Magewell Pro Capture HDMI 4K
Single-channel 4K HDMI PCIe capture card — professional 4K ingest with genlock for broadcast workstations and 4K production servers.
- 4K HDMI 2.0 input — captures up to 3840×2160 at 60fps inside a production workstation or server via PCIe with broadcast-grade quality
- Genlock input — synchronises 4K capture to an external reference signal for broadcast-standard timing in multi-camera and facility integration workflows
- PCIe direct capture — low-latency 4K delivery to host memory via DMA, without USB bandwidth constraints or external device overhead
- Adobe Premiere Pro integration — Magewell's free plugin enables direct 4K capture into the Premiere editing timeline for professional post-production workflows
- Compatible with DaVinci Resolve, Avid, vMix and all major professional 4K video applications on Windows and Linux
- Driverless on Linux via V4L2 — suitable for 4K Linux ingest servers, automated 4K pipelines and broadcast infrastructure without driver dependencies
4K Capture Inside the Workstation
The Magewell Pro Capture HDMI 4K is a PCIe capture card that brings 4K HDMI capture permanently inside a production workstation or server. Where the USB Capture HDMI 4K Plus provides 4K capture externally via USB, the Pro Capture HDMI 4K is part of the workstation's hardware — always present, always available, with no external device to connect or manage.
The PCIe DMA architecture delivers 4K video data directly to system memory with lower latency and more consistent frame timing than USB-based 4K capture. In a dedicated 4K ingest workstation processing large volumes of high-resolution footage over extended sessions, this consistency matters for both reliability and system resource efficiency.
The Adobe Premiere Pro plugin from Magewell enables direct capture from the Pro Capture HDMI 4K into the Premiere timeline — no intermediate recording, no import step. The 4K signal from the camera becomes immediately available as timeline footage in the editing application.
Genlock — Broadcast Timing at 4K
The genlock input synchronises the Pro Capture HDMI 4K to an external reference signal. In a multi-camera 4K facility or a broadcast environment where the capture card must operate in phase with other equipment, genlock is a fundamental requirement — not a premium feature.
Without genlock, a capture card runs on its own internal clock, which may drift relative to other equipment in the facility. This causes frame timing inconsistencies that are imperceptible in isolation but create problems in multi-camera editing, broadcast distribution and downstream processing. Genlock eliminates these issues by locking the capture timing to the facility reference.
For single-channel 4K HDMI capture without genlock at lower cost, see the USB Capture HDMI 4K Plus (£385). For multi-format 4K capture with AIO inputs, see the Pro Capture AIO 4K Plus (£637). For dual-channel 4K, see the Pro Capture Dual HDMI 4K Plus LT (£1,207).

The Pro Capture HDMI 4K is designed for dedicated 4K production workstations and broadcast servers requiring permanently integrated 4K HDMI capture with genlock synchronisation.
4K Post-Production Ingest Workstations
Dedicated 4K ingest workstations for Adobe Premiere Pro, DaVinci Resolve and Avid can capture directly from 4K HDMI cameras and recorders into the editing timeline via the Magewell Premiere plugin — no intermediate file step, direct 4K ingest at full quality.
4K Broadcast Facility Integration
Broadcast facilities integrating 4K HDMI sources into existing infrastructure benefit from genlock — the Pro Capture HDMI 4K locks to the facility reference signal, ensuring frame timing consistency with other broadcast equipment in the signal chain.
4K Medical Imaging Workstations
Dedicated medical imaging workstations permanently connected to 4K HDMI surgical cameras, endoscopes and imaging equipment can capture at full 4K resolution via the integrated PCIe card for clinical documentation, specialist review and training content.
4K Scientific Research Workstations
Research workstations permanently connected to 4K microscopes, high-resolution spectrometers and precision imaging instruments capture 4K data directly into analysis software via the PCIe card — eliminating the external USB device from a precision scientific environment.
4K University Media Production Suites
Higher education media production facilities building dedicated 4K workstations for student film, television journalism and documentary programmes can integrate the Pro Capture HDMI 4K for consistent, hardware-integrated 4K acquisition.
Enterprise 4K Production Servers
Enterprise AV operations building 4K content production infrastructure on server hardware can deploy Pro Capture HDMI 4K cards in production servers for scheduled 4K ingest, live 4K capture and archive recording at maximum quality.
4K Broadcast Monitoring & QC Workstations
Quality control workstations receiving 4K HDMI programme feeds for loudness measurement, video analysis and compliance monitoring can use the PCIe-integrated card for consistent, low-latency 4K signal delivery to monitoring software.
4K Cinema & Drama Production Ingest
Film and high-end TV drama productions using 4K HDMI cameras can capture editorial reference feeds and production dailies into dedicated ingest workstations via the Pro Capture HDMI 4K for same-day editorial workflows.
4K Linux Ingest Server Development
Broadcast software developers and infrastructure engineers building 4K ingest servers on Linux can use the Pro Capture HDMI 4K as a driverless V4L2 device for 4K capture in automated pipelines without vendor driver maintenance.
