Blackmagic Design Web Presenter 4K The Blackmagic Design Web Presenter 4K is a compact streaming processor built for broadcast-quality shows without a PC. Feed any camera or switcher via the 12G-SDI input, then publish directly to the internet with RTMP streaming or SRT streaming—including Ultra HD 2160p60. A built-in hardware encoder handles H.264/H.265 encoding for efficient, reliable delivery, while the front-panel technical monitoring display (2.2" LCD with status, meters, and trend graphs) keeps everything visible at a glance. For software platforms, the rear USB-C webcam output appears as a standard webcam up to 2160p60, so Zoom, Teams, and similar apps see pristine video without extra drivers. On the back panel, you’ll find SDI loop and HDMI/SDI monitoring outputs for a full-screen confidence view with data rate, cache, and audio details. Networking is straightforward with Ethernet streaming over 10/100/1000 Base-T, and you can tether a 5G/4G phone over USB when wired internet isn’t available. Installation is flexible thanks to the rackmount 1/3 RU form factor (1RU height), ideal for flypacks, studios, and control rooms. Power is equally versatile with internal 100–240V AC plus a 4-pin XLR +12V DC input for mobile or backup power scenarios. For accessibility and compliance, the unit supports embedding CEA-608/708 closed captions into RTMP streams. Whether you’re building a single-camera church stream, a corporate webinar hub, or a multi-camera studio handoff, Web Presenter 4K delivers the clean signal chain, professional monitoring, and platform flexibility demanded by a modern broadcast workflow.
