How to Use Live Face Swap in OBS for Streams and Video Calls
Updated · By the AI Face Swap Live team
Quick answer
Open AI Face Swap Live in Chrome, start a live swap, and keep the live result visible in its own browser window. In OBS Studio, add a Window Capture source for that window and crop it to the result. To stream, go live from OBS. For Zoom, Google Meet or Discord, click Start Virtual Camera in OBS and choose "OBS Virtual Camera" as your camera in the call.
What you need
- A Windows or Mac computer with a webcam
- Chrome or Edge
- OBS Studio, free from obsproject.com
- One clear, front-facing portrait of the face you want to use
- Live minutes on your AI Face Swap Live account (pricing)
Set it up in 5 steps
- 1
Start a live swap in its own browser window
Open aifaceswaplive.net in Chrome or Edge, upload your portrait, turn on your camera and press Start live swap. Keep the studio in a separate browser window, so OBS can capture it while you use other tabs. Make the window big enough that the live result fills most of it.
- 2
Add the window to OBS
In OBS Studio, click + under Sources and choose Window Capture. On a Mac, choose macOS Screen Capture and set Method to Window Capture. Pick the Chrome or Edge window that shows the live result.
- 3
Crop to the live result
Hold Alt (Option on a Mac) and drag the edges of the source to cut away the browser bars and your own camera preview. You can also right-click the source, open Filters, and add a Crop/Pad filter with exact pixel values.

Add your microphone
The swap changes your video only. Keep the Mic/Aux source OBS creates by default, or add an Audio Input Capture source for your microphone.
- 5
Stream, or start the virtual camera
To stream, paste your Twitch, YouTube or TikTok LIVE stream key in Settings, Stream, and click Start Streaming. For a video call, click Start Virtual Camera in the Controls panel. Then open the video settings in Zoom, Google Meet, Discord or Teams and choose OBS Virtual Camera.
Fix common problems
The Window Capture source is black on Windows
Right-click the source, open Properties, and set Capture Method to "Windows 10 (1903 and up)". If it stays black, turn off "Use graphics acceleration when available" in Chrome under Settings, System, then restart Chrome.
OBS shows nothing on a Mac
Open System Settings, Privacy & Security, Screen & System Audio Recording (Screen Recording on older macOS), allow OBS, and restart OBS.
The call shows a mirrored or frozen picture
Zoom and Meet mirror only your own preview, so other people see you the right way round. If the picture freezes, stop and start the virtual camera in OBS, then select it again in the call.
The swap looks soft or lags
Close other uploads and video tabs, move closer to a window or lamp, and use a wired connection if you can.
Use it fairly
Tell people they are watching a swapped face when it matters to them. Never use a swap to pass an ID check or to pose as a real person in a call. The full rules are under Safety and consent.
FAQ
Does AI Face Swap Live have its own virtual camera?
No. You use the virtual camera built into OBS Studio, which is free for Windows, Mac and Linux.
Will people in my video call see the swapped face?
Yes, once you pick OBS Virtual Camera as your camera. They see whatever the OBS canvas shows, so crop the source to the live result only.
Does the swap change my voice?
No. Your microphone audio stays your own voice. Add it in OBS as a separate audio source.
How much does an hour of streaming cost?
$29.99 with the 60-minute pack, or about $16.00 with the 300-minute pack. We count by the second, only while the swap runs.
