In “Create a video”, the “Motion transfer” tool replaces the person in a video with another character. Your video keeps its gestures, its expressions and its camera moves: only the person changes. There is no free text field. You provide a video and a person, you choose the scene and the resolution.

​
What you provide

You choose a single person: an image, or a character from your account.

​
The two scenes

  • “Video’s scene”: only the person changes. Setting, light and camera stay those of your video. This is the default replacement.
  • “Image’s scene”: the scene is recreated around the person in the image, with the movements of your video. This choice is included in certain plans only (the screen says so).

​
Choosing the source video well

  • A clearly visible person: this is the person who will be replaced. Pick a video where they fill the frame, without being hidden.
  • Lasts between 3 and 30 s. A longer video is refused: trim it before uploading. A “30 s” file that lasts 30.2 s is trimmed to 30 s, not refused.
  • A file your browser can read: use MP4 or MOV.

​
Choosing the person’s image well

  • At least 340 pixels per side. Below that, the image is refused.
  • A width to height ratio between 2:5 and 5:2. An image that is too stretched is refused: crop around the person.
  • Head, shoulders and chest visible, front facing, well lit, face sharp.

​
Before / after

Video: a party with ten people dancing, 45 seconds. Image: a selfie from far away, head cut off.The file is too long, the person to replace isn’t clear, and the image shows neither the face nor the chest.

​
Common mistakes

  • Video too short or too long: 3 to 30 s. Videos outside that range don’t even show up in the picker’s library.
  • Image too small or too stretched: 340 px per side at least, ratio between 2:5 and 5:2.
  • Image and character at the same time: choose one or the other.
  • Forgetting to tick the rights box: it is mandatory. You must hold the rights to the video and have the consent of the people shown. Never use a person’s image without their consent, nor to deceive or harm.
  • Expecting text or voice: the tool redoes a movement, not a narration.

​
Settings that go with it

  • Resolution: 720p by default. A higher resolution costs more per second.
  • Price: it is counted per second of transferred video. Test on a 5 to 10 second excerpt before a 30 second video.
  • Your video and your image stay in your library, even if the generation fails.
  • Character: create a character with a portrait in the character tools to reuse it from one transfer to the next.
To remake a video your way, with a new scenario, see remaking a video from a link instead.

​
Before launching

The “Replace the person” button shows the price. It is counted per second of video: a shorter video costs less. Try an excerpt first.

​
What the tool does not do

  • It rewrites no scenario, no text, no voice: the output is your video, with another person.
  • It doesn’t change the length: the video is transferred as is, trimmed to 30 s if it goes over.
  • It doesn’t replace “Video remake”, which redoes an entire story your way: see remaking a video from a link.
