How to swap a character in a video with AI and keep every move
Replace the person in any clip with yourself or a friend from one photo, and keep the moves and the camera. Character swap and face swap explained, with the steps and the fixes.
Motion control AI copies the moves of a reference video onto the person in your photo. How it works, which clips and photos give a clean result, its limits and its cost.

Motion control AI takes the movement from one video and gives it to someone else. You hand it a reference clip and a photo, and it returns a video where the person in your photo makes the moves of the original, at the same moment and from the same camera angle.
The term spread at the end of 2025, when Kling released Motion Control for its 2.6 video model, and plenty of tools offer it now. Every example on this page is a real result from Distribea Motion Control, taken from our library and our home page, so you can judge the method on actual frames.

Two inputs, always. The reference video carries the motion, and the image carries the person who will perform it.
The model reads the reference frame by frame. It estimates where the body is, how the arms and legs bend, where the head points and how the camera travels. Then it draws new frames in which the person from your image holds each of those poses.
Each frame of the result is drawn again by the model, so it can only copy what it can see clearly. A sharp, steady reference gives a clean remake. A dark or shaky one gives a messy remake, whatever the tool.
Tools split on one question: what stays from the original video?
Some keep your image as the scene. The character from your picture moves like the reference, but the background comes from your picture. Runway Act-Two works this way when you give it a character image, and it adds movement to the background of that image.
Others keep the original video as the scene and replace only the person. That is how Distribea's "Copy the motion" mode works: your photos take the place of the people in the video, and every move stays.

Everything that makes the fighter a different person came from a single photo. The green wall and the way he lifts his fists are the original clip's. To step into a specific clip, such as a trend or a film scene, you need a tool of this second kind.
A face swap changes the face and keeps everything else of the original actor, from the haircut to the clothes. It is enough when the actor already looks a bit like you from the neck down.
Motion control rebuilds the whole person. On Distribea you can also add a photo of your outfit, and the video shows you in your own clothes. On a full-body dance or a stunt, the difference shows straight away. Our guide to swapping a character in a video compares the two in a table.
Distribea's How it works page puts the rule in one line: one clear person with the body in view, in one scene without fast cuts. Break any part of it and something specific goes wrong.
With two people crossing in front of each other, the model has to guess which arm belongs to whom. If the person walks out of the frame or turns away for half the clip, it has nothing to copy during those seconds and invents the missing part.
Cuts are the sneakiest problem. A cut jumps to a new shot, and the face often shifts on that exact frame, so a clip filmed in one continuous take is worth looking for.
Distance matters as well. A dancer filmed from far away in a dark club gives the model a face a few pixels wide. Pick a clip where you can read the person's expression at a glance. On Distribea the clip lasts 4 to 30 seconds, in MP4 or MOV, from the library or from your phone.
Take the photo in daylight, facing a window, looking straight at the lens. Keep hair off your eyes and take off sunglasses or a cap that throws a shadow. Skip beauty filters: the model copies the face it receives, so a smoothed face gives a smoothed video.
The hardest moments are turns. When the person in the clip spins or shows their back, a single front photo leaves the model guessing what you look like from the side.

That is what a character sheet is for. You give one photo of your face, and the site draws you from every side: your face from four angles and your body from three, in one image. It is ready in about 2 minutes. Use it as your photo, and the video keeps your face when you turn your head or show your back.
Kling Motion Control animates one character per generation. When the reference shows several people, it uses the one with the largest presence on screen.
Distribea's Copy the motion takes one photo per person, up to four, and replaces each person with the matching photo. Duets and group routines come back with your friends in them, as the couple and the trio in our guide to making an AI dance video of yourself show.
Fast spins and hands passing in front of the face are the frames where models guess the most. Watch your result at full screen and check those moments before you post.
Length has limits. Distribea accepts clips of 4 to 30 seconds, and one of its two engines stops at 15 seconds: the panel shows each engine's limit and expected wait before you start.
Then there is the wait. A Distribea video takes about 15 minutes. You can leave the page, and the finished video waits in your History.
On Distribea, if a video fails, your credits come back. Kling's guide for version 2.6 says that when a complex or fast move makes the output shorter than the reference, the credits used are not refunded.
Kling charges per second. Motion Control 2.6 costs 5 credits per second in Standard mode and 8 in Professional, and version 3.0 costs 9 and 12. On October 25, 2026, its Standard plan showed $6.99 for the first month, then $8.80 a month for 660 credits: about 13 ten-second clips in 2.6 Standard. Our page on the Kling models covers the rest of the family.
Distribea shows the exact price under the Generate button before you start. The Starter plan's 3,000 monthly credits cover up to 6 Motion Control videos, for €19.99 a month billed yearly or €29.99 month to month, VAT included. There is no trial and no intro offer, and the same plan opens our royalty-free library of music, sound effects, footage and images. The plans are on the pricing page, and we compared five tools side by side in Viggle AI alternatives.

The video shows up in your History. To see more results first, our home page puts ten originals and their remakes side by side, with a line you drag between the two.
Motion capture records an actor wearing sensors or markers in a studio. Motion control AI estimates the pose from an ordinary video, so any clip you can download or film works as the reference.
Yes. On Distribea, upload a clip of 4 to 30 seconds from your phone or your computer, in MP4 or MOV. It keeps its moves and its camera.
On Distribea it does for clips from 5 to 15 seconds. Outside that range, plan to add the sound when you edit or post.
