When the source is a 4K camera, laptop or media player and the room display has to stay at full quality, you need a capture device that does not force everything down to HD. The USB Capture HDMI 4K Plus is a 4K HDMI to USB capture device. It takes one HDMI signal, up to 4K at 60 frames per second, and passes it to a computer over USB so streaming, recording or conferencing software can use it as a video source. Its HDMI loop-through keeps the display fed, and a microphone input and headphone output are built in.
4K at 60 goes in. 4K at 30 is captured.
The HDMI input and the loop-through both handle up to 4096×2160 at 60 frames per second in full 4:4:4 colour. Capture to the computer at 4K is up to 30 frames per second. The 4K capture formats are 4096×2160 and 3840×2160 at 23.98, 24, 25, 29.97 and 30. So a 4K 60 source is shown at 60 on the loop-through monitor, and the computer receives 4K at up to 30. At 1920×1080 capture goes up to 60 frames per second, and 2560×1440 is captured at 60.
What goes in
- HDMI. One HDMI 2.0 input, which also accepts DVI-D. Custom EDID is supported, which lets you control what resolution the source is told to send. If your workflow depends on HDR, check with us before ordering.
- HDMI audio. Up to eight embedded channels on the input. Up to two channels are passed to the computer.
- Microphone. A 3.5 mm microphone socket carries two channels of audio into the capture, so a presenter or commentator can be recorded with the picture.
What comes out
- Loop-through. One HDMI output that passes the source on to a monitor or projector, up to 4096×2160 at 60 frames per second in 4:4:4. The room display keeps the source at up to 4K 60 while you capture.
- To the computer. Uncompressed video over USB in NV12, I420, YUY2, UYVY, RGB24 or RGB32 format.
- Headphones. A 3.5 mm headphone socket plays either the sound from the HDMI signal or sound from the computer.
Where it earns its place
The device can crop, scale up or down, de-interlace (turn an interlaced picture into full frames), change aspect ratio, convert colour format, convert frame rate, and flip or mirror the picture. This is FPGA-based processing with zero CPU usage. In plain terms, the conversion work is done inside the device, which frees your computer for the software you are running. Scaling makes the picture fit the size you ask for, using the detail in the source, so you can take a 4K source and hand your streaming software 1080p without changing anything at the source.
- Power. It runs from the USB port, with no additional power source required. The maximum draw is about 7 W (1.4 A at 5 V), more than the HDMI Plus (about 4.5 W), so plug it directly into the computer.
- Size. 98.1 × 56.8 × 17 mm, which slips into a laptop bag. A 63 cm USB 3.0 cable is in the box.
Setting it up
- Driver-free. The USB Capture family installs without a driver and detects the input automatically. Connect the source, plug the USB cable into the computer, then pick the device in your software.
- USB port. The connection is USB 3.0. It is compatible with USB 2.0 and USB 3.1 Gen 1 as well.
- Operating systems. Windows 10 and 11 (and Windows Server 2016 to 2025), Linux with kernel 2.6.35 and above on x86, x64 and ARM, Mac OS X 10.9 and above, macOS 10.12 and above, and Chrome OS.
- Software. It works with Zoom Rooms, Microsoft Teams, Skype for Business, Google Hangouts, GoToMeeting, VLC, OBS Studio, XSplit and QuickTime Player, plus other DirectShow, V4L2 or AVCaptureSession software.
- Settings and firmware. Magewell’s free USB Capture Utility shows and changes the capture settings and upgrades the firmware.
Where it sits in the range
The USB Capture HDMI Plus also accepts a 4K input but captures at up to 2048×2160, and draws less power. The USB Capture HDMI 4K Pro is the next 4K model up; ask us which one suits your source. The whole family is on the USB Capture range page.
