  • After purchasing, please back up the NDI authorization code, one code per machine to avoid loss.
  • You can also use NDI DEMO without purchasing an NDI license. It can be used for 30 minutes after startup, and the screen will be black after 30 minutes. and it can be used again for 30 minutes after restarting.

Introduction

LinkPi UVC2 is the swiss-army knife for mobile creators. Slide it between any HDMI and USB-C source and you get a bidirectional, driver-free bridge that captures or outputs 4K30 video in real time. A dedicated H.264/H.265 encoder inside compresses up to 16 Mb/s while keeping your laptop free for editing or mixing. Choose SRT for reliable remote contribution, RTMP for social platforms, or NDI|HX2 for IP-based studio workflows—all configured in seconds via the built-in web UI. Whether you need to turn your GoPro into a clean HDMI feed for ATEM or bring a 4K camera signal into OBS, the UVC2 delivers broadcast-grade quality from a pocket-sized box.
