OBS

By connecting Livesync to OBS, you can use real-time face swaps on any platform—whether you’re streaming on Twitch, YouTube, or using it in Zoom, Google Meet, Microsoft Teams, and more.

In this guide, we’ll show you the simplest method to integrate Livesync with OBS—capturing your face swapped video and audio to stream or use in video calls.

Step 1: Install OBS & Virtual Audio Driver

Before starting, ensure you have:

✅ OBS Studio installed. Download it from obsproject.com.

✅ A virtual audio driver installed to capture system audio separately.

For different operating systems, use:

We’ll use BlackHole on macOS as an example in this guide.

Step 2: Configure Virtual Audio for OBS

Since Livesync introduces a slight video delay, capturing audio separately ensures that your voice stays synchronized with the processed video.

Set Up BlackHole (macOS Example)

  1. Open Audio MIDI Setup on your Mac.
  2. Click + (Create Aggregate Device) and select BlackHole + Built-in Output.
  3. Set this as your default system output.

For Windows/Linux, follow a similar process using VB-Audio Virtual Cable or PulseAudio to route system audio to OBS.

Step 3: Capture Livesync in OBS

To display the face-swapped video and capture the corresponding audio in OBS, you need to set up a browser source. This allows you to integrate Livesync seamlessly into your OBS setup.

Start a Backstage Session in Livesync

  1. Open Livesync in your browser.
  2. Start a Backstage session from the Streaming section.
  3. Apply your desired persona to start the face-swapped video.
  4. Click the Share icon at the end of the Video Control Panel and copy the sharing link.

Add Livesync Video & Audio Sources in OBS

  1. Open OBS and create a new Scene.
  2. Click + (Add Source) and select Browser - Create new.
  3. Enter the sharing link copied from Livesync in the URL field in the Browser Properties window.
  4. Check Control audio via OBS to ensure the audio is managed within OBS.

  1. Adjust the window size and position to frame your persona video properly.

Start OBS Virtual Camera

Before streaming or joining a video call, enable OBS Virtual Camera so that other applications can recognize the face-swapped video as your webcam.

  1. In OBS, click Start Virtual Camera (bottom-right corner).
  2. Now, OBS will output the face-swapped video to any app that supports webcams.

  3. Click Start Streaming—your face-swapped video is now live! 🎭
