Blackmagic's Web Presenter 4K is a modern self-contained version of a broadcast television transmitter. It allows you to stream any SDI video input live on the Internet via Ethernet and/or via a USB-tethered smartphone 5G/4G connection. This complete streaming solution includes an advanced streaming engine that uses the H.264 codec and will stream via RTMP in resolutions up to 1080p60. Viewable via the 2.2LCD screen, you can also utilise BlackMagic's Web Presenter Utility software to monitor your output with video and audio meters, trend graphs, and SDI technical details. The built-in USB connections also allow this unit to be used as a webcam so you can use this with your computer to use with any streaming software or video-call programmes e.g. Skype or Zoom. This versatile unit is compatible with Mac, Windows, Linux, and Chrome OS systems.
