If you're just getting into Live Streaming on the Internet, here's a deal that expires on February 28th, 2017. You can get $100 off the Teradek Vidiu Wireless Streaming Encoder using this special link (here).
What is it and why would you need this? The Teradek Vidiu is a device that can sit on top of your camera and stream the HDMI output directly to the Internet up to 1080p. No computer needed, no OBS or Wirecast software required. The Teradek Vidiu is configured by adding in RTMP information (i.e. Facebook RTMP, YouTube RTMP, etc) and streams directly over your Wifi network.
But while the Teradek Vidiu can be hooked up to a single camera so you can be as mobile as you need, you can also attach this to the program feed output of your Live Switcher (i.e. ATEM). Most people (like myself) typically output to a computer through software like OBS or Wirecast. By connecting your Program Feed output you can eliminate that extra gear, bulk, and weight.
