Yuan SC400N4 SDI PCIe SDI Frame Grabber with 4 x SDI Inputs at 1080p60

Multi-camera recording, whether for a live production, a sports analysis bench or a test cell, gets expensive in slots if each SDI camera needs its own card. The SC400N4 SDI is Yuan’s 4-channel PCIe SDI frame grabber for those systems, with four SDI inputs on one card.

Every channel captures at up to 1920 x 1080p at 60/50 fps, and the card also accepts 1080p30, 1080i, 720p and SD-SDI. Audio arrives as four 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 card runs PCIe x4 Gen2 and adds 16 GPIO lines. 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 SC410N4 6G-SDI moves each channel to 6G-SDI at 3840 x 2160 and 30 fps, and the SC400N4 M2 SDI puts four SDI inputs on an M.2 2280 module.

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 93.98 x 91.5 mm and is listed by Yuan as full height PCIe, for tower and rackmount hosts with a free x4 slot.
