Generate the complete edit

Clear inputs, fixed roles, honest limits.
The workflow keeps the source performance intact while giving you control over character identity and output detail.
Your cast
One lead plus five optional supporting references, each assigned to one stable role.
Output detail
Use 480p for tests, 720p for most posts, or 1080p for a final render.

What to know before rendering.
Review the output carefully. AI video can drift during fast motion and crowded scenes.
Can I generate with only one photo?+-
Yes. Add only a lead photo and the model will keep the source supporting cast. Extra character photos are optional.
How are supporting people assigned?+-
References follow first appearance order. When several people appear together, the source scene order determines their roles.
Does this only swap faces?+-
No. Seedance edits the complete person, including hair, clothing, body shape, and visible accessories. Fine logos and small details may change.
Why are photos reviewed first?+-
APIMart requires real human faces to pass Private Avatar review. Approved private assets are then used by Seedance.
Will every identity remain perfect?+-
No model can guarantee that. Fast motion, occlusion, profile views, hands over faces, and crowded shots can introduce drift or mixed identities.
Does the result include music?+-
The edit asks Seedance to preserve the source soundtrack. Use and publish it only when you hold the necessary rights, and review the finished audio before downloading.
Start with one clear portrait.
Purchase a credit pack before your first render. Credits do not expire.
