Duplicate OBS Camera Feeds Using Source Mirror

This article explains how to duplicate a camera feed in OBS Studio using a third-party “Source Mirror” or “Source Clone” plugin, allowing you to apply different filters to each feed independently. You will learn how to install the necessary plugin, create a cloned source, and configure unique filters for creative broadcasting setups.

Step 1: Install a Source Mirror Plugin

To duplicate a source with independent filters in OBS Studio, you need a third-party plugin. The most reliable and up-to-date option is the Source Clone plugin by Exeldro (frequently referred to as Source Mirror).

  1. Visit the OBS Projects forum and search for the Source Clone plugin.
  2. Download the installer compatible with your operating system (Windows, macOS, or Linux).
  3. Close OBS Studio, run the installer, and then restart OBS Studio.

Step 2: Set Up Your Original Camera Source

Before mirroring, ensure your primary camera is active in your scene.

  1. In the Sources dock, click the + icon.
  2. Select Video Capture Device and choose your camera.
  3. Position and configure this camera as your primary, clean feed.

Step 3: Create the Cloned Source

Now you will create the duplicate feed that behaves independently of the original camera layer.

  1. In the Sources dock, click the + icon.
  2. Select Source Clone from the list.
  3. Name the new source (e.g., “Camera - Blurred” or “Camera - Black & White”) and click OK.
  4. In the properties window, locate the Clone Source dropdown menu.
  5. Select your original Video Capture Device (your camera) from the list.
  6. Click OK. You will now see an exact duplicate of your camera feed on your canvas.

Step 4: Apply Independent Filters to the Duplicate

Because the cloned source is treated as a separate entity by OBS, any filters applied to it will not affect the original camera feed.

  1. Right-click on your newly created Source Clone in the Sources dock.
  2. Select Filters.
  3. Click the + icon under the Effect Filters section.
  4. Add your desired filter, such as Color Correction (to change contrast, saturation, or color), Chroma Key, or a Blur filter.
  5. Adjust the filter settings to your liking and close the window.

You now have two active feeds of the same physical camera running simultaneously in OBS Studio, each displaying its own distinct visual style.
