How to Stream Multiple Cameras in OBS Studio

Streaming a live concert with multiple camera angles elevates the production value and keeps your audience engaged. This guide will walk you through the essential steps to connect multiple cameras to OBS Studio, configure your scenes, sync your live audio, and switch between angles seamlessly during a high-energy music performance.

1. Connect Your Cameras to Your Computer

To stream multiple angles, you need to connect your cameras to your streaming PC. While you can use USB webcams, professional concerts benefit from DSLRs, mirrorless cameras, or camcorders. * Use Capture Cards: Connect each camera via HDMI into an individual USB capture card or a multi-input PCIe capture card (like a Blackmagic DeckLink) installed in your PC. * Manage USB Bandwidth: Avoid plugging all USB capture cards into the same USB hub, as this can overload your motherboard’s USB controllers and cause lag. Distribute them across different USB ports.

2. Set Up Individual Scenes in OBS Studio

Once your hardware is connected, launch OBS Studio and create a dedicated scene for each camera angle. 1. In the Scenes box, click the + icon and name your first scene (e.g., “Wide Shot”). 2. In the Sources box for that scene, click the + icon and select Video Capture Device. 3. Name the device, select your respective capture card/camera from the device dropdown menu, and click OK. 4. Repeat this process by creating new scenes for your other angles (e.g., “Close-up Singer,” “Drum Cam”) and assigning the correct video source to each.

3. Sync Audio to Video (Crucial for Concerts)

In live music streams, audio and video synchronization is critical. Because video capture cards introduce a slight processing delay, your audio will often play before the video. 1. Connect your concert audio feed (from a mixing console or audio interface) to OBS as an Audio Input Capture source. 2. Click the gear icon next to your audio source in the Audio Mixer and select Advanced Audio Properties. 3. Adjust the Sync Offset (usually between 50ms and 250ms) for your audio source. You can test this by recording a short clip of a drum hit or handclap and adjusting the offset until the sound matches the visual impact.

4. Switch Cameras Smoothly Using Studio Mode

To manage a live concert broadcast professionally, use OBS Studio’s built-in switching features. * Enable Studio Mode: Click the Studio Mode button above the control panel. This splits your screen into “Preview” (on the left) and “Program” (on the right, which is what the viewers see). * Prep and Transition: Click on any scene to queue it up in the Preview screen, then click Transition (or use the fade slider) to push it live. * Configure Hotkeys: Go to Settings > Hotkeys to assign keyboard shortcuts to each scene. Alternatively, integrate a physical macro controller like an Elgato Stream Deck to switch camera angles at the press of a physical button.
