Magewell Pro Capture Dual SDI
Two simultaneous 3G-SDI inputs on one PCIe card — dual-channel broadcast SDI ingest for professional production workstations and servers.
- Two simultaneous independent 3G-SDI inputs — capture two SDI sources simultaneously at up to 1080p60 per channel from a single PCIe x1 card
- Full SD-SDI, HD-SDI and 3G-SDI support per channel — automatic format detection across the complete range of professional broadcast SDI formats
- Single PCIe slot for dual-channel broadcast SDI — one card replaces two single-channel SDI capture devices, conserving PCIe slots and simplifying infrastructure
- PCIe DMA low-latency capture on both channels — broadcast-grade signal delivery directly to system memory without external device overhead
- Both channels driverless on Linux via V4L2 — suitable for dual-feed Linux broadcast servers and automated SDI ingest pipelines
- Frame-synchronised dual-channel access via Magewell SDK — precision timing for multi-camera broadcast workflows requiring synchronised capture
Dual Broadcast SDI from One PCIe Slot
The Magewell Pro Capture Dual SDI places two independent 3G-SDI capture channels on a single PCIe x1 card. In broadcast environments where SDI is the signal standard of every camera, switcher and infrastructure component, having two SDI capture channels permanently inside a workstation or server is the fundamental requirement for multi-source ingest.
Both SDI channels are independently active and simultaneously available. Each captures at up to 1080p60 from any SD-SDI, HD-SDI or 3G-SDI source — a camera, a production switcher output, an ISO feed from a broadcast router, or a confidence output from a playout system. The Magewell SDK provides frame-synchronised access to both channels for applications requiring precise timing across two SDI sources.
Broadcast Infrastructure Integration
Where HDMI is the dominant consumer and prosumer format, SDI is the signal of the professional broadcast infrastructure — the format that cameras, routers, monitors, production switchers and recording devices use in studios, OB vehicles and broadcast facilities. The Pro Capture Dual SDI integrates naturally with this infrastructure.
Its driverless Linux V4L2 compatibility makes it the correct choice for Linux-based broadcast servers — automated ingest systems, playout servers and media processing infrastructure where vendor driver dependencies are undesirable in production environments.

The Pro Capture Dual SDI is designed for broadcast workstations and servers requiring two simultaneous SDI channels inside a production PC or rack server.
Broadcast Studio Dual-Camera Ingest
Production workstations in broadcast studios ingesting from two SDI camera sources simultaneously — programme camera and cutaway camera, or studio camera and remote location feed — use both SDI channels for independent, low-latency ingest to editing and broadcast software.
News Desk Primary and Backup Ingest
News production systems capturing the main anchor camera on channel one and a backup or B-roll camera on channel two simultaneously, with both feeds available to news management systems and editing workstations from a single card.
Multi-Cam Post-Production Ingest
Post-production facilities ingesting from two SDI cameras or tape sources simultaneously can accelerate multi-cam project ingest, capturing two ISO recordings in parallel from a dedicated ingest workstation with a single Dual SDI card.
Sports Production Analysis Workstations
Sports analysis workstations capturing two simultaneous SDI camera feeds — attack camera and defence camera, or two different match angles — for real-time tactical analysis and coaching review software.
Broadcast Archive & Compliance Recording
Compliance recording workstations required to capture two simultaneous broadcast feeds for regulatory archive — for example, two transmission channels from a broadcast facility output — can ingest both SDI outputs from a single Pro Capture Dual SDI card.
Theatre & Live Event Dual-Camera Server
Event production servers capturing two simultaneous SDI camera feeds from live performances — wide stage and close-up — for real-time streaming and post-event editing, all ingested from a single card inside the production PC.
Linux Dual-Feed Broadcast Servers
Linux-based broadcast ingest servers receiving two simultaneous SDI programme feeds can use both Dual SDI channels as driverless V4L2 devices — direct kernel access for FFmpeg, GStreamer or custom broadcast pipeline integration without proprietary drivers.
Dual-Camera Clinical Recording Workstations
Medical education and clinical recording workstations capturing from two SDI cameras simultaneously — surgical field and instrument camera — for procedure documentation, telemedicine and medical training content production.
Frame-Synchronised Dual-SDI Development
Broadcast software developers requiring frame-synchronised access to two simultaneous SDI sources can use the Magewell SDK's dual-channel synchronisation for applications where the precise timing relationship between two SDI feeds is critical.
