LiveFaceSwap Desktop processes your camera feed on Windows and exposes the AI result as a virtual camera named LiveFaceSwap Camera. Use it when you want to send the transformed feed to OBS; use the online workspace when you only need an interactive browser preview. Because camera devices and receiving apps can behave differently, test the full path before broadcasting or joining a call.
The app logos in this concept image illustrate the routing idea only. They are not compatibility certification for every app or version.
1. Check Windows Requirements and Install Desktop
LiveFaceSwap Desktop requires 64-bit Windows 11 build 22000 or newer. Download the Windows installer from LiveFaceSwap Desktop, then approve the Windows User Account Control (UAC) prompt.
The installer automatically registers LiveFaceSwap Camera; there is no separate registration button after installation. If the installer reports that the camera could not be updated, close applications using a camera, follow the installer prompt, and retry.
2. Set Up the Input Camera, Model, and Reference
Open the app and choose Sign in. In Input camera, select the physical camera that should provide the source video, such as your built-in webcam or connected USB webcam. This is the input to LiveFaceSwap Desktop; it is not the virtual camera that another application will select later.
Under Effect, choose Face Swap. Then choose a Model, review the displayed credit rate, and add a permitted portrait under Reference. Use only a reference and camera feed that you own or are authorized to use, and disclose synthetic or altered video where it could otherwise mislead viewers.
Before enabling the camera or adding a reference, review the Privacy Policy for the current data-processing and retention terms.
This screenshot shows the current Desktop controls with example camera, account, rate, and preview values. It does not show a completed AI or OBS session.
3. Add LiveFaceSwap Camera in OBS
In OBS, click + under Sources, choose Video Capture Device, create or select the source, then choose LiveFaceSwap Camera from the Device list.
If the device is missing, use the matching recovery steps under Troubleshooting below.
4. Start Live and Confirm the Output
Select Start Live after checking the camera, effect, model, reference, rate, and OBS source. Wait until the status and preview show transformed frames; clicking Start Live alone does not confirm a successful session.
Billing starts after the first confirmed AI frame. If transformed frames do not appear, choose Stop before troubleshooting. After stopping, wait until the app reports Live session stopped before changing settings or starting again.
When the session is connected and the virtual-camera output is available, keep the two devices distinct:
- Input camera is your physical source device inside LiveFaceSwap Desktop.
- LiveFaceSwap Camera is the virtual output device selected in OBS.
Confirm that both the Desktop preview and OBS source show the transformed frames before broadcasting.
Choose Stop when you finish. LiveFaceSwap Desktop provides live video output; it does not record, download, or export the session. If you need a recording, configure that separately in OBS or another receiving application. LiveFaceSwap Camera is a video device, so configure your microphone or other audio sources separately in OBS.
Optional: Test LiveFaceSwap Camera in Other Apps
Other streaming, meeting, recording, or video-call software may show LiveFaceSwap Camera in its camera-device picker. Support varies by software and version, so test the device before joining a call or using it in production.
Troubleshooting
The Camera Preview Is Blank
First, make sure the correct physical camera is selected under Input camera. If LiveFaceSwap says camera access is blocked, allow camera access in Windows Settings. If the camera is in use or not responding, close any other apps using it, reconnect the camera, and try again.
No AI Output Appears After You Click Start Live
If the AI output is still blank after one minute, click Stop to end the current session. Make sure the camera preview is working, confirm that a reference image and AI model are selected, and check the network connection before clicking Start Live again. The processed video should appear in the Desktop AI output before you continue to OBS.
OBS Cannot Find LiveFaceSwap Camera or Shows No Video
- LiveFaceSwap Camera is missing from the Device list: close and reopen OBS. If it is still missing, close any other apps using a camera and rerun the LiveFaceSwap installer. Follow the same steps if the installer says the camera could not be updated.
- The device is listed, but the video is blank or frozen: click Stop, then reselect LiveFaceSwap Camera in OBS. If that does not restore the video, restart OBS and click Start Live again. Check that processed video is visible in both LiveFaceSwap Desktop and OBS.
If the problem keeps coming back, open App & updates from the account menu and check for updates. Then choose Open logs to open the local logs folder. Email the logs and the message shown in the app to support@livefaceswap.ai so we can tell whether the problem is related to installation, the camera device, the live session, or the network connection.
