FAQ
What to know before uploading your clip.
Can I change a face expression in a video with AI?
Yes, in your own or authorized footage. Keep the prompt focused on a natural expression change while preserving identity.
Is this an identity swap tool?
No. Identity swaps, celebrity edits, and impersonation are not supported.
Why is the prompt so specific?
