How do I swap faces in AI video?
Short answer
Upload a clear source face photo and the target video, use a dedicated video face swap tool to map facial landmarks, preview the result for alignment accuracy, and export once the swap looks natural.
Recommended mode: DirectorScenario: Replacing a placeholder actor face with the intended talent in an AI-generated commercial draft, ensuring the swap blends naturally with expressions and lighting.
Execution Steps
- 1Select a high-quality, well-lit source face photo with a neutral or matching expression to the target video.
- 2Upload the target video clip and source face image to a video face swap tool.
- 3Let the tool analyze facial landmarks and generate the initial swap preview.
- 4Review the preview frame by frame, paying attention to jawline blending, skin tone matching, and expression transfer.
- 5Adjust blending parameters such as face boundary softness and color correction, then render the final output.

- Expecting perfect results on profile or extreme angle shots where facial landmarks are partially hidden
