Genjutsu FAQ

What is the reference effect Genjutsu?

Genjutsu lets you transform an existing video in two ways: transfer its motion into a new cast, location or look, or swap selected elements while keeping the rest of the shot intact.

What's the difference between Motion Transfer and Object Swap?

Motion Transfer keeps the motion, camera and timing while rebuilding the scene from your references. Object Swap changes a selected character, outfit, product, location or object while preserving the rest of the original shot.

What can I change with Genjutsu?

You can recast characters, change locations, introduce products or wardrobe, or replace individual elements in an existing video using your own references and prompts.

How long can my reference video be?

Genjutsu currently supports reference videos from 4-30 seconds, as shown in the generator.

How many reference images can I add?

You can add up to 30 reference images for characters, products, wardrobe and other visual elements.

Do I need video editing experience?

No. Upload your video and references, choose Motion Transfer or Object Swap, describe what you want to change, and generate.

How does pricing work?

Generations use the standard the reference effect credit system. Each run shows its credit cost before you generate, so you always know what a render will use.

Can I use the results commercially?

Yes — what you generate is yours to publish across organic and paid channels, subject to the reference effect's Terms of Use.
