Live face swap on Windows: browser setup guide

What today's Windows setup actually needs

On Windows, real-time face swap runs in the browser. You need Windows 10 or 11, a current version of Chrome or Edge, a webcam, and an internet connection that can carry video both ways. There is no GPU requirement, no installer and no administrator permission to ask for, because the model runs in a cloud session on LiveFaceSwap V1.

Create an account if you have not already. New accounts get 10 free credits, and one live second costs 0.6 credits, so the free balance covers a quick test of the whole flow before you buy a pack.

Open the studio and allow the camera

Open the live studio in Chrome or Edge, then press Open camera. The browser shows a permission prompt for the camera; choose Allow. If you dismiss the prompt by accident, the camera will stay blocked until you change the setting for the site.

Check that the right camera is selected. A laptop with a USB webcam may expose two devices, and Windows sometimes keeps a virtual camera from a call app at the top of the list. The studio uses the browser's default camera, so if the wrong one opens, change the default camera in Windows Settings (or in the browser's site settings) and reload before pressing Open camera again.

Fix camera access when the preview stays black

• Open Windows Settings, then Privacy and security, then Camera. Make sure camera access is on and that Let desktop apps access your camera is on as well; Chrome and Edge are treated as desktop apps.
• In Chrome or Edge, open the site information panel from the address bar and set Camera to Allow, then reload the page.
• Close Teams, Zoom, Discord and any other tab or app that might be holding the camera. Only one app can use a webcam at a time.
• Check the privacy shutter or the hardware switch on the webcam itself, and make sure the webcam appears in Device Manager without a warning icon.
• If the camera works everywhere except the browser, update the browser, then the webcam driver. Some corporate Windows images block cameras through group policy, and that has to be changed by whoever manages the machine.

When the live output stutters

The model runs remotely, so the path between your PC and the internet matters more than the graphics card. A wired Ethernet connection or a 5 GHz Wi-Fi signal gives the most stable upload; 2.4 GHz Wi-Fi, a busy network or a VPN can add delay and jitter.

Close what you do not need: other video calls, cloud sync during large uploads, and heavy game downloads all compete for the same connection. In the browser, keep the studio as the only tab using the camera and let hardware acceleration stay on, since the decoder is what draws the incoming video.

Capture the swapped video for OBS or a stream

Today the output lives in the browser tab, so a Windows stream or recording takes one extra step: add a Window Capture source in OBS, select the browser window that holds the studio, and crop away the browser chrome. Audio does not come from the studio; capture your microphone as a separate OBS source. The OBS guide walks through the full scene setup.

If you only need to show the result in a quick call, sharing the browser window is faster than building an OBS scene.

There is no Windows desktop app yet

The browser studio is the whole product on Windows today. A desktop app is planned, and it is intended to add a system virtual camera so OBS, Zoom, Teams and Discord can select the swapped video as a camera instead of a shared window. It is not available yet, so do not plan a workflow that depends on it: the desktop page tracks the plan and will say when there is something to download.

Limits to know before a long session

A single live session stops at 900 seconds (15 minutes), which is a provider limit rather than a browser one. Streaming for longer means starting a new session after each cap. Each live second is billed at 0.6 credits, and stopping a session returns the unused part of the reservation, so short sessions are efficient.

The camera stream is not recorded. You still need to be 18 or older, hold the rights and consent for any face you use, and tell viewers that the video is AI-generated.
