Yuan SC5A0N4 HDMI PCIe HDMI Video Capture Card with 4 x HDMI Inputs and 1080p30 Capture

A multi-camera recorder, a meeting room with several displays or a monitoring desk watching four HDMI sources needs every feed captured at once, without four cards in four slots. The SC5A0N4 HDMI is Yuan’s four-channel PCIe HDMI video capture card for that, with four HDMI inputs on one PCIe x4 board and an H.26X encoder that compresses them on the card.

Each HDMI input accepts 1920 x 1080p at 60/50 fps and captures at 30/25 fps, with 1080i, 720p and computer modes from 640 x 480 to 1280 x 1024 also listed. Frames come out as 8-bit RGB24, RGB32, YUY2, YV12 or NV12, from full 4:4:4 color down to 4:2:0 for lighter encoding and streaming loads. Each channel captures stereo embedded audio from HDMI at 16-bit and 32 to 48 kHz, so sound stays with each picture.

The card uses a PCIe x4 Gen2 slot and supports multiple instances and multiple cards per host, with cropping and scaling, automatic signal detection and deinterlacing on board and a watchdog. Development runs on Yuan’s Windows and Linux SDK, while DirectShow and V4L2 support lets off-the-shelf software including vMix, OBS, Teams and GoToMeeting use it as a video source. The SC5C0N4 HDMI is the four-channel HDMI card at 1080p60, and the SC5A0N8 HDMI doubles the count to eight HDMI channels at 1080p30.

On the operating system side Yuan supports Windows 7, 8, 8.1 and 10, 32-bit and 64-bit Linux from kernel 2.6.14, Linux on ARM, and NVIDIA Jetson TX2, Nano, AGX Xavier and Xavier NX modules. So four-channel recording can run on a Windows PC, a Linux server or a Jetson edge unit. The board measures 167.65 x 93.05 mm.
