By generating, you accept the Terms and confirm you and all real people shown are 18+, with permission to use the images.

A new character performance, guided by your clip

The reference video supplies the action and framing. Your images describe the character to put into that performance. AI uses both to generate a new clip, so choose this workflow when you want a character remake.

Bring your character into the scene

The new face, hairstyle, build and clothing are guided by your character images. You can start with a photo or an illustrated character and use several consistent views to describe the look.

Know what can change

The result is regenerated footage. Movement, background, fine details, audio and lip-sync may differ. If your task requires only a face change with the rest of the original preserved exactly, use a tool designed for that task.

How to swap a character in a video

Keep your video, references and result together in one workspace.

  1. Bring a video

    Paste a public TikTok, Douyin or Bilibili link, or upload MP4/MOV. Preview it and choose the action you want to recreate.

  2. Add your character

    Upload one or more images of the same character. A clear face plus a profile or full-body view can describe their appearance.

  3. Make the clip

    Add any extra instructions, choose output settings and review the credits. Generate, then watch and download from this page.

Video character swap for dances, memes and your footage

Use a reference clip to guide the action in a new character video.

Dance

Put your character in a TikTok dance

Paste a public TikTok dance link and add your character images. Pick the move you want to recreate. The video guides the movement and framing of the new clip.

For a full-body dance, choose a section where the dancer stays in view and the movement is easy to follow. Check the generated motion as well as the character’s face.

Optional instruction to try

Use the outfit in my character references and a simple dance-studio background.

Character remix

Recreate a Bilibili or Douyin clip

Choose a reaction, gesture or meme clip from Bilibili or Douyin. Add your AI character references and generate a new version of that moment.

Select the gesture or reaction itself rather than a long sequence of cuts. Use your images to describe the character; on-screen captions and fine details may be regenerated.

Optional instruction to try

Keep my character’s illustrated style and use a plain background so the gesture stands out.

Your footage

Swap a character in your own MP4 or MOV

Upload a clip you filmed and add your character images. Use the footage as a reference for an avatar performance, a reaction or a short character story.

You can act out the movement yourself and upload it directly, without posting it to a social network. Select one complete action before choosing the output length.

Optional instruction to try

Place my character in a sunny room with soft natural light.

Give the model a clear starting point

What to prepare

A public video link
TikTok, Douyin or Bilibili. A private, removed or restricted clip may not import. If you have the video file, use the upload option.
Or your own video file
MP4 or MOV, up to 200 MB and at least 2 seconds long. Preview the video and select the part to use; the current model’s clip limit appears in the tool.
Images of one character
JPG, PNG or WebP, up to 10 MB per image. Add a front view, profile or full-body view of the same character. The selected model determines how many images you can use.

One action in view

Choose a clip where the main person is easy to see. Preview the source before selecting the part to use; the model’s clip limit is shown in the tool.

One character, several views

Use consistent images of the same character. Face, hairstyle, clothing and full-body details help describe the look you want to carry into the new clip.

Plan the credits and check your finished video

Generation uses paid credits. The tool shows your quote before you submit, so you can adjust the settings first.

Set the reference and output lengths separately
The selected clip tells AI which action to use. The output duration sets the length of the new video. Choose both in the tool; changing one does not mean the other has changed.
Review the complete quote
The cost depends on the model, resolution, output duration and selected reference-video duration. Both reference and output seconds count toward the quote. Check the credits beside Generate after making changes.
Watch, download and keep a copy
The result appears here and in your account history. Videos are not published automatically. Finished videos and creation records are available for 30 days; download the ones you want to keep.

Before you share it

Watch the whole result. If you want another version, change the reference, selected action or optional instruction before generating again. A new generation uses credits.

  • Character

    Check the face, hairstyle and outfit throughout the clip. Consistent reference images give the model a clearer description of one character.

  • Movement

    Look at the complete action, hands and body, including moments when the subject turns or is obscured. Try a clearer reference section if needed.

  • Sound and details

    Listen to the audio and check lip-sync, captions and background details. Use the finished clip only after reviewing the parts that matter to you.

Use videos and character images you own or have permission to use. Get consent before using another real person’s likeness.

Plans for your next character video
