Add live streaming to the internet to your video production setup using the Web Presenter 4K from Blackmagic Design. The Web Presenter 4K is a compact desktop device that allows you to connect any SDI video input and stream it live onto the Internet, using Ethernet or tethering via USB to your smartphone using a 5G or 4G connection. The SDI and HDMI monitor outputs allow you to see a wide range of live status information along with your broadcast.
The USB Type-C port allows you to connect any USB video source such as a webcam or computer, so it’s capable of broadcasting 4K video and audio on any webcam-compatible platform and software such as Skype, YouTube Live, Facebook Live, Twitch, Periscope, Teams, and more on Mac, Windows, Linux, and Chrome OS systems. It supports the H.264 codec and streams via RTMP and can stream in resolutions up to UHD 4K.
The SDI and HDMI monitor ports provide detailed status information on your feed, so you can monitor whether you are ON AIR as well as input status such as bit depth and stream quality, embedded audio input status, video and audio history, trend graphs, and video and audio meters. You can also see basic status information on the bright LCD screen on the front of the unit. There is also an SDI loop output for monitoring the original feed and sending it to a switcher or router.
The compact form factor allows you to fit it right into your broadcast setup, and it is compatible with optional rack shelfs in case you want to install it in a 1 RU rack. Its dual AC/DC redundant power input is handy in case you lose mains power and you can utilize the 4-pin XLR input for DC power. The Web Presenter 4K is also compatible with the Blackmagic ATEM Streaming Bridge to decode the streams back into HDMI or SDI signals for additional routing options.
