The Magewell Ultra Stream SDI is the broadcast-signal version of the Ultra Stream appliance, accepting SDI video input and streaming it simultaneously to multiple online platforms without requiring a host PC. At £345, it is the straightforward SDI-to-platform solution for broadcast environments where the simplicity of the Ultra Stream control model matters as much as the signal compatibility. If you have an SDI source and need to get it live on YouTube and Facebook without a PC encoder in the chain, this is the device.
The Ultra Stream SDI takes an SDI video source and encodes it in H.264 for simultaneous streaming to YouTube Live, Facebook Live, Twitch, and custom RTMP destinations. Like its HDMI counterpart, it is operated through a touch interface or companion mobile app, designed for straightforward use by operators who need to go live reliably without deep technical configuration. The device is fully standalone, running without any attached computer once initial setup is complete.
The Ultra Stream SDI and Ultra Encode SDI occupy similar price points and both encode from SDI without a PC. The difference is depth versus simplicity. The Ultra Encode SDI at £369 is a full engineering device supporting H.265, SRT, RTSP, HLS, and NDI output alongside RTMP, with a detailed web management interface designed for AV engineers and IT administrators. The Ultra Stream SDI at £345 strips that back to the core platform streaming use case: RTMP to the major platforms, simple controls, and an operator-friendly interface for daily use. If the person running the stream is not a technical user, the Ultra Stream is the right specification. If you need SRT contribution, NDI output, or protocol flexibility beyond RTMP, specify the Ultra Encode SDI or Ultra Encode SDI Plus instead.
