Product Description

The Magewell Pro Capture Mini SDI is a single-channel HD SDI video capture card in the Mini PCIe form factor, measuring just 30mm x 51mm, making it ideal for space-constrained embedded hosts and industrial computers. The card features MMCX input and loop-through connectors, supports SD/HD/3G-SDI signals, and includes an integrated cable equalizer that extends SD-SDI cable reach to 330 m, HD-SDI to 190 m, and 3G-SDI to 150 m. Maximum input resolution is 2048x1080; capture resolution reaches 2048x2160, with a maximum capture frame rate of 144fps. The full 10-bit video processing engine provides hardware de-interlacing, cropping, scaling, aspect-ratio conversion, color-space conversion, frame-rate conversion and OSD overlay. Hardware timestamping, SG-DMA transfer and ultra-low latency (64 video lines) make it well suited to broadcast recording, live production, medical imaging and industrial video applications.

Key Features

Ultra-compact Mini PCIe form factor (30mm x 51mm) designed for embedded hosts, industrial computers and space-constrained deployments
Supports SD/HD/3G-SDI signals including SD/HD/3Ga/3Gb/3Gb-DL/3Gb-DS standards and 2K (2048x1080) mode
Integrated cable equalizer extends SD-SDI reach to 330m, HD-SDI to 190m, and 3G-SDI to 150m — no external repeater required
MMCX loop-through interface simultaneously outputs the original signal without affecting the capture stream
SDI embedded audio support for up to 8 mono channels at 48KHz, with extraction of audio format information and channel status data
Full 10-bit video processing engine with hardware de-interlacing, cropping, scaling, aspect-ratio conversion, color-space conversion, frame-rate conversion and OSD overlay (PNG layer up to 2048x2160; RGBA OSD images loadable dynamically via SDK)
Unlimited capture streams from a single input channel, each with independent cropping, aspect ratio, color format, resolution, frame rate, de-interlacing and color adjustment settings
Ultra-low-latency mode (64 video lines) with hardware 100ns high-resolution timestamping for precise A/V synchronization, synchronizable across cards via SDK
SG-DMA video transfer with auto detection of Intel tiled GPU surfaces, AMD DirectGMA and Nvidia GPUDirect
Online firmware upgrade without system shutdown (in most cases no reboot required), with safe-upgrade auto-recovery if interrupted (firmware v1.21 and above); status LED indicates per-channel signal lock state
Selectable high-performance and low-power-consumption firmware modes, with minimum power draw of ~3.19W for thermally constrained environments
Bundled Magewell Capture SDK for cross-platform Windows/Linux/macOS integration; compatible with OBS, vMix, Wirecast, XSplit, VLC and other leading live production and recording software

Q&A

What kind of host system is this card designed for?

The Pro Capture Mini SDI uses the Mini PCIe interface and measures just 30mm x 51mm, making it suited to embedded industrial computers, compact media servers and other space-constrained hosts. It is not compatible with the standard PCIe slots found in typical desktop PCs.

How long an SDI cable can it support?

The integrated cable equalizer supports cable runs of up to 330m for SD-SDI, 190m for HD-SDI, and 150m for 3G-SDI — with no external repeater required along the cable.

What are the maximum supported resolution and frame rate?

The card accepts input up to 2048x1080 and captures at resolutions up to 2048x2160 and frame rates up to 144fps. Actual frame rate is limited by PCIe bandwidth and the on-board pixel clock; at 1920x1080 the practical maximum is approximately 80fps.

Can multiple cards be installed in a single system?

Yes. The system supports multiple cards running simultaneously, each controlled independently. Hardware timestamps can be synchronized across cards via the SDK, making the configuration suitable for multi-channel SDI capture.

How does this card compare to other models in the Pro Capture SDI range?

The Pro Capture Mini SDI uses a compact Mini PCIe form factor and supports a single 3G-SDI channel at up to 2K resolution, making it the right choice for embedded or space-constrained deployments. For standard PCIe card form factors, higher resolutions (such as 12G-SDI or 4K), or additional channels, refer to other models in the Pro Capture series.
