AI Motion Transfer
AI motion transfer turns a photo of a person into a video of them performing the moves from another clip
What is AI motion transfer?
AI motion transfer turns a photo of a person into a video of them performing the moves from another clip: upload a full-body photo and a motion video up to 30 seconds (a dance, a walk, a performance), and the person in the photo does the same thing for the same length, at 720P or 1080P. On blubiu it runs on Kling's motion-control model, which needs a human figure.

Who it's for
- +You have a dance or trend video and want a specific person to perform it without filming them.
- +You have a photo of a real person (yourself, a model, a presenter) and need them to walk, dance or gesture on camera.
- +The choreography has to be exact, copied from reference footage rather than described in a prompt.
- +You sell products or teach online and want a photo of the presenter to walk in, turn and gesture for a short intro.
- +Your routine runs longer than 15 seconds in one take: motion clips here can run up to 30 seconds, while the other video generation models on blubiu stop at 15.
When not to use it
- −Your character isn't human. Robots, animals and mascots are rejected (and refunded); to put a non-human IP character into real footage, replace the person in a video instead. AI Character Swap for Video →
- −No existing video shows the motion you want. Describe it in a prompt and animate your image with image to video. AI Image to Video Generator →
- −Your motion clip is longer than 30 seconds. Split it into parts and run each one.
How to use AI motion transfer
- 01
Add a full-body photo
One real person, head to feet, PNG or JPG. This sets who moves. Robots, animals and mascots are rejected by the model.
- 02
Add the motion video
A dance, a walk or a performance up to 30 seconds, with the movement clearly visible; full or half body is ideal. This sets how they move, and the result has the same length.
- 03
Choose orientation and resolution
By default the character faces the way the person in the video does; choose the image option to keep the direction from your photo. Start at 720P and rerun the keeper at 1080P.
Tips for better AI motion transfer results
Use one real person, head to feet
The model first has to find a human body it can map the moves onto. In our tests on 2026-09-20, full-body photos of real people worked, while a robot character was rejected with "no valid characters detected" and the credits came back. Crop out anyone else and keep the feet in the frame.
Pick a motion clip with one clear performer
The moves are read from the person in the clip, so choose footage where that person stays in frame and the movement is easy to see, shot full body or half body. Trim away intros, cutaways and any moment where the performer leaves the frame.
Trim the clip: the result is as long as it is
The result runs as long as the motion video and is billed per second of the result, counted in whole seconds and rounded up, so a 7.4-second clip is billed as 8. Cut the clip down to the moves you need before you upload it.
Set the orientation on purpose
Follow the motion video (the default) turns the person to face the way the performer does. Choose follow the character image when the direction in your photo matters, for example when the presenter should keep facing the camera as in the photo.
Draft at 720P, finish at 1080P or above
Test a new photo and clip pairing at 720P. When it works, run it again at 1080P; that is a new generation, so check it once more. For 2K or 4K, send the 1080P result to the AI video upscaler, which takes clips up to 120 seconds, so a full 30-second result fits.

AI motion transfer FAQ
Can I try AI motion transfer for free?
Yes. The Free plan includes monthly credits you can spend here, and the Generate button shows the exact cost before you confirm. A short motion clip at 720P is the cheapest test, and failed runs are refunded automatically.
How is motion transfer billed?
Per second of the result, at the rate for 720P or 1080P. The result is as long as your motion video, so trim the clip to just the moves you need before uploading. The Generate button shows the total first.
How long can the motion video be?
Up to 30 seconds, and the result matches its length. For a longer routine, cut it into parts of 30 seconds or less, run each part with the same photo, and join the results.
Why does it say no valid characters were detected?
The character photo isn't a person the model accepts. The message mentions the video, but in our tests on 2026-09-20 the cause was the image: robots, animals and mascots were rejected, while full-body photos of real people worked. The credits are refunded automatically; try again with a full-body photo of a real person.
Motion transfer or replace person in video: which should I use?
Use motion transfer when your character is a real person in a photo and you want them to perform moves from a clip up to 30 seconds; only the result's seconds are billed. Use Replace Person in Video when the character is non-human, such as a robot, or when you want to keep the original video's background, camera and lighting and swap only who is in it. That tool takes source videos up to 15 seconds and bills both the source and the result.
What does character orientation change?
It decides which way the character faces. Follow the motion video (the default) makes them face the way the performer does; follow the character image keeps the direction they face in your photo.
Can I use a photo of someone else?
Only with their agreement. Use a photo of yourself or of someone who has agreed to be animated, and say the clip is AI-made when you post it. Robots, animals and mascots aren't accepted at all; for those, replace the person in a video instead.
What resolution is the AI motion transfer result?
720P or 1080P, your choice, at the length of the motion video. For 2K or 4K, upscale the finished clip with the AI video upscaler afterwards.
Is AI motion transfer the same as motion control AI?
Yes, two names for the same idea: the moves come from a reference video and the look comes from your photo. This page walks through the job step by step; the motion control AI page compares it with character swap and prompt-based video, and answers whether it is free and whether cartoon characters work.
Is this the same as Kling Motion Control?
Yes. This tool runs Kuaishou's Kling motion-control model, version 2.6, behind a short form: a photo, a clip, the orientation and the resolution. The Kling Motion Control page covers the model itself and lists the current rates.
