How to Record Video with OBS Studio on a Mac

OBS for Recording vs. Streaming on Mac

Most OBS tutorials focus on live streaming. Recording is different — you are capturing a local file, not sending data to Twitch or YouTube. This distinction matters because the optimal settings for recording are different from streaming settings, and on Mac, OBS has a few quirks worth knowing before you hit that Record button for the first time.

After coaching dozens of course creators and YouTubers through their first OBS setup on Apple Silicon and Intel Macs alike, here is the exact setup sequence that works reliably.

Step 1: Install OBS and Grant macOS Permissions

Download OBS Studio from obsproject.com — always use the official site, not a third-party download. The current release supports both Apple Silicon (M-series) and Intel Macs natively.

On first launch, macOS will prompt you for Camera and Microphone access. Grant both. If you accidentally denied them, go to System Settings → Privacy & Security → Camera and Microphone and enable OBS there. Without these permissions, your sources will appear as black screens or produce no audio.

Step 2: Understand Scenes and Sources

OBS organizes everything into Scenes and Sources:

• A Scene is a layout — think of it as a camera setup. You might have a "Talking Head" scene, a "Screen Share" scene, and a "Talking Head + Screen" scene.
• A Source is an element within a scene — your webcam, your screen, a microphone, an image overlay, etc.

For a basic recording setup you need at least one scene with two sources: a Video Capture Device and an Audio Input Capture.

Step 3: Create Your First Scene

1. In the Scenes panel (bottom left), click the + button.
2. Name it something descriptive like "Webcam Recording" or "Tutorial Setup."
3. Click OK.

Step 4: Add a Video Capture Device Source

1. In the Sources panel, click + → Video Capture Device.
2. Name it (e.g., "Webcam") and click OK.
3. In the properties dialog, select your camera from the Device dropdown. If your camera does not appear, check macOS privacy permissions.
4. Set Resolution to your camera's native resolution (typically 1920×1080 for a 1080p webcam).
5. Set Frame Rate to 30 FPS for standard recording or 60 FPS for high-motion content.
6. Click OK. You should see a live preview of your camera in the canvas.

Step 5: Add an Audio Input Source

1. In the Sources panel, click + → Audio Input Capture.
2. Select your microphone from the Device dropdown.
3. Click OK.
4. In the Audio Mixer panel, watch the level meter on your mic source while speaking. It should peak between −12 dB and −6 dB. If it peaks in the red (0 dB), lower the gain — right-click the source and select Properties, or use the volume slider in the Audio Mixer.

Step 6: Configure Output Settings for Recording

This is where most guides miss the Mac-specific details. Go to OBS → Settings → Output:

• Set Output Mode to Advanced for more control.
• Click the Recording tab.
• Type: Standard
• Recording Path: Choose your desired folder (Desktop works fine for testing).
• Recording Format: Use mkv for recording (safer — if OBS crashes the file is not corrupted), then re-mux to MP4 after. Alternatively use mp4 directly if you do not want a remux step.
• Encoder: On Apple Silicon Macs, select Apple VT H264 Hardware Encoder or Apple VT HEVC Hardware Encoder. These use the M-series hardware encoder and are far more efficient than software encoders.
• Rate Control: CRF (constant rate factor) — set CRF to 18–22 for high quality. Lower = better quality, larger file.

Step 7: Set Video Canvas and Output Resolution

Go to Settings → Video:

• Base (Canvas) Resolution: 1920×1080
• Output (Scaled) Resolution: 1920×1080 (match canvas unless you want to downscale)
• Common FPS Values: 30 (or 60 for high-motion)

Step 8: Test Record and Check the File

Click Start Recording, speak for 10–15 seconds, click Stop Recording, then navigate to your recording folder and open the file in QuickTime Player. Confirm the video and audio are both present and in sync. On some Mac setups there is a slight audio–video offset; if you notice it, use OBS's Audio Advanced Settings to add a negative sync offset on your mic source.

Adding a Teleprompter to Your OBS Recording Setup

One workflow that works exceptionally well on Mac: run Telepront's voice-scroll teleprompter in a separate window, positioned just below or alongside your camera. Because Telepront advances as you speak — hands-free — you can read your script while looking toward the lens without touching the keyboard, keeping your OBS recording uninterrupted from start to finish.

Common Mac-Specific OBS Issues

• Black camera preview: Check System Settings → Privacy → Camera → enable OBS.
• No audio in recording: Check System Settings → Privacy → Microphone → enable OBS. Also verify the correct input device is selected in the Audio Input Capture source.
• High CPU usage: Switch to Apple VT Hardware Encoder (Step 6). Software encoding on Mac burns far more CPU than necessary.
• Recording stops after a few seconds: Usually a disk space issue. Check your recording drive has enough free space (at least 20 GB free for longer recordings).
