Yuan SC5A0N1 PCIe HDMI, SDI and DVI Frame Grabber with 1080p60 Input
PCI ExpressSC5A0N1 Overview
A recording or streaming PC that meets many kinds of source, from SDI cameras to older composite equipment, needs a wide choice of inputs and enough headroom to encode. The SC5A0N1 is Yuan’s PCIe HDMI, SDI and DVI frame grabber with six input types and a built-in H.26X hardware encoder, so compression happens on the card rather than on the host processor.
The card has one each of HDMI, SDI, DVI-I, YPbPr, S-Video and CVBS as a single capture channel. Sources arrive at up to 1920 x 1080p at 60/50 fps and the card delivers 1920 x 1080p at 30/25 fps to the host. Capture and preview formats are RGB24 and RGB32 at 4:4:4, YUY2 at 4:2:2 and YV12 or NV12 at 4:2:0, all 8-bit, so host software receives frames in the layout it already expects. Cropping, scaling, deinterlacing and automatic signal detection run on the card rather than in host code. SDI covers 3G-SDI, HD-SDI and SD-SDI formats, and CVBS and S-Video cover 480i and 576i. Audio is one stereo embedded input at 16-bit and 32 to 48 kHz.
It is a PCIe x1 Gen2 card with H.26X hardware encoding on board. For software, Yuan provides Windows and Linux SDKs and lists vMix, OBS, Zoom, Skype, Teams and Webex among compatible applications through DirectShow and V4L2. The SC550N1-L AIO captures at the full 1080p60 rate without an encoder, and the SC5A0N1 M2 HDV brings the same encoder to an M.2 card.
Yuan lists support for Windows 7, 8, 8.1 and 10, Linux kernel 2.6.14 or later in 32-bit and 64-bit builds, Linux on ARM, and NVIDIA Jetson TX2, Nano, AGX Xavier and Xavier NX. The board measures 107 x 101.3 mm, with S-Video, BNC, HDMI and DVI-I connectors on the bracket. It has 16 GPIO lines, and Yuan lists multi-device and multi-instance support.

Official Yuan UK Distributor
Things Embedded is an official Yuan UK distributor, supplying the SC5A0N1 for UK AV and industrial video projects. Within the Yuan range the SC550N1-L AIO captures at 1080p60 without an encoder, and the SC5A0N1 M2 HDV has the H.26X encoder on an M.2 card.
With six input types the SC5A0N1 sits among our PCIe capture cards, our HDMI capture cards and our SDI capture cards. Where one PC must record almost any source with hardware encoding, this is the model to specify.
