# Magejutsu: recast a video you already have

> Magejutsu recasts an existing video with your characters, outfits, places, and products, keeping the motion, camera, cuts, timing, and sound as filmed.

Magejutsu recasts a video you already have. Bring a clip and photos of who or what should be in it, and it rebuilds the cast or swaps one thing while the motion, camera, cuts, timing, and sound stay as filmed. A director model watches your clip first and writes the edit, so you can start without a prompt.

## Overview

| Detail | |
| - | - |
| Category | Video |
| Inputs | 1 source video plus up to 30 reference images |
| Accepts | video, image, and your saved Characters and References |
| Runs on | Magejutsu, Magejutsu Lite, or Magejutsu Feather |
| Price | Gems on every plan; the Generate button shows the total before you run |
| Open | [mage.space/apps/magejutsu](https://www.mage.space/apps/magejutsu) |

## What Magejutsu is for

* Putting yourself, a saved character, or a client into an existing clip
* Music videos, dance trends, ads, and short films where the performance already exists
* Changing an outfit, a product, or a location without reshooting
* Replacing [Motion Control](https://docs.mage.space/models/pear-motion-control.md), which Magejutsu supersedes

## Modes

| Mode | What it does |
| - | - |
| Motion transfer | Keeps only the motion: the camera, cuts, and timing stay, and your references play every part |
| Object swap | Changes only what you point at, such as a person, an outfit, or a product, and keeps the rest as filmed |

## How to use Magejutsu

**1. Add a source video**

Upload a clip of 4 to 30 seconds (4 to 15 on Lite and Feather), pick one of
your creations, or press Remix on a clip in the motion library.

**2. Add references**

Add up to 30 images: characters, outfits, props, and places. Upload photos,
or choose From your creations, From your characters, or From your references
in the reference picker.

**3. Add directions, or don't**

Directions are off by default, and the director decides who goes where. Turn
them on to say what changes, mentioning references as `@image1` or, for a
Character you added in the picker, its `@handle`.

**4. Generate**

The recast keeps the clip's length, aspect ratio, cuts, and sound. It lands
in History, ready to download, share, or remix.

## Which model to pick

| Model | Source length | Resolutions | Best for |
| - | - | - | - |
| Magejutsu | 4 to 30 s | 480p, 720p, 1080p | The best recasts and the longest sources |
| Magejutsu Lite | 4 to 15 s | 480p, 720p, 1080p | Faster and cheaper, with fewer references reaching the render |
| Magejutsu Feather | 4 to 15 s | 480p, 720p | The cheapest and fastest, for motion transfer only |

See the [Magejutsu model page](https://docs.mage.space/models/magejutsu.md) for what each model supports.

## Tips

* One clear, front-lit photo per person is enough. Map each reference to its subject by position, such as "image 1 is the person on the left".
* A clip with a clearly visible subject and steady framing recasts best.
* Remixing a Magejutsu creation reuses its motion and settings, never its reference images.

## Limitations

* A source clip is required. Magejutsu edits footage; it does not invent it.
* The price follows the clip's length and the resolution you pick, and it is paid in Gems on every plan.
* You need permission for the footage and for any likeness in it, as with every face-editing tool on Mage. See [likeness and reports](https://docs.mage.space/policy/likeness-and-reports.md).
