How to Use OBS Virtual Camera with Photo Booth Software

By the end of this guide, you will have a working OBS Studio production scene feeding seamlessly into your capture station on Windows, allowing you to capture high-impact visuals without hardware capture cards locking up your software pipeline.

Prerequisites and System Setup on Windows

Before launching your setup on-site, verify that your computer meets the performance demands of running real-time video compositing alongside your capture system. Video processing requires adequate headroom to prevent dropped frames during active sessions.

• Operating System: Windows 10 or Windows 11 (64-bit). Virtual Camera routing in this configuration is dedicated to Windows booth setups.
• Software: Latest version of OBS Studio installed, along with AI Photo Booth Pro.
• Video Capture Hardware: Your connected DSLR, mirrorless camera via HDMI capture, photobooth webcam, or external video switcher connected via USB.

Step-by-Step: Setting Up Your Scene and Virtual Camera in OBS Studio

To use OBS as a virtual camera source, you must first construct your visual canvas inside OBS Studio before pushing the feed out to your booth application.

1. Create Your Video Canvas

Open OBS Studio and head to Settings > Video. Match your Base (Canvas) Resolution and Output (Scaled) Resolution to your target photo booth aspect ratio (such as 1920x1080 for landscape or 1080x1920 for vertical kiosk displays). Set the Common FPS value to 30 or 60 fps for smooth previews.

2. Add Video Sources

Under the Sources panel, click the + button to add your video input device (such as your capture card or USB webcam). Layer your transparent PNG frames, animated media overlays, or browser source alerts above the video layer in the source hierarchy.

3. Start the Virtual Camera

Navigate to the Controls dock on the bottom right of the OBS interface. Click Start Virtual Camera. OBS will now broadcast its active program output as a DirectShow video device across your Windows system.

Connecting OBS Virtual Camera Inside AI Photo Booth Pro

Once OBS is outputting the virtual signal, you can select it directly inside your photo booth software just as you would any connected physical camera.

Follow these steps inside AI Photo Booth Pro:

1. Open your active event from Event Management or launch the event settings editor.
2. Navigate to the Camera tab within Event Settings.
3. Under the Add Camera section, open the camera source selection dropdown.
4. Select OBS Virtual Camera from the list of available devices.
5. Check your live preview window. Adjust rotation, mirroring, or display scaling inside the camera settings panel to ensure your framing matches the output canvas.

Troubleshooting Latency, Resolution, and Camera Detection Issues

Running two real-time video programs simultaneously requires proper configuration to avoid common operational errors:

• Virtual Camera Not Appearing: If the booth app does not list OBS Virtual Camera, close AI Photo Booth Pro, ensure Virtual Camera is started inside OBS Studio, and relaunch the booth software. Always start the OBS output before launching the capture software.
• Output Aspect Ratio Distortion: Ensure the resolution set in OBS Video Settings matches the orientation configured in your booth templates. If you are using a vertical setup, rotate your base canvas inside OBS rather than relying solely on software-side stretching.
• Video Preview Lag: Check Windows GPU utilization. In Windows Power Options, ensure high-performance mode is active. In OBS, disable preview rendering on the main monitor if you are running heavy animated source files on lower-spec booth PCs.
