Yuan SC400N1 M2 HDV M.2 HDMI and DVI Capture Card with 1080p60 Input

Imaging equipment, test sets and older industrial PCs often output DVI or analog component video rather than HDMI, and the PC that records them may be a small embedded box with no PCIe slot to spare. The SC400N1 M2 HDV is Yuan’s M.2 HDMI and DVI capture card for that mix of sources, with HDMI, DVI-I and YPbPr inputs on one 22 x 60 mm module.

The card has a single capture channel and accepts up to 1920 x 1080p at 60/50 fps. Audio arrives as one stereo embedded channel, with analog left and right available through a wafer connector. 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. On-board processing covers cropping and scaling, automatic signal detection and deinterlacing. There is no hardware encoder, so any compression runs in software on the host.

The M.2 2260 module uses a B+M key and runs PCIe x1, so it fits boards whose M.2 slot is too short for a 2280 card. 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 MC HDV takes HDMI and component sources on a Mini PCIe card, and the SC540N1 M2 HDV is Yuan’s earlier 22 x 60 mm card, which captures at up to 1080p30.

Yuan lists driver support for Windows 7, 8, 8.1 and 10, Linux 4.8 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 60 mm, so it suits host boards that provide a 2260 M.2 slot.
