Live face swap in Zoom, Meet and Teams calls
How to show real-time face swap in a video call today with window share or OBS, the disclosure rules, audio setup, and the limits of screen sharing.
The honest short answer
There is no LiveFaceSwap virtual camera yet, so Zoom, Meet and Teams cannot select the swapped video as a camera device. There are two supported ways around that today: share the browser window that shows the live output, or capture the studio in OBS and let OBS's own virtual camera carry it into the call. Neither is hidden magic, and both need a decision about disclosure before the call starts.
What the other side will see
With window sharing, the other participants see a shared screen or window, not a camera tile. It works in the main call and in a presentation layout, but it takes a piece of the layout and it is obvious that something is being shared. With the OBS route, the call app receives a normal camera feed, so the swap appears exactly where your face normally does, which is a better fit for one-to-one calls and panel layouts.
Pick the route to match the call. Window sharing is faster to set up and harder to abuse unnoticed; the OBS camera route looks natural, so the disclosure obligation matters more.
Option A: share the browser window
- Zoom desktop app: Share Screen, choose Window, select the browser window that holds the studio, then share. Stop sharing before you stop the session.
- Google Meet in Chrome: Present now, choose A window, pick the studio window. Window sharing keeps the rest of your desktop private.
- Microsoft Teams desktop app: Share, choose Window, pick the studio window. If the meeting is recorded, the shared window is recorded too.
- Keep the studio window at a readable size and avoid overlapping windows. Resizing the window during a call distorts the shared frame.
Option B: use OBS's virtual camera
Capture the studio in OBS as described in the OBS guide, then press Start Virtual Camera in OBS. The call app will now list OBS Virtual Camera as a camera option: in Zoom it is Settings, then Video, then Camera; in Google Meet it is Settings, then Video, then Camera; in Teams it is Settings, then Devices, then Camera. Discord lists it under User Settings, then Voice and Video.
That virtual camera belongs to OBS, not to LiveFaceSwap.co. It works because OBS is already receiving the studio's video. A dedicated LiveFaceSwap virtual camera is planned to ship with the desktop app, which is not available yet.
Disclose it, every time
Real-time face swap is an effect, not a disguise. Tell the other people in the call that the face they see is AI-generated, ideally before the call or in the first minute. Use only your own face, or a face you have explicit consent to use, and remember that a video call may be recorded by someone else.
The studio asks you to confirm you hold the rights and consent for the reference image and that you will not use it to impersonate or deceive anyone; the acceptable-use policy it links to applies in calls as well: no impersonation, no deceiving someone who has not agreed, no using a public figure's face. Many workplaces restrict synthetic video in meetings, and in some places undisclosed synthetic media is illegal, so a work call is not the place to test the boundaries.
Audio and session limits
The studio produces video only. Your microphone continues to go to the call app directly, and with the OBS route it goes to OBS as an audio source, so keep the same audio path you would normally use.
A live session stops at 900 seconds. For a longer call, start a new session when the cap hits and reselect or re-add the shared window if needed. Each live second costs 0.6 credits, and credits are reserved when the session starts and settled when you press Stop; unused reservation comes back.
If the shared video looks soft
Video calls recompress whatever they receive, so a shared window will not look as sharp as the studio in a full browser tab. Share the window rather than the whole screen, keep the studio output as large as the window allows, and light your face well so the model has clean input.
If the call lags, the cause is usually the upload path: the studio already sends frames to the cloud and back, and the call app sends the result onward. A wired connection or a strong 5 GHz signal helps both hops at once.
FAQ
- Is there a LiveFaceSwap virtual camera for Zoom?
- Not yet. The browser studio does not register a system camera. A dedicated virtual camera ships with the planned desktop app; today OBS's own virtual camera is the cleanest way to appear in a camera tile.
- Can I use face swap in a work meeting?
- Only if you disclose it and everyone involved is comfortable with it. Many workplaces ban synthetic video in meetings, and passing a generated face off as yourself can breach policy or law. It is not appropriate as a way to mislead a colleague or client.
- Why does the call lag more than the studio preview?
- The frames already travel to the cloud model and back before the call sends them on. Anything that slows the upload path, such as weak Wi-Fi or a busy network, adds delay in the call and in the studio at the same time.
