From upload to download
How to use Change Face in Video
Face swap video online with a short MP4 and one reference photo.
Start with a short clip
For AI video face swap, upload an MP4 up to 60 seconds and 100 MiB. Choose a short, steady scene first; it is quicker to review and costs fewer credits.
Add a reference portrait
Add a clear adult portrait. To replace face in video, the tool automatically uses the largest detected face; a single-person clip gives you a clearer starting point.
Watch, compare and download
Review your face swap on video at normal speed and pause around turns or occlusions. Compare it with the original before downloading the completed clip.
A better starting point
The right reference makes a difference.
Before you face swap video online, look at the reference and the clip together. Similar angles and clear facial detail help the model; fast cuts and heavy motion blur make the task harder.
Keep the face in view
Choose a sharp adult portrait with visible eyes and a clear jawline. Skip sunglasses, heavy filters and hands over the face.
Match the angle
A similar head angle gives the model a better starting point. Strong profiles and extreme tilts are harder to match.
Look for soft, even light
Use a well-lit face with natural skin detail. Deep shadows and motion blur can make the result less consistent.
Clear before you create
A clear price. Your choice.

How we handle your filesA few things worth knowing
Your questions, answered.
Before you use Change Face in Video, check the clip limits, billing and what to look for in playback.
What do I need to use Change Face in Video?
Upload an MP4 original and a JPG, PNG or WebP reference portrait up to 15 MiB. You can face swap video online in the browser; use adult faces and footage you have permission to edit.
Which video formats and sizes are supported?
Use MP4 with H.264 video, up to 60 seconds and 100 MiB. The long edge must be at most 1920 pixels, at up to 30 fps. Audio can be AAC, or the clip can have no audio.
How much does a video face swap cost?
The rate is 5 credits per billed second, rounded up, with a 3-second minimum. A 2-second clip costs 15 credits; a 10-second clip costs 50. There are no Standard and Pro video tiers.
Can I replace face in video clips with several people?
The tool automatically replaces the largest detected face, without manual person selection. Movement, changes in face size or scene cuts can cause it to replace a different person. Single-person clips are recommended.
What should I check after a face swap on video?
Watch the whole clip, including head turns and moments when hands cross the face. Check facial edges, expressions and the original audio if present. The service is not a voice replacement tool.
Can I select 2K or 4K output?
There is no output-resolution selector. Supported input dimensions do not imply guaranteed output resolution. Check the downloaded file and the complete visual result before using it in your edit.
What happens if processing fails?
Technical failures release the reserved credits. Tasks continue if you close the page; return with the same account to check status. Completed files are stored privately for 7 days and can be deleted sooner.
