Blackmagic Web Presenter 4K

Web Presenter 4K is a hardware streaming encoder with a 12G-SDI input that takes HD and Ultra HD sources up to 2160p60, plus a 12G-SDI loop output and SDI and HDMI monitor outputs. It streams over its gigabit Ethernet port using RTMP or SRT, can tether a 4G or 5G phone over USB as a backup connection, and also appears to a computer as a USB-C webcam. Blackmagic has since renamed it Streaming Encoder 4K. It takes the streaming PC out of the chain: feed it the programme from a switcher, load the platform and stream key, and go on air from the front panel. Power comes from an internal AC supply, with a 4-pin XLR 12V input for battery or backup power. At one-third rack width it sits beside a switcher, and the loop output lets a second unit send the same feed to another platform.
