4K H.264 H.265 SRT RTMP streaming encoder - Blackmagic Design BLM-BDLKWEB/D/SED4K

Blackmagic Design Streaming Encoder 4K is a streaming processor designed to transmit HD and Ultra HD video using H.264 / H.265 compression standards via SRT and RTMP protocols, allowing you to broadcast live to platforms such as YouTube, Facebook, Twitch, X or the Blackmagic Cloud. Thanks to its 10/100/1000 Base-T Ethernet connection, it can transmit directly to the internet, while compatibility with 5G and 4G mobile networks means you can use a smartphone data connection for streaming if your internet connection drops. You can even choose whether to give priority to the ethernet connection or the phone connection. Based on a powerful hardware encoder, it includes a 12G-SDI reference input, which supports automatic video standards conversion, and a USB-C webcam port, which allows it to be used with video conferencing and streaming software. It also features an HDMI monitoring output so you can see the video feed in real time, and it supports 16 channels of embedded audio over SDI and 2 channels over HDMI. Blackmagic Streaming Encoder 4K makes it easy to create internet broadcast links with the Blackmagic Streaming Decoder 4K. This takes the H.264 or H.265 feed from the encoder and converts it to SDI and HDMI video so you can send video point to point between remote locations. The front control panel includes six buttons, a dial, and a 2.2" LCD display that lets you monitor video, audio, and streaming status. The device is compatible with Facebook, Twitch, YouTube, Twitter, Restream.IO, Vimeo, BoxCast, Castr, AfreecaTV, Bilibili, DouYu, Weibo, Zoom, Skype, Microsoft Teams, QuickTime Player, FaceTime, OBS Studio, Open Broadcaster, VLC, Wirecast Play, and Wowza Streaming Engine. It also supports remote camera control, color corrector, Tally, and Talkback, providing a complete solution for professional video production.
