MG-11050 - Magewell Pro Capture SDI
Features
The Magewell Pro Capture SDI is a high-performance video capture card designed for professionals who require reliable and high-quality SDI signal acquisition. This PCIe Gen2 x1 card captures a single channel of SD/HD/3G-SDI input and offers a loop-through output, making it suitable for various applications, including live streaming, broadcasting, and video conferencing.

Comprehensive Input and Output Capabilities
Equipped with a BNC connector, the Pro Capture SDI supports SDI video inputs up to 2048×1080 pixels. It also features a loop-through interface, allowing the original SDI signal to be passed through to other devices without degradation. This functionality is particularly useful in workflows that require simultaneous monitoring and recording.
Advanced Video Processing Features
The card boasts a robust video engine capable of 10-bit video processing. It supports deinterlacing, cropping, color adjustment, hardware timestamping, color space conversion, up/down conversion, aspect ratio conversion, and on-screen display (OSD) functionalities. These features ensure that users can achieve optimal video quality tailored to their specific needs.
Broad Compatibility and Software Support
The Pro Capture SDI is compatible with multiple operating systems, including Windows, Linux, and macOS. It supports various APIs such as DirectShow, DirectKS, V4L2, and ALSA, ensuring seamless integration with a wide range of software applications. Notable compatible software includes VLC, OBS, XSplit, vMix, and Wirecast, among others.
Additional Features and Specifications
The card includes an integrated cable equalizer, extending cable lengths up to 330m for SD-SDI signals, 190m for HD-SDI signals, and 150m for 3G-SDI signals. It supports various SDI standards, including SD/HD/3Ga/3Gb/3Gb-DL/3Gb-DS, and offers support for 10/12-bit color depth and multiple color sampling formats. Additionally, the Pro Capture SDI provides support for up to 8 audio channels at 48KHz and features a low-latency mode, making it a versatile choice for professional video capture needs.
