- Prepare clean speech audio with the exact script.
- Write a short behavior prompt: tone, expression and natural movement.
- Generate the clip, then reuse the same portrait for more scripts.
FAQ

One portrait image URL, one speech audio URL and a prompt for expression or behavior.
Is the helper detection tooling a video model?
No. The Studio route is the video generation route; detection helpers are separate checks and are not exposed as video models.
