It is possible to use a GoPro HERO4 Black and HERO4 Silver as a webcam or for real-time capture to a computer. But it’s not quite as simple as just plugging your camera in with a USB cable (like you can with the newer HERO13 through HERO8).
For these classic models, you will need a few extra accessories to bridge the gap between the camera’s HDMI port and your computer’s USB port.
Note: This method works with the HERO4 Black and HERO4 Silver.
It does not work with the HERO4 Session, as that camera lacks an HDMI-out port.
Whether you want to use your GoPro for high-quality Zoom calls, streaming on Twitch, or recording tutorials directly to your hard drive, this guide will breathe new life into your older gear.
The Gear You Need
To make this work, you need to take the video signal coming out of the GoPro and convert it into a signal your computer thinks is a webcam.
- HDMI-to-USB Video Converter (Capture Card)
- Micro-HDMI to HDMI Cable
1. The Video Capture Device
Your computer’s HDMI port is almost certainly an output (for sending video to a monitor), not an input. To get video into your computer, you need a capture device (often called a “cam link” or “capture card”).
Top Recommendation: Elgato Cam Link 4K
This is the industry standard. It’s reliable, plug-and-play, and produces excellent image quality. It looks like a thumb drive and plugs directly into your USB port.
Budget Option: MavisLink / Generic Dongles
If the Elgato is out of budget, there are many generic “HDMI Video Capture” dongles available for under $20. While the picture quality is harsher (more contrasty and compressed) than the Elgato, they will get the job done for basic Zoom calls.

2. The Cable (Micro-HDMI)
The HERO4 Black and Silver use a Micro-HDMI port (the smaller port next to the Mini-USB port). You need a cable that goes from Micro-HDMI (camera end) to standard HDMI (capture card end).
Step-by-Step Setup Guide
Step 1: Get a “Clean” HDMI Signal
By default, the HERO4 outputs everything you see on the screen — including the battery icon, recording time, and settings overlays — over the HDMI signal. You don’t want your boss seeing your battery level during a meeting.
To turn this off:
- Press the Mode button until you see Setup.
- Select OSD (On-Screen Display).
- Set it to OFF.
Step 2: Connect the Hardware
- Plug the Micro-HDMI cable into the camera.
- Plug the other end into your Capture Device.
- Plug the Capture Device into your computer’s USB port.
- Turn on the GoPro.
Step 3: Select the Camera in Your Software
Your computer will recognize the capture device as a webcam (e.g., “Cam Link 4K” or “USB Video”). Select that as your video source in your software of choice:
- Zoom: Settings > Video > Camera > Select your capture device.
- Microsoft Teams: Settings > Devices > Camera.
- OBS Studio: Add a “Video Capture Device” source.
Critical Tips for Success
- Powering the Camera. The HDMI port does not provide power to the camera. The internal battery will only last about 60–90 minutes. For long streams, you should run the camera on external power using a Mini-USB cable connected to a USB wall charger. (Note: Remove the internal battery to prevent the camera from getting too hot while powered externally.)
- Audio. While the HDMI signal does carry audio, the GoPro’s internal microphone is mediocre at best and captures a lot of room echo. I strongly recommend using a separate USB microphone or your headset for audio, while using the GoPro strictly for video.
- Field of View (FOV). The default “Wide” view is often too wide for a webcam — it makes you look tiny and shows your entire messy room. Go into the GoPro settings (Video Settings) and change the FOV to Medium or Narrow (or “Linear” if available on your specific firmware) to get a more flattering, natural perspective.
- Lighting. The HERO4 struggles in low light. If your video looks grainy, don’t blame the HDMI connection — blame the lighting. Position a lamp in front of you (behind the camera) to light up your face or even use a ring light or soft-glow videoconferencing light. But even a cheap desk lamp makes a massive difference in quality.
