Magewell USB Capture HDMI 4K Plus
4K60 HDMI 2.0 to USB 3.0 with genlock — professional 4K capture for broadcast, medical imaging and high-end production.
- HDMI 2.0 input — captures true 4K (3840×2160) at up to 60fps via USB 3.0, delivering the full resolution of 4K cameras, medical imagers and production sources
- Genlock input — synchronise the capture to an external reference signal for frame-accurate multi-camera production and broadcast-standard timing
- Driverless UVC — works on Windows, macOS, Linux and ChromeOS immediately without driver installation, even at 4K resolution
- Bus powered from USB — 4K capture without an external power adapter, suitable for portable 4K field workflows and mobile production
- Compatible with Zoom, Teams, OBS Studio, vMix, Adobe Premiere, DaVinci Resolve and all major 4K-capable software applications
- Genlock enables frame-synchronised capture for multi-camera productions requiring consistent timing across all camera feeds
True 4K Capture via USB
4K resolution has become the standard for professional image acquisition. Mirrorless cameras, cinema cameras, PTZ cameras, 4K medical endoscopes and broadcast cameras all output 4K HDMI — and the USB Capture HDMI 4K Plus captures this at full resolution via a single USB cable.
Unlike 4K-labelled consumer capture cards that downscale or compromise on frame rate, the USB Capture HDMI 4K Plus captures the full 4K signal at up to 60fps, maintaining the quality that 4K cameras were chosen to deliver. This matters for content that is graded, archived or broadcast at full 4K quality.
Genlock — Professional Timing
The genlock input is the feature that separates the USB Capture HDMI 4K Plus from consumer 4K capture solutions. Genlock synchronises the capture device to an external video reference signal (house sync or tri-level sync), ensuring the captured frame timing matches other cameras and systems in the production.
Without genlock, individual capture devices may drift slightly out of phase with each other, causing timing inconsistencies in multi-camera productions and audio sync issues in broadcast environments. Genlock eliminates these issues entirely.
