Yuan SC400N2 M2 AIO M.2 HDMI and SDI Video Capture Card with 2-Channel Capture at 1080p60

A lecture recording system, a streaming encoder or a medical cart often has to record a camera and a screen at the same time, and a compact host may have only an M.2 slot to offer. The SC400N2 M2 AIO is Yuan’s 2-channel M.2 HDMI and SDI video capture card for that job, with one 3G-SDI and one HDMI input on a 22 x 80 mm module.

Yuan lists the card as two channels, so the SDI and HDMI sources are captured together, each at up to 1920 x 1080p at 60/50 fps. It also accepts 1080i, 720p and SD signals. 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 SC400N1 M2 AIO is the single-channel card with SDI loop-through, and the SC400N2 M2 SDI captures two SDI feeds with loop-through outputs in the same size.

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.
