Magewell Pro Capture Dual HDMI 4K Plus LT
Two simultaneous 4K HDMI channels on one PCIe card — dual-channel 4K ingest with genlock for professional broadcast workstations.
- Two simultaneous 4K HDMI inputs — capture two independent 4K UHD sources at up to 60fps simultaneously from a single PCIe card
- HDMI 2.0 on both channels — full 4K60 bandwidth on each input, supporting the highest-quality 4K cameras and production sources
- Genlock input — synchronise dual 4K capture to external facility reference for broadcast-standard frame timing across both channels
- Single PCIe slot for dual 4K channels — the most efficient route to two simultaneous 4K HDMI capture streams in a production workstation
- Low-latency PCIe DMA on both channels — direct to system memory with consistent 4K frame timing for production-grade editorial workflows
- Magewell SDK for frame-synchronised dual 4K access — precision timing across both channels for multi-camera 4K broadcast applications
Dual 4K HDMI — One PCIe Slot
The Magewell Pro Capture Dual HDMI 4K Plus LT delivers two independent 4K HDMI capture channels from a single PCIe card — the highest-specification dual-channel HDMI capture solution in the Pro Capture range. Both channels operate simultaneously and independently, each capturing at up to 3840×2160 at 60fps from HDMI 2.0 sources.
For production workstations that must simultaneously capture two 4K camera feeds — a wide shot and a close-up, two independent programme outputs, a camera and a graphics source — the Dual HDMI 4K Plus LT provides the complete solution from one PCIe slot. Two separate single-channel 4K cards would require two PCIe slots and provide no frame synchronisation between channels; the Dual HDMI 4K Plus LT solves both issues.
The Magewell SDK provides frame-synchronised access to both 4K channels simultaneously — essential for multi-camera productions where the timing relationship between two 4K sources must be preserved precisely.
Genlock at 4K Across Both Channels
The genlock input synchronises both capture channels to an external facility reference simultaneously. In a broadcast facility where all equipment must run on the same timing reference, genlock ensures the dual 4K capture is phase-locked to house sync — a requirement for broadcast-standard multi-camera production at 4K.
The "LT" designation identifies this as a specific technical variant within the Pro Capture Dual HDMI 4K Plus family. The core specification — dual 4K HDMI capture with genlock and PCIe DMA — is consistent with the family standard. Contact us with your specific system requirements and we will confirm suitability for your deployment.

The Pro Capture Dual HDMI 4K Plus LT serves the most demanding dual-camera 4K broadcast and production workstation applications requiring two simultaneous 4K HDMI channels with genlock.
Dual-Camera 4K Post-Production Ingest
High-end drama, documentary and commercial post-production houses capturing from two simultaneous 4K HDMI cameras or recorders can ingest both feeds directly into Adobe Premiere Pro, DaVinci Resolve or Avid from a single PCIe card with frame-synchronised timing.
4K Broadcast Multi-Camera Workstations
Television broadcast facilities running dual 4K HDMI ingest workstations within existing broadcast infrastructure use the genlock input to synchronise both channels to the facility reference — ensuring 4K frame timing is consistent with the rest of the broadcast signal chain.
Sports 4K Primary and Secondary Capture
Sports productions capturing a primary 4K match camera and a secondary 4K highlights or graphics feed simultaneously can ingest both on one workstation from a single card — with frame-synchronised access via the SDK for precise timing in replay and editing workflows.
Dual-View 4K Scientific Workstations
Research workstations requiring simultaneous 4K capture from two scientific imaging sources — a wide field microscope view and a high-magnification detail camera, for example — can capture both feeds frame-synchronised on a single dedicated workstation.
Dual-Camera 4K Medical Production
Medical education and surgical broadcast workstations capturing from two simultaneous 4K cameras — wide surgical field and close-up instrument view — can record both simultaneously with frame-accurate timing for clinical documentation and remote observation.
Dual 4K Programme Monitoring & QC
Quality control workstations monitoring two simultaneous 4K programme outputs — for compliance logging, technical quality assessment or A/B comparison of two 4K feeds — can receive and process both streams from a single PCIe card.
Dual-Source 4K Lecture Capture
University media production facilities building 4K lecture capture workstations requiring simultaneous capture from a 4K presenter camera and a 4K document or screen camera can ingest both at full 4K resolution from one card.
Enterprise Dual-Stream 4K Production
Large enterprise organisations producing broadcast-standard 4K content with two simultaneous camera sources — for investor days, major shareholder events and global internal communications — can run professional dual 4K ingest on a single production workstation.
Dual-Channel 4K Development & Testing
Broadcast technology developers and QA engineers building and testing dual 4K ingest systems, validating 4K signal integrity across two channels simultaneously, or developing multi-camera 4K production software can use the Magewell SDK for frame-synchronised dual 4K access.
