How to Capture HDMI Video to PC
Connect any HDMI camera, gaming console, production switcher or HDMI device to your PC for recording, live streaming or video conferencing — step by step.
In this guide
What You Need
To capture HDMI video on a PC, you need three things: an HDMI source device (camera, console, laptop, switcher), an HDMI capture card, and capture software. The capture card is the hardware bridge between the HDMI signal and your computer.
- HDMI source — a camera, gaming console, DSLR/mirrorless, laptop, production switcher or any device with HDMI out
- HDMI capture card — USB (connects externally) or PCIe (installs inside desktop)
- HDMI cable — standard HDMI or Mini/Micro HDMI with adapter depending on your camera
- Capture software — OBS Studio (free), vMix, Adobe Premiere Pro, DaVinci Resolve or any application accepting a camera/video source
- USB 3.0 port — essential for USB capture devices; USB 2.0 does not have enough bandwidth
⚠️ Important: Some sources output HDCP (copy-protection) which capture cards cannot record by design. Cameras, computers, production switchers and most gaming consoles (in game mode) do not use HDCP. Blu-ray players, streaming sticks and TV set-top boxes do. If your source has HDCP, you will see a black screen.
USB vs PCIe Capture Cards
There are two types of capture card. Choosing the right type for your situation matters before purchasing.
USB Capture Devices
USB capture devices connect to any computer via USB — laptops, desktops, MacBooks, Linux machines. They are portable, typically driverless (plug and play via UVC standard), and simple to set up. Most USB capture devices work immediately when plugged in without any software installation.
Best for: Content creators, streamers, YouTubers, influencers, educators, journalists, video conferencing, location work and anyone using a laptop.
Limitation: USB bandwidth is shared with other USB devices. Always connect directly to a USB 3.0 port on the motherboard — not a USB hub.
PCIe Capture Cards
PCIe capture cards install inside a desktop PC or server via the PCIe slot on the motherboard. They provide lower latency than USB, more stable frame timing, and are better suited for 24/7 ingest servers, broadcast workstations and multi-channel capture. Not available for laptops.
Best for: Broadcast facilities, corporate production workstations, Linux ingest servers, post-production houses, medical imaging, university media suites and any permanent desktop-based workflow.
M.2 Capture Cards
A third option — Magewell's Eco Capture range uses the M.2 PCIe slot found in most modern laptops and compact PCs. This brings capture-card capability to systems without a full-size PCIe slot, including some NUC-style small form factor PCs.
Step-by-Step Setup (USB Capture Device)
This guide covers USB capture — the most common setup. PCIe cards follow the same software steps after installation in your PC's PCIe slot.
-
1
Check your HDMI source output
Confirm your camera or device outputs a clean HDMI signal. On most cameras, enable Clean HDMI output in the menu — this disables on-screen overlays and sends a clean image. Check your camera manual for the specific option name (Canon calls it "HDMI output"; Sony uses "HDMI Info. Display Off").
-
2
Connect to a USB 3.0 port directly
Plug the capture card into a USB 3.0 port (look for the blue tab inside or an "SS" label). Connect directly to the PC — not through a USB hub or dock. USB hubs share bandwidth and cause frame drops, dropped signals or black screens. If using a laptop with only USB-C ports, use a USB-C to USB-A adapter that supports USB 3.0, not USB 2.0.
-
3
Connect HDMI from source to capture card
Run an HDMI cable from the HDMI output of your camera or device into the HDMI Input on the capture card. If your camera has a Mini HDMI or Micro HDMI output, use the correct adapter or cable. UVC capture cards (Magewell USB Capture, Elgato) require no driver installation — Windows and Mac recognise them as cameras automatically.
-
4
Open OBS Studio and add the capture source
Open OBS Studio. In the Sources panel, click + and select Video Capture Device. Give it a name and click OK. In the Properties window, click the Device dropdown and select your capture card from the list. It will typically appear with the card's brand name or model.
-
5
Configure resolution and frame rate
In the Video Capture Device properties, set Resolution to match your camera's output (e.g. 1920×1080). Set Frame Rate to match — 25fps for PAL cameras, 30fps for NTSC, or 50/60fps for high-frame-rate sources. Mismatched settings cause a black screen or degraded quality. For 4K capture, set 3840×2160.
-
6
Add audio from the capture card
In OBS, go to Settings → Audio and check that your capture card is listed as an audio input, or add an Audio Input Capture source and select the capture card. HDMI carries audio embedded in the signal — the capture card receives it automatically. If the audio is delayed relative to video, see the Audio Sync section in troubleshooting below.
-
7
Test before going live
Click Start Recording (not streaming) to test. Record 30 seconds, stop, and review the footage. Check for image quality, correct resolution, audio sync and stable frame rate. Only stream or go live after confirming the capture is clean. Once confirmed, configure your stream key or recording settings and go.
Software That Works With Capture Cards
HDMI capture cards that use the UVC (USB Video Class) standard work with virtually any software that accepts a camera input. PCIe cards may need the Magewell plugin in some applications.
Free software
- OBS Studio — the most widely used free tool for streaming and recording. Works with all UVC capture cards out of the box. Add as Video Capture Device.
- Zoom / Microsoft Teams / Google Meet — select the capture card as the camera in video settings. Any UVC device appears as a webcam.
- VLC Media Player — can preview and record from capture cards via Media → Open Capture Device.
Professional software
- vMix — popular live production software with native support for Magewell cards, Elgato and Blackmagic via DirectShow or SDK. Add as Camera input.
- Adobe Premiere Pro — supports Magewell Pro Capture PCIe cards via the free Magewell plugin for direct timeline capture. UVC USB cards work via Media → Capture.
- DaVinci Resolve — works with Blackmagic capture devices natively, and Magewell cards via UVC or the Resolve capture interface.
- Wirecast — supports Magewell, Blackmagic and Elgato cards. Add as Local Camera source.
- XSplit Broadcaster — works with all UVC USB capture devices as webcam sources.
Video conferencing
For Zoom, Teams, Google Meet and Webex — any UVC USB capture device appears as a webcam in the application's video settings. Select the capture card as the camera source. This allows professional DSLR or mirrorless cameras to be used in place of a webcam, giving significantly better video quality in meetings and webinars.

Troubleshooting Common Issues
🖥️ Black screen — capture card connected but no image
Most likely cause: HDCP copy protection. HDCP blocks capture by design. Check your source is not a streaming stick, Blu-ray player or set-top box.
Other causes: Wrong USB port (try a different USB 3.0 port directly on the motherboard); wrong resolution set in OBS (match to source output); capture card not selected as video source in software; HDMI cable fault (try a different cable); camera not in clean output mode.
📉 Frame drops, stuttering or unstable image
Almost always caused by USB bandwidth. Disconnect all non-essential USB devices. Connect the capture card to a USB 3.0 port directly on the motherboard — not a USB hub. In Device Manager (Windows), check the capture card shares a USB controller with other devices — move it to a port on a different controller if so. Reduce resolution or frame rate as a test.
💚 Green tint or incorrect colours
Colour space mismatch between source and capture settings. In OBS Video Capture Device properties, try changing Video Format from MJPEG to YUY2, or check the Colour Space setting. If using Magewell cards with their driver software, set the output colour space to match OBS settings. Update to the latest Magewell driver version.
🔊 Audio out of sync with video
Audio processing and video processing have different latencies through a capture card. In OBS, right-click your audio source → Advanced Audio Properties → set a positive Sync Offset in milliseconds. Start at 250ms and adjust until aligned. Alternatively, use the Magewell USB Capture Utility to check audio sync settings on supported cards.
❌ Capture card not appearing in OBS device list
The capture card is not being detected as a UVC device. Try: unplug and reconnect to a different USB port; restart OBS after connecting the card; on Windows, open Device Manager and check for the card under Imaging Devices or Sound and Video; check Windows Device Manager for driver errors. On Mac, check System Information → USB to confirm the device is listed.
📷 Camera shows image in capture but very low quality / blurry
The capture resolution is set lower than the camera output. In OBS → Video Capture Device Properties, set Resolution to Custom and enter the exact resolution your camera outputs (e.g. 1920×1080). Also check the camera is in its highest quality HDMI output mode — many cameras default to lower quality HDMI output unless configured in the menu.
🔌 Capture card works but disconnects randomly
USB power management is putting the port to sleep. On Windows: Device Manager → Universal Serial Bus Controllers → right-click each hub → Properties → Power Management → uncheck "Allow the computer to turn off this device to save power". Also disable USB Selective Suspend in Windows Power Options. Some capture cards require more power than USB 2.0 delivers — confirm USB 3.0 connection.

Contact Technical SupportFrequently Asked Questions
Do I need to install drivers for a USB capture device?
Most modern USB capture devices use UVC (USB Video Class) — natively supported by Windows 10/11, macOS and Linux with no driver needed. Magewell USB Capture and Elgato Cam Link devices are UVC compliant and plug in as cameras automatically. Some older or lower-cost cards require proprietary drivers.
Why is my capture card showing a black screen?
The most common causes are: (1) HDCP copy protection on the source — streaming sticks, Blu-ray players and TV boxes output HDCP which cannot be captured; (2) using a USB 2.0 port instead of USB 3.0 — check for the blue tab or SS label; (3) resolution mismatch in OBS — set to match the camera output; (4) wrong device selected in software. Try each fix in order.
What is the difference between a USB and PCIe capture card?
USB cards connect externally and work with any computer including laptops — portable and plug-and-play. PCIe cards install inside a desktop PC motherboard slot — lower latency, more stable for 24/7 ingest servers and broadcast workstations, not available for laptops. Magewell USB Capture covers USB; Magewell Pro Capture and Blackmagic UltraStudio PCIe cover desktop workstations.
Can I capture 4K HDMI via USB?
Yes — with a USB 3.0 capture card rated for 4K. The Magewell USB Capture HDMI 4K Plus and 4K Pro support 4K USB capture. USB 3.0 provides 5Gbps bandwidth — sufficient for 4K at standard bitrates with efficient compression. USB 2.0 cannot handle 4K.
Can I use a capture card for video conferencing in Zoom or Teams?
Yes. UVC USB capture devices appear as standard webcams to any application. In Zoom, Teams, Google Meet or Webex, go to video settings and select the capture card as the camera. This lets you use a professional DSLR, mirrorless or broadcast camera in place of a webcam for significantly better video quality.
Does HDCP prevent capture?
Yes. HDCP copy-protection blocks capture by design. Sources using HDCP — Blu-ray, Netflix, Amazon Prime, Sky TV, most streaming devices — cannot be captured. Sources that do NOT use HDCP: cameras, computers, production switchers, gaming consoles (in game output mode), document cameras and most professional AV equipment.
What capture card do content creators and YouTubers use?
The most popular professional choices are the Magewell USB Capture HDMI Gen 2 (broadcast-grade, driverless) and Elgato Cam Link 4K (compact, ideal for cameras). The Elgato 4K60 Pro MK.2 is popular for desktop gaming capture. For multiple cameras, the Magewell USB Capture HDMI Plus with loop-through is frequently used in multi-camera setups.
Can I capture from two cameras simultaneously?
Yes — with either two USB capture devices (each on their own USB 3.0 port on separate controllers), a dual-channel USB card like the Magewell USB Fusion, or a dual-channel PCIe card like the Magewell Pro Capture Dual HDMI. Each appears as a separate camera device in OBS, allowing a multi-camera production from one machine.
