How to swap a face into a video
Face swap does one narrow thing well: it keeps the camera framing, the background and the performance, and changes who the face belongs to. That is a different job from making someone from scratch, and a smaller one — which is also why it is cheaper to get wrong and cheap to test.
Open the AI Face SwapStep by step
- 1
Upload the source video
MP4, MOV or WebM. A stable, front-facing shot of the original face gives the model the clearest job to do.
- 2
Upload the reference face
A clear, front-facing, well-lit photo. Side angles, sunglasses or a second face in frame all make the result worse.
- 3
Set the real length
Duration is what the job is priced on. Enter the true length of the clip you uploaded.
What makes the difference
- A face that is mostly forward-facing throughout the clip swaps far more cleanly than one that turns in profile for long stretches.
- Test on a short clip before committing to a long one — 20 credits a second adds up fast on a bad take.
- Only use this on footage and faces you own the rights to, or have explicit consent for. This tool changes who appears to be saying and doing something on camera.
Questions
Does it change anything besides the face?
No. Camera movement, background, body motion and audio are all kept from the source video.
What if I want the hair and outfit to change too, not just the face?
Use Person Replace instead — it swaps the whole person, not only the face.
How much does a 10-second clip cost?
20 credits per second, so 200 credits — a little over the free signup allowance.
