How to use Liveface as an OBS source

Liveface produces the filtered video; OBS Studio captures it as a scene source and exposes the result to any other app (Zoom, Meet, Teams, Discord, Streamlabs, Twitch, YouTube Live, etc.) as a virtual camera.

  1. 01

    Open the Liveface swap page

    In a browser of your choice (Chrome / Safari / Edge / Firefox all work), sign in at liveface.app, grant webcam access, pick a target face. Confirm the live filtered video is rendering in the tab.

    TipUse a dedicated browser window for the swap so OBS Window Capture has a stable target. Window Capture sources can break if you accidentally close that tab.
  2. 02

    Add a Window Capture source in OBS

    In OBS Studio, click + under Sources → Window Capture → Create new → OK. In the dropdown, select the browser window holding the Liveface tab. The OBS preview canvas now shows the full browser window including chrome.

  3. 03

    Crop the capture to just the video panel

    Drag the corners of the capture bounding box in the OBS preview, or hold Alt and drag the edges to crop. The goal: only the swapped video appears in OBS, no browser address bar / tabs / OS chrome. This is what other apps will see when they read the OBS Virtual Camera output.

    TipFor a 16:9 output, crop to a 16:9 box matching the video aspect. The default Liveface tab includes UI sidebars — exclude those for a clean meeting/stream image.
  4. 04

    Start OBS Virtual Camera

    Click Start Virtual Camera at the bottom-right of the OBS main window. A confirmation dialog may ask which scene to use — pick the scene containing your Liveface capture.

  5. 05

    Use OBS Virtual Camera in any other app

    In Zoom / Meet / Teams / Discord / Streamlabs / Twitch Studio: open the camera selection dropdown and pick "OBS Virtual Camera". Your filtered face is now the camera input. Stop Virtual Camera in OBS when you are done to free the device.

Frequently asked

Can I add other OBS sources (text overlays, logos, alerts) on top of the Liveface feed?

Yes. Liveface is just another source in your OBS scene. Layer text alerts, watermarks, browser source widgets, logos, anything OBS supports — all on top of the swapped video.

Does OBS Virtual Camera work with hardware encoders / NVENC?

Yes. OBS Virtual Camera output is independent of the encoder you use for recording or streaming — it is a software camera device that reads from your active OBS scene preview. Encoder choice (NVENC, x264, AV1) only affects recording / streaming, not the virtual camera output.

Can I use Liveface in Streamlabs Desktop instead of OBS Studio?

Yes. Streamlabs Desktop is OBS-based and has the same Window Capture + Virtual Camera flow. Source naming is identical.
