Yuan SC400N2 M2 SDI M.2 SDI Capture Card with 2 x 3G-SDI Inputs at 1080p60

Two SDI cameras on a vehicle, an outside broadcast rig or an inspection system usually feed monitors as well as a recorder, and space for the recording computer is tight. The SC400N2 M2 SDI is Yuan’s 2-channel M.2 SDI capture card for that setup, with two 3G-SDI inputs and two loop-through outputs on a 22 x 80 mm module.

Both channels capture at up to 1920 x 1080p at 60/50 fps, and the card also accepts 1080p30, 1080i, 720p and SD-SDI. Each SDI output loops its incoming feed through, so the monitors stay in the chain. Audio arrives as two stereo embedded channels. Capture and preview formats are RGB24 and RGB32 at 4:4:4, YUY2 at 4:2:2, and YV12 and NV12 at 4:2:0, all 8-bit, so host software can take frames in the format it already uses.

The M.2 2280 module uses a B+M key and runs PCIe x2. On-board processing covers cropping and scaling, automatic signal detection and deinterlacing, and the card captures VANC data alongside video and audio. There is no hardware encoder, so any compression runs in software on the host. Yuan supplies a Windows and Linux SDK for custom applications, and the card works with DirectShow and V4L2 software; Yuan’s compatibility list names vMix, OBS, Zoom, Skype, Teams, Discord, Slack, Cisco Webex and GoToMeeting. The SC400N4 M2 SDI captures four SDI feeds on an M key module, and the SC400N2-L SDI puts two SDI inputs with loop-through on a low profile PCIe card.

Yuan lists driver support for Windows 7, 8, 8.1 and 10, Linux 2.6.14 or higher in 32-bit and 64-bit builds, Linux ARM, and NVIDIA Jetson TX2, Nano, AGX Xavier and Xavier NX modules. Yuan lists multi-instance and multi-device support for systems that run more than one capture session or card. The card measures 22 x 80 mm, the standard 2280 length, so it fits a 2280 M.2 slot on the host board.
