How Genjutsu AI prompts work here
Choose the change type first. It tells the model what kind of edit to make and what to protect: Character replaces the person, Outfit only the clothes, Product the featured object, Background the place, and Style the rendering. Your prompt then fills in the specifics: which person or object, which image, and any detail that matters to you.
Because the editor already asks the model to keep the source duration, motion, timing, camera movement, cuts and framing, the most reliable prompts are short. "Replace the woman in the red dress with the person in Image 1" beats a paragraph about choreography.
Copyable prompt templates
Use Image 1 for the person on the left and Image 2 for the person on the right. Keep each person's hairstyle from the photos through every turn.
On built-in clips the mapping is automatic; this sentence only adds detail.
Replace the woman in the red dress with the person in Image 1, using her face, hair and body from Image 1 and the outfit from Image 2. Leave the man beside her unchanged.
Change only the clothing of the person to the outfit in Image 1 (front) and Image 2 (back). Keep the original shoes.
Replace the bottle he drinks from with the can in Image 1, matching the label and colours from Image 2. Keep how it is held and tilted.
Move the scene to the beach in Image 1 at sunset. Keep both people, their positions and their walk; match the light and shadows to the new place.
Restyle the whole clip as 1990s hand-drawn anime: flat cel shading, thick ink outlines, limited palette. Keep faces recognisable.
Match the painting style of Image 1 across every frame; keep the same framing and timing.
More looks are listed on the video to anime page.
Say which one in multi-person clips
When a clip shows several people, name the one you mean by something visible at the start:
- Position: "the person on the left at the start", "the one in the front row".
- Clothing: "the man in the blue track jacket", "the woman in the black cap".
- Action: "the person who starts seated", "the one holding the camera".
For two people with two photos, the duo swap page shows how Image 1 and Image 2 map to each lead.
What not to write
- Two changes at once. Swap the person in one generation and the background in another.
- A word portrait when you gave a photo. Describing a face in words competes with the image.
- Length or speed changes. "Make it longer" or "slow it down" fight the source timing; pick the window length instead.
- Extra people, captions or logos you do not want; they are only added when you ask for them.
- "Pixel-perfect" or "exact". These words do not make a generative edit identical; check fast turns, hands and small text in the result.
