you want to keep.
- 2
Describe the result
Write who or what should appear instead — character, outfit, scene, or prop.
- 3
The model rewrites the subject
Genjutsu swaps the subject while preserving the original movement and shot timing.
What You Can Change
Full restage or a local swap — character, wardrobe, location, or a single object.
Characters
Replace the person on screen with another identity while they still walk, turn, and hit the same marks.
Outfits
Keep the performance, change the wardrobe — full costume swap or a single garment.
Scenes
Restage the location around a locked camera move: interior to alley, day to night, studio to street.
Props
Swap the object in hand or in frame without rebuilding the take.
Swap a man in a black jacket for a woman in a red evening dress on the same sidewalk walk.
Replace street clothes with samurai armor while the original handheld camera still breathes.
Turn a living-room talking-head into a rainy Tokyo alley at night, keeping the head turns.
Swap a coffee cup for a glowing crystal orb without changing the hand path.
Restyle the subject as an anime character and keep the original cut timing.
Replace a modern car in a tracking shot with a vintage motorcycle.
How to Use the Generator
Five steps from upload to download.
- 1
Upload your clip
Use the upload box in the generator. This is the source of motion — camera move and duration stay with this file.
- 2
Pick Motion Transfer or Objects Swap
Motion Transfer rewrites the performer against the original move. Objects Swap targets clothing, props, or other objects in the frame.
- 3
Write the result you want
Prompt the new identity, outfit, location, or object. Be specific about what changes and what must stay.
- 4
Choose resolution and generate
Select 480p, 720p, or 1080p. Credits are reserved from a server-side estimate before the job starts.
- 5
Download the rewritten video
When the task finishes, download the new clip. Timing should match the original take.
Genjutsu Prompt Ideas
Start with a concrete rewrite, then say what motion must stay.
Armor over street clothes
Swap the street clothes for full samurai armor. Preserve handheld camera movement and timing.
Night alley restage
Change the living room to a rainy Tokyo alley at night. Keep the talking-head framing and head turns.
Prop swap
Replace the coffee cup in her hand with a glowing crystal orb. Do not change the arm motion.
Anime restyle
Turn the subject into an anime character with the same hairstyle color. Keep the original cut timing.
Empty landscape
Replace the background crowd with empty snowy mountains. Keep the original tracking shot.
Disco wardrobe
Outfit swap to 1970s disco sequins. Keep the original dance choreography.
Vehicle swap
Replace the car with a vintage motorcycle. Keep the tracking shot and speed.
Genjutsu AI Pricing
No subscription. Choose a one-time credit pack and spend credits on Genjutsu Motion Transfer or Object Swap.
Each generation consumes API time equal to your input clip duration (rounded up to the next second). Credits are calculated from that estimate on the server before the job starts — longer clips and higher resolution cost more.

What Creators Say About Genjutsu AI
Editors, producers, and short-form teams using video-to-video to keep the original motion
I swapped the actor in a walk-and-talk and the camera still tracked the same path. Genjutsu kept the motion so the edit dropped straight into the cut.
Sophie Miller
Freelance Editor
Object Swap let us restage a product in a new outfit without reshooting. Original timing stayed intact — that is the whole point of video-to-video.
Michael Chen
Creative Director
Pay-per-generation credits beat a monthly Higgsfield seat for our volume. We run a few Genjutsu jobs a week, not every day.

Wardrobe tests used to mean another studio day. Now I upload the take, prompt the look, and keep the original blocking.

Minutes, not overnight renders. I rewrite who is in the clip, download, and post. Motion transfer is what makes it feel like the same shot.
Emma Zhang
Short-form Creator
We use it for animatic stand-ins: same camera move, different character. Concept reviews got faster because the timing is already locked.

Credits are transparent enough for client billing. Each job is one clip, one prompt, one charge — no unused subscription sitting in the budget.
Jessica Li
Agency Producer
Scene swap on a locked tracking shot sold the location change. We still had to grade, but we did not have to recast or rebuild the move.
Tom Anderson
Ad Creative Director
I pick 720p for drafts and 1080p for finals. Paying only for seconds of input video is easier to explain than a studio plan.
