Motion Swap transfers the human motion from a reference video onto a character in your avatar image. Credits are charged per second of the reference video (minimum 3 s, maximum 30 s), so a 10 s driving clip costs 40 credits at 720p.

How to use Motion Swap

1. 1Navigate to Create → Motion Swap in the sidebar.
2. 2Upload a driving video (MP4 or MOV, 3–30 s) — this video defines the motion that will be applied to your avatar. The credit cost is calculated automatically from the video duration.
3. 3Select an avatar: choose a saved avatar from your Avatars library, or upload a new reference image directly (JPG, PNG, max 10 MB). The character in this image will be animated.
4. 4Toggle 'Keep Original Sound' on or off to control whether the audio from the driving video is preserved in the output.
5. 5Click Generate. The job is queued and typically completes in 2–4 minutes.
6. 6The output video shows your avatar performing the motion from the driving video.

Best practices

• Use a clear, front-facing avatar image showing the full upper body or full body — avoid extreme orientations (upside down, lying flat)
• The driving video should feature a single person with clear, steady motion — avoid camera cuts, fast motion, or scene transitions
• Keep the driving video between 5–15 s for best results; very short or very long clips may reduce motion quality
• Trim your driving video to exactly the section of motion you want before uploading
