Yuan SC710N1 M2 HDMI2.0 with Loop M.2 HDMI Video Capture Card with HDMI 2.0 Input at 4K60

When a compact computer records a presentation, a camera or an operator screen, someone usually still needs to see that source on a local display. The SC710N1 M2 HDMI2.0 with Loop is Yuan’s M.2 HDMI video capture card for that case, taking one HDMI 2.0 input at up to 4096 x 2160 at 60/50 fps and passing it on through an HDMI 2.0 output.

HDMI 2.0 modes run from 4096 x 2160 and 3840 x 2160 at 60/50/30/25/24 fps through 2560 x 1440p at 144 fps and 1920 x 1080p at up to 240 fps, down to SD and PC modes such as 720 x 576i and 640 x 480, with more modes available through the SDK. HDR10 and HLG are supported, as is HDMI 1.4b 3D. Formats are RGB24 and RGB32 at 4:4:4 8-bit, YUY2 at 4:2:2 8-bit, YV12 and NV12 at 4:2:0 8-bit, and P010 at 4:2:0 10-bit. Audio arrives as one embedded HDMI stereo stream, 16-bit at 32 to 48 kHz.

The capture card itself is an M.2 Type M card of 22 x 80 mm on a PCIe x4 link, cabled to an 85 x 23 mm board that carries the HDMI input and output. On-board processing covers cropping and scaling, automatic signal detection and deinterlacing. There is no built-in hardware encoder, so compression runs on the host or a GPU. Yuan’s Windows and Linux SDK supports multiple instances and multiple cards, and DirectShow and V4L2 support opens it to vMix, OBS, Zoom and Teams as well as custom software. The SC710N1 M2 HDMI2.0 is the same capture card without the output, and the SC710N1-L HDMI2.0 offers HDMI loop-through on a low profile PCIe card.

Yuan lists 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. The separate connector board lets the HDMI ports sit on the enclosure wall where they are needed, which we plan for as part of the system build.
