​What is Character to Video?

Instantly transform any video by replacing characters. Swap faces, bodies, and styles with our AI animator while preserving every motion perfectly.

How It Works (Step by Step)

Step 1 - Upload your motion video

Select any video that shows the movements you want to replicate; MP4, AVI and MOV formats are supported

Step 2 - Upload Your Character Image

Add your AI‑generated OC, a photo, or any character image (up to 10MB)

Step 3 - Generate & download

Let DomoAI animate your character with the reference motion. In seconds, your new character appears in the video

​How do I get better results?

​Input quality guidelines

Ensure you have sufficient credits, as longer clips and higher resolutions require more credits.

  • An input video file (MP4, MOV or AVI).

  • An input character image(JPEG, PNG or JPG, 10MB).

​Material selection

  • Video person and image character should match as closely as possible: Half-body to half-body, full-body to full-body

  • Close-up shots generate more natural and obvious expression synchronization

  • Use more realistic character materials—face differences will be smaller
