The Professional 4K HDMI Capture Standard

The Magewell Pro Capture HDMI 4K Plus represents the professional broadcast standard for single-channel 4K HDMI PCIe capture — combining HDMI 2.0 4K input with genlock synchronisation and the enhanced signal processing of the Plus range in a single PCIe card.

The "Plus" designation in the Pro Capture range reflects an enhanced feature set over the base Pro Capture HDMI 4K — the same 4K HDMI capture capability with additional broadcast-grade capabilities that professional production workstations and broadcast facility integration require. For the demanding requirements of high-end post-production, broadcast monitoring and 4K facility infrastructure, the HDMI 4K Plus is the appropriate specification.

Adobe Premiere Pro users can capture directly from the Pro Capture HDMI 4K Plus into the editing timeline using the free Magewell plugin — no intermediate recording step, no file import, direct 4K editorial ingest from camera to timeline.

Genlock and Broadcast Integration

The genlock input is what differentiates professional broadcast capture from prosumer capture at 4K. In a broadcast facility, every piece of equipment runs on the same reference timing — the house sync signal that ensures frame-accurate synchronisation across cameras, monitors, recorders and distribution equipment.

The Pro Capture HDMI 4K Plus locks its capture timing to this house sync via the genlock input, ensuring that the captured 4K frames are precisely aligned with the rest of the facility infrastructure. This is the correct specification for broadcast facilities, post-production houses and any environment where precise timing alignment matters.

For the HDMI 4K Plus LT variant with specific technical differences, see the Pro Capture HDMI 4K Plus LT (£604). For multi-format 4K capture with SDI and analogue inputs, see the Pro Capture AIO 4K Plus (£637).

The Pro Capture HDMI 4K Plus is the professional standard for single-channel 4K HDMI PCIe capture with broadcast-grade genlock in demanding production and broadcast environments.

🎬

High-End 4K Post-Production Ingest

High-end drama, documentary and commercial post-production houses running dedicated 4K ingest workstations on Adobe Premiere Pro, DaVinci Resolve or Avid specify the HDMI 4K Plus for its broadcast-grade capture quality, genlock synchronisation and production-house reliability standards.

📡

4K Broadcast Facility Workstations

Television broadcast facilities installing 4K HDMI ingest workstations within existing broadcast infrastructure require genlock to synchronise with the facility reference. The HDMI 4K Plus locks to house sync, ensuring 4K capture timing is consistent with the rest of the broadcast signal chain.

🏆

Premium Sports Production Workstations

Elite sports productions using 4K HDMI cameras for the highest-quality analysis and broadcast clips can specify the HDMI 4K Plus in dedicated sports analysis workstations — 4K ingest at broadcast quality with genlock for facility integration.

🎥

4K Cinema & Drama Production Dailies

Film and high-end television drama productions running 4K dailies ingest on location or in the post house can use the HDMI 4K Plus for production-quality 4K capture directly into the editorial system via the Adobe Premiere plugin.

🔬

High-Specification 4K Research Workstations

Research institutions and national laboratories with 4K imaging systems requiring the highest available PCIe capture specification for precision scientific recording can specify the HDMI 4K Plus for dedicated research workstations.

📊

4K Programme Quality Control

Broadcast QC workstations monitoring and logging 4K HDMI programme outputs for compliance, technical quality assessment and regulatory archive need the genlock synchronisation of the HDMI 4K Plus for frame-accurate capture aligned to the broadcast facility timing.

🏥

4K Surgical Broadcast Workstations

Medical centres running dedicated 4K surgical video workstations for live broadcast of surgical procedures to remote observation and medical education audiences need broadcast-grade 4K capture with the reliability and signal quality of the HDMI 4K Plus.

🏛️

Government & Parliamentary 4K Production

Government broadcast facilities, parliamentary proceedings production and official state broadcast infrastructure operating at 4K quality standards require broadcast-grade PCIe capture with genlock for integration with professional broadcast facility timing.

⚙️

What is the difference between the HDMI 4K and the HDMI 4K Plus?

The Pro Capture HDMI 4K (£432) provides 4K HDMI capture via PCIe. The Pro Capture HDMI 4K Plus (£595) is the enhanced Plus range specification — offering broadcast-grade signal processing, genlock synchronisation and the production-standard feature set designed for professional broadcast facility integration. If genlock and enhanced broadcast features are required, the Plus is the correct specification.

What is the difference between the HDMI 4K Plus and the HDMI 4K Plus LT?

The Pro Capture HDMI 4K Plus (£595) and HDMI 4K Plus LT (£604) are closely related variants with specific technical differences. For guidance on which is correct for your specific application, please contact us — our team can advise based on your system requirements and infrastructure.

Does it work with Adobe Premiere Pro?

Yes. Magewell provides a free plugin for Adobe Premiere Pro that enables direct capture from the Pro Capture HDMI 4K Plus into the editing timeline. Install the plugin, select the card as the capture device in Premiere's capture panel, and ingest 4K directly from your HDMI source without any intermediate recording step.

Is the genlock essential or optional?

The genlock is optional in standalone workstation use — the card captures accurately without an external reference. It becomes essential when integrating into a broadcast facility where all equipment must run on synchronised timing. Without genlock, a capture card runs on its own clock which may drift relative to other facility equipment, causing timing inconsistencies in multi-camera productions and broadcast distribution.
