AI motion transfer: one performance, any character
Kitsune turns one video into many. Upload a clip of a dance, a fight scene or a walk, add an image of your character, and get the same moves, the same timing and the same camera with your character performing them. Or swap one object or person in a clip and keep everything else.

How it works
- 1
Upload a motion video
Pick a clip with the moves you want: a dance, a fight, a walk cycle. At least 4 seconds; Kitsune uses up to the first 14.
- 2
Add a character image
Upload an image of your character, ideally full body and clearly lit. Add a short prompt if you want a different scene or style.
- 3
Get the result
Your character performs the same moves with the same camera and timing. The finished clip lands in your history and your assets.
The idea
One video, many versions
Upload any video and remake it with your own characters.
Examples
The same performance, three different characters.
What motion transfer is good for
A good performance is the hard part of a video. Motion transfer lets you film or find it once and reuse it: a dance trend performed by your brand mascot, a fight choreography played by an original character, a product walk-through presented by a stylised host, or the same routine shown by several characters for an A/B test. The motion clip sets the choreography, the timing and the camera; the character image sets who is on screen and how they look.
By default the result keeps the setting and style of your character image. Add a prompt such as "on a neon rooftop at night" or "in a watercolour style" to place the character somewhere else. Kitsune builds the rest of the instruction for you, so you do not need to learn how the model wants its references described.
Object swap is the second mode. Upload a clip, an image of the new subject and a few words on what to replace. It is useful for product placement, for trying a different car, bottle or outfit in a finished shot, or for replacing a stand-in with your character while the rest of the scene stays as it was.
Kitsune in the KreatorFlow studio
Two modes, one page
Switch between Motion transfer and Object swap. Each mode asks only for what it needs: a video, an image and, for a swap, what to replace.
Camera and timing kept
The motion clip drives the moves, the camera path and the beat, so edits made to music still line up.
Length follows your clip
The result is as long as the part of the clip Kitsune used, from 4 to 14 seconds. No duration to guess.
480p to 4K
Draft at 480p, post at 720p. Pro, Max and Business also render 1080p and 4K, finished with an upscaling pass.
Real cost before you generate
The Generate button shows the credits for your clip and resolution. Failed jobs are refunded automatically.
Clean downloads
No visible watermark or logo on the file you download. Every result is also saved to your assets.
Tips for better results
Pick a motion clip with one performer who stays in frame, a fairly steady camera and good light. Moves that are easy to read, such as a clear dance routine, transfer better than a blur of fast cuts. Trim long recordings to the part you want before uploading, because Kitsune uses up to the first 14 seconds.
For the character, a full-body image on a plain background works best, because the model can see the outfit and proportions it has to animate. If you want the same character in many videos, design it once in the AI character generator and reuse the image. For object swap, name the subject the way you would describe it to a person, for example "the blue bottle on the table", so the model knows exactly which one to replace.
Only use footage and characters you own or have permission to use. Putting a real person into a video needs their consent, and impersonation is not allowed. See the Acceptable Use Policy for what is still not allowed.
Motion transfer questions
What is AI motion transfer?
Motion transfer takes the movement from one video and gives it to a different character. You upload a clip of someone dancing, fighting or walking plus an image of your character, and the result shows your character doing the same moves with the same timing and camera movement.
What is Kitsune?
Kitsune is the KreatorFlow studio for motion transfer and object swap. It is named after the kitsune, the shapeshifting fox of Japanese folklore. It runs ByteDance's video models through BytePlus; KreatorFlow is an official BytePlus partner.
What does object swap do?
Object swap edits a video you upload. You add an image of the new object or character and type what to replace, for example the red car or the man in the hat. Kitsune asks the model to replace only that subject and keep the rest of the clip: the motion, the camera, the lighting, the background and the timing.
How long can my video be?
Clips need to be at least 4 seconds long. Kitsune uses up to the first 14 seconds of a clip, and the result is as long as the part it used. Upload MP4, MOV or WebM files of up to 50 MB.
How much does it cost?
Kitsune uses credits like the rest of the video studio, and the price depends on the clip length and resolution: a 5-second clip at 720p costs 60 credits and a 10-second clip at 720p costs 120 credits. The Generate button shows the exact cost for your clip before anything is charged, and failed jobs are refunded automatically.
Which plan do I need?
Kitsune is part of video generation, which starts on the Creator plan at up to 720p. Pro, Max and Business also render 1080p and 4K. New accounts get 10 one-time starter credits, which cover images only.
Will every result be perfect?
No. Motion transfer works best with one clearly visible performer, a steady shot and a character image that shows the full body. Very fast moves, heavy motion blur, several people in frame or a character image that is cropped at the waist can give weaker results. If a job fails, the credits come back automatically.
