Magewell Pro Capture SDI Overview

Input SDI video to your computer with this Pro Capture SDI from Magewell. The Pro Capture SDI is a low-profile PCIe 2.0 card that allows for capturing one channel of SD/HD/3G-SDI input via a BNC connector, while also offering an SDI loop output on a second connector. The card supports numerous SDI formats and color sampling modes, a 2K mode, 10- and 12-bit color depths, up to 8 audio channels at 48 kHz, and output resolutions up to 2048 x 2048 with frame rates up to 120 fps. Pro Capture SDI is also capable of numerous video processing features, including cropping, scaling, deinterlacing, aspect ratio conversion, color format conversion, video frame rate conversion, and video OSD composition.

The Pro Capture SDI supports multiple cards per system and unlimited output streams with independently adjustable parameters per stream. Additional features include ultra-low latency, timestamp and A/V synchronization, and LED status indicators. The card supports Windows, Linux, and macOS operating systems, multiple APIs for Windows and Linux, and provides Windows SDKs for easier integration.
