The trend is everywhere: a viral clip plays exactly as before, but the person in it is now you. Modern AI face swap models replace the people in a video while keeping the scene, the camera moves and the original sound. Here’s how to do it well, what it costs, and the rules you shouldn’t break.
Two kinds of video face swap
| Type | What it does | Best for |
|---|---|---|
| Recast (replace in place) | Swaps the people in the clip and keeps the scene and audio | Trends, skits, reaction clips |
| Motion transfer | Your photo performs the clip’s movement | Dances, single-person moves |
Step by step
- Pick the clip. 5–30 seconds, one or two clearly visible people, no single shot longer than about 15 seconds.
- Take a good selfie. Front-facing, even light, no sunglasses, face filling a good part of the frame.
- Confirm consent. Only your own face, or someone who has agreed. No minors, no public figures.
- Check the price, then run it. A swap takes a few minutes.
- Finish it: trim, reframe to 9:16, add captions.
In Claude or ChatGPT
Prompt[attach selfie] Put me in this TikTok instead of the dancer: [link]. Use 768p and the first 6 seconds. Show me the price first.
The assistant imports the clip, checks its shots, quotes the credits and waits for your yes. The result shows in the chat and is saved to your library with an “AI-generated” label.
What it costs
Face swaps are priced per second: on Typeshoot, 60 credits a second at 768p and 90 at 1080p (motion transfer is 34). A 5-second test at 768p is 300 credits; start there before doing a longer clip.
Getting a better result
- Choose clips where the face is large and well lit; tiny or turned-away faces swap poorly.
- Avoid fast cuts in the first try; a single continuous shot is most stable.
- Match roughly: similar hair length and face shape look more natural.
- Use 768p for tests and 1080p for the version you post.
The rules: consent, labels and copyright
- Consent: Typeshoot asks you to confirm it before every swap.
- No minors or public figures, in any context.
- Label it: TikTok, YouTube and Instagram require labels for realistic AI-altered video. Typeshoot marks swaps visibly and in the file’s metadata.
- The source clip belongs to its creator. Personal, transformative use is one thing; passing their performance off as yours is another.

Is it legal to face swap a video?
Swapping in your own face, or someone who agreed, for personal or creative use is generally fine. Using someone else’s face without consent, minors, sexual content or content meant to deceive can be illegal and breaks most platforms’ rules.
How long can the video be?
Most face swap models work on 5–30 second clips, with each continuous shot under about 15 seconds. Longer videos can be trimmed first.
Does it keep the original audio?
Recast-style swaps keep the scene and the original sound and only replace the people.
How much does a face swap cost?
With Typeshoot, 60 credits per second at 768p or 90 at 1080p, so a 5-second test is 300 credits.
