Blackmagic Design Web Presenter HD — Used Professional Live Streaming Device

The Blackmagic Design Web Presenter HD is a professional all-in-one live streaming device that accepts SDI or HDMI video input and delivers broadcast-quality streams directly to platforms like YouTube Live, Facebook Live, Twitch, and more via RTMP over Ethernet. Compact and self-contained, it eliminates the need for a dedicated streaming PC, making it one of the most practical SDI streaming encoders available for live event and broadcast workflows.

For producers seeking the best professional live streaming device for YouTube or Facebook broadcasts, the Web Presenter HD stands apart by supporting mobile data streaming through a 5G or 4G phone connection — an invaluable backup when venue Ethernet is unreliable. Its USB-C webcam output also allows the unit to function as a plug-and-play webcam source inside Open Broadcaster Software, Skype, Wowza, and other major streaming applications, making it an ideal SDI to stream converter for live events of any scale.

Designed for broadcast-grade reliability, the Web Presenter HD handles HD and Ultra HD input standards — including 1080p, 720p, and 2160p across a wide range of frame rates — with SDI rates spanning 1.5G through 12G. Its built-in monitoring output with real-time audio metering, trend graphs, and a 2.2-inch color control display gives operators at-a-glance confidence during live productions. Closed caption pass-through support (CEA-608 and CEA-708) further extends its suitability for accessibility-compliant broadcast environments.
