Magewell Ultra Encode SDI Plus

SDI Hardware Encoder with SRT Encryption and Full NDI Output

The Magewell Ultra Encode SDI Plus is the enhanced variant of the Ultra Encode SDI, adding SRT with AES encryption, full NDI output, and expanded streaming protocol support to the standalone SDI encoding appliance. At £440, it is aimed at broadcast environments where SDI is the signal standard and where security, NDI integration, or contribution-grade streaming protocols are part of the specification rather than optional considerations.

What It Does

The Ultra Encode SDI Plus accepts SD-SDI, HD-SDI, and 3G-SDI video sources and encodes them to H.264 or H.265 at up to 1080p60 for delivery over IP. Output options include RTMP, RTSP, SRT with AES encryption, NDI, and HLS. The device operates as a fully standalone appliance with web-based management and no requirement for a host PC. It is the natural choice for broadcast SDI environments that need to add IP streaming capability with the full protocol flexibility the Plus firmware provides.

Who Needs This

• Broadcast facilities streaming SDI programme output to online platforms over public internet connections, where SRT encryption protects the contribution feed from interception
• Production companies building NDI-based workflows who need to bring broadcast SDI cameras into the network as full NDI sources without a separate converter device
• Sports broadcasters and outside broadcast companies requiring reliable, encrypted SRT contribution from fixed camera positions over public or shared networks
• Any broadcast installation where the standard Ultra Encode SDI protocol set falls short of the streaming destination requirements or the organisation security policy

Key Technical Capabilities

• SDI input: SD-SDI, HD-SDI, 3G-SDI
• H.264 and H.265 encoding up to 1080p60
• SRT output with AES encryption
• Full NDI output
• RTMP, RTSP, HLS output
• Enhanced streaming targets and configuration vs standard model
• Gigabit Ethernet, PoE powered option
• Web-based management interface
• Fully standalone, no PC required

Standard SDI vs SDI Plus: Which to Specify

The standard Ultra Encode SDI at £369 covers most streaming requirements from SDI sources: RTMP to platforms, RTSP for internal distribution, SRT for low-latency delivery, NDI for production network integration. The Plus at £440 adds encrypted SRT and richer NDI support for deployments where those capabilities are required by the destination system or mandated by a security policy. The £71 uplift is straightforward to justify when either of those requirements is on the specification sheet. For HDMI source environments needing the same enhanced protocols, the Ultra Encode HDMI Plus is available at the same price.
