01What person swap does
You upload a short clip and one photo. Seedance 2.5 keeps the original motion, camera moves and timing, and replaces the person with the one in your photo. It is the same technique behind our trend remakes.
02Your clip
- 4 to 15 seconds, MP4 or MOV, up to 50 MB
- One person, clearly visible for most of the clip
- Steady light and little motion blur
- No crowds crossing in front of the face
03Your photo
- One person, facing the camera
- Similar light to the clip if you can
- Only people who agreed to be swapped in
04What it costs
Seedance bills your clip plus an output of the same length, so the price follows the measured length of your upload. The exact number appears as soon as the clip is uploaded.
| Clip length | 480p | 720p |
|---|---|---|
| 5 s | 231 | 519 |
| 10 s | 461 | 1,037 |
| 15 s | 692 | 1,556 |
05Ask first
Swapping someone into a video changes what they appear to do. Only use clips and photos you have permission to use, and never use it to mislead. You confirm this before every swap.
