How to Flip a Webcam Horizontally in OBS Studio

If your webcam feed in OBS Studio appears backward, mirroring or flipping it horizontally is a quick and simple fix. This guide provides a direct, step-by-step walkthrough on how to horizontally flip your camera source in OBS Studio using the transform settings, ensuring your text, background, and physical movements look natural to your audience.

Method 1: The Quick Right-Click Method

The fastest way to mirror your webcam in OBS Studio is through the right-click context menu.

  1. Open OBS Studio and locate the Sources dock at the bottom of the screen.
  2. Left-click on your webcam source (usually named “Video Capture Device”) to select it.
  3. Right-click on either the webcam source name in the Sources dock or directly on the webcam feed in the preview window.
  4. Hover your mouse cursor over the Transform option in the dropdown menu.
  5. Click on Flip Horizontal from the sub-menu.

Your webcam feed will instantly mirror itself horizontally.

Method 2: Using the Edit Transform Menu

If you need precise control over your source coordinates or want to manually adjust the scale, you can use the Edit Transform menu.

  1. Select your webcam source in the Sources dock.
  2. Use the keyboard shortcut Ctrl + E (on Windows) or Cmd + E (on Mac) to open the Edit Transform window. Alternatively, you can right-click the source, select Transform, and then click Edit Transform.
  3. In the Edit Transform dialog box, locate the Bounding Box Type and size settings.
  4. To manually flip the image, you can change the horizontal scale value to a negative number (for example, changing the width scale from 100% to -100% or reversing the width dimension). However, clicking the quick “Flip Horizontal” option is still the most efficient way to achieve this.
  5. Click Close to apply the changes.

How to Undo the Mirror Effect

If you ever need to revert your webcam back to its original orientation:

  1. Right-click your webcam source in OBS.
  2. Hover over Transform.
  3. Click Reset Transform (or press Ctrl + R / Cmd + R) to restore the camera to its default settings. Alternatively, clicking Flip Horizontal a second time will toggle the mirror effect off.
