Pro Tips
- Use a high-quality, well-lit face photo with a clear, unobstructed view for the most natural compositing result.
- Videos with a single clearly visible subject and stable lighting produce the cleanest swaps.
- Avoid heavily cropped or low-resolution face images — the more facial detail the AI has, the better the blend.
- For best results, the face in the image should be roughly front-facing and similar in angle to the subject in the video.
