The art of illusion for video: restyle, recast, rewrite
Genjutsu AI rewrites the video you already have. Upload a 2–15s clip and our in-house generation pipeline casts a new character, changes the outfit, swaps the product, moves the location, restyles the whole scene between live-action, 3D and anime — or replaces a face — while keeping the original motion, camera and timing.
Hey Product Hunt! I'm Alex, the creator of Genjutsu AI.
**The problem**: Editing a video you already shot is painful. Need the same take
but with a different person, outfit, product or location? You reshoot. You track
masks for hours. You give up and post the original.
**Our solution**: Genjutsu AI keeps what made the clip work — the motion, the
camera, the rhythm — and changes what you need. Upload a 2–15s clip, pick a mode,
and get a new take back.
**The name**: 幻術 (Genjutsu) is the art of illusion. That's exactly what this is —
the performance is real, the reality around it is crafted.
**What makes it special**:
- 7 modes: Motion Transfer, Character Swap, Outfit Swap, Object Swap, Background
Swap, Restyle and Face Swap
- Style preserved — photoreal stays photoreal, cosplay-grade anime stays anime
- Motion, camera path and timing from your source clip are kept
- Sound matched to the edit by default; editing modes can keep original audio
- 196+ built-in templates to start from
**Why I built this**:
I kept watching small creators do what used to take a VFX team — and it looked like
magic. I wanted that to be a normal upload, not a studio budget.
I'm here all day — what would you cast first? 🎬
