Create with Face Swap VideoHow this tool works
Face Swap Video, with the inputs and limits made clear
Use one reference portrait to guide the face identity of a person in a short source video while retaining the original performance and scene.
What to provide
- One source videoUpload the performance clip whose movement, expressions, and framing should drive the result.
- One face reference imageUpload a clear portrait that provides the face identity for the visible person.
Steps
- Upload one source video containing the person to be transformed.
- Upload one clear face reference image with a usable view of the target identity.
- Run the reference-guided video workflow using the source performance and portrait.
- Inspect identity stability through head turns, expressions, hair, and changing light.
What to expect
- One video that follows the source performance with a reference-guided face identity.
- The original expressions, head movement, clothing, lighting, camera, and background should remain part of the shot.
- Identity consistency is expected across frames but is not a guarantee under every angle or occlusion.
Where results can vary
- A reference portrait with a hidden face, extreme angle, or poor lighting gives the workflow less usable identity information.
- Fast head turns, hands over the face, hair crossing facial features, and multiple faces can cause drift or blending artifacts.
- The source video must be 15 seconds or shorter; this workflow is not designed for a long-form face replacement edit.

Questions before you run it
Face Swap Video FAQ
What does face swap video require?
It requires one source video and one face reference image. The video supplies the performance; the image supplies the face identity.
Will the reference portrait change the clothing or background?
The configured workflow uses the portrait for face identity and aims to retain the source video’s clothing, lighting, camera, and background.
Why can a face drift during a swap?
Extreme angles, occlusions, motion blur, changing light, and several similar faces reduce the visual evidence available for stable frame-to-frame guidance.
