Magewell Pro Capture AIO 4K Plus

One Card, Three Signal Types: HDMI 4K, SDI 4K, and Analogue Input

The Magewell Pro Capture AIO 4K Plus is a single PCIe x4 card that accepts HDMI, SDI, and DVI/analogue inputs simultaneously, with each signal type processed by its own dedicated FPGA. AIO stands for all-in-one, and that is precisely what this card delivers: a single-slot solution for broadcast and production environments that work with multiple signal formats from the same server. At £740, it replaces what would otherwise require multiple separate capture cards with one integrated solution for mixed-signal 4K ingest.

What It Captures

The Pro Capture AIO 4K Plus supports three input types simultaneously:

• HDMI: up to 3840x2160 at 60fps (4K60)
• SDI: up to 3840x2160 at 30fps via 12G-SDI (4K30), with backward compatibility for 6G-SDI, 3G-SDI, HD-SDI, and SD-SDI
• DVI and analogue: for legacy and mixed-format sources that would otherwise require conversion upstream

Each input has its own independent FPGA processing pipeline. There is no shared processing bottleneck between signal types. Colour conversion, scaling, and deinterlacing happen independently on each pipeline, and each input presents as a separate capture device to the host operating system.

Who This Card Is For

The Pro Capture AIO 4K Plus is the right choice for broadcast and production teams in environments where signal format is not standardised across all sources:

• Broadcast studios receiving SDI feeds from camera and routing infrastructure alongside HDMI outputs from laptops, graphics computers, and presentation systems
• Live event AV teams running mixed-format capture rigs where source types vary by venue or production configuration
• Archive and digitisation facilities working with modern 4K SDI sources and legacy analogue or DVI equipment within the same workflow
• Mobile broadcast and flyaway production kits where PCIe slot count is limited and a single AIO card is more practical than three separate input cards

Why Independent FPGAs Matter for Mixed-Format Capture

Multi-input capture cards that share a single processing core across all inputs must time-slice across those inputs under load, which creates resource contention and can reduce effective throughput per channel. The Pro Capture AIO 4K Plus assigns a dedicated FPGA to each signal type. Running an HDMI 4K source, a 12G-SDI source, and an analogue source simultaneously does not cause any of them to compete for processing resources. Each pipeline operates at full capability regardless of what the others are doing.

The PCIe Slot Efficiency Argument

Fitting three separate capture cards (HDMI 4K, SDI 4K, analogue) into a server means three PCIe slots, three driver installations, and three separate hardware maintenance considerations. The Pro Capture AIO 4K Plus consolidates all three into a single PCIe x4 slot. In chassis where slot count is constrained, and in deployments where signal type flexibility is a recurring requirement, this is often the only practical way to achieve multi-format 4K capture from a single server.

Software Compatibility

Compatible with vMix, Wirecast, OBS Studio, Adobe Premiere Pro, and FFmpeg. Supported on Windows 10, Windows 11, and Windows Server; Linux kernel 3.x and above; and macOS 10.14 and later. Each input appears as an independent capture device to the host OS and production software.
