How to Face Swap a Video with Haotian AI
A complete step-by-step guide — swap faces in any video in under 3 minutes.
Video face swapping used to require expensive software and hours of manual editing. With Haotian AI, you can swap a face in a video in a few clicks, and the result looks natural — the AI matches lighting, skin tone, and head movement across every frame. Here's exactly how to do it.
What you'll need
- Haotian AI installed (Windows, macOS, Linux, Android, iOS) or the cloud app in your browser.
- The video you want to edit.
- A clear photo of the face you want to swap in.
Step-by-step: face swap a video
1. Open Haotian AI
Launch the app (or open the cloud version) and start a new video project.
2. Upload your video
Drag in the clip you want to face swap. Shorter clips process fastest, but Haotian AI handles full videos too.
3. Choose the new face
Upload a photo of the face you want to use. A front-facing, well-lit photo gives the most realistic result.
4. Run the swap
Haotian AI detects and tracks the face through every frame, then blends the new face in. Most clips finish in seconds to a couple of minutes.
5. Export in HD
Preview the result, then export in HD (or 4K on the lifetime license). Share it to TikTok, Reels, or anywhere.
Tips for a realistic video face swap
- Use a high-resolution source face photo.
- Match the angle — a front-facing face photo works best for front-facing videos.
- Good lighting in the original video improves blending.
- For multiple people in frame, pick exactly which face to replace.
