Motion Transfer and Object Swap

Keep the motion. Change everything else.

Upload a video and a picture. Your character performs the same moves, with the same camera and timing. Or change just one thing in a shot and leave the rest alone. No editing experience needed.

Motion Transfer

Add a character picture to a motion video, or describe the character instead. The motion, camera and timing stay exactly as filmed, and your character takes the place of the performer. Add outfit, prop or location pictures if you want them in the shot. No prompt required when you add a picture.

Transfer motion

Object Swap

Say what should be different, a person, an outfit, a product or the text on a sign, and attach reference pictures. Everything else in the shot stays as it was.

From footage to finished clip in three steps

  1. 01

    Add your footage

    Upload a video of 4 to 30 seconds. Phone footage, a dance clip, a meme or an AI-generated shot all work.

  2. 02

    Add your references

    Reference pictures are optional, up to 30 in total. For Motion Transfer, the first is your character and the rest can show an outfit, props or a place; without pictures, describe the character in the prompt. Object Swap also takes a short description of what should change.

No prompt for Motion Transfer

Motion Transfer already knows the job: copy the motion, camera and timing. A picture and a video are enough to start.

Up to 30 reference pictures

Motion Transfer and Object Swap accept characters, outfits, props and locations as references and keep them consistent across the shot.

Output length, aspect ratio and camera follow your original clip. Choose 480p for drafts and 1080p for the final cut.

Frequently asked questions

What is Motion Transfer?

Motion Transfer copies the movement, camera and timing of a video onto a different character. You provide a motion video and a picture of the character. The performer in the video is replaced, and the background and pacing stay as filmed.

What is the difference between Motion Transfer and Object Swap?

Motion Transfer replaces the person in a clip with your character. Object Swap changes one thing you describe, such as an outfit, a product or a sign, and leaves everything else in the shot untouched.

Do I need to write a prompt?

Not for Motion Transfer. A picture and a video are enough, and you can add a short note if you want to guide the result. No picture? Describe the character in a short prompt instead. Object Swap needs a short description of what should change.

How long can the video be?

Between 4 and 30 seconds. Only the first 30 seconds of a longer video are used, and a shorter video is billed as 4 seconds. The result has the same length as the part of the video that was used.

How many reference pictures can I use?

They are optional, and you can use up to 30 in each mode. In Motion Transfer the first picture is the character, and the others can show an outfit, props or a location. In Object Swap they show characters, outfits, products and locations.

Are uploads checked?

Yes. Pictures, videos and results are checked against our usage policy, and requests that break it are refused. Only upload footage and pictures you have the right to use, and do not use other people's likeness without their permission.

Is there an API?

Yes. Both modes are available through the same REST API, CLI and MCP server as the rest of WaveSpeedAI, at the price shown on their model pages.
