Technical Considerations when Going Live

Internet Bandwidth

A wireless internet connection may be sufficient for streaming in many cases but a hard-wired ethernet connection to your computer will be the most robust if available. The maximum quality you can stream reliably will be limited to no more than about 75% of your internet connection upload speed. To determine the upload speed of your connection simply Google search “internet speed test” and they will give you a link that quickly determines your connection speed. Recommended video bitrates for streaming are listed below. Maximum streaming resolution varies by platform. 720p30 is the maximum allowed by Facebook and Zoom. YouTube allows live streaming up to 4kp60.

  • 4k/2160p @60fps: 20-51 Mbps
  • 4k/2160p @30fps: 13-34 Mbps
  • 1440p 60 fps: 9-18 Mbps
  • 1440p 30 fps: 6-13 Mbps
  • 1080p 60fps: 4.5-9 Mbps
  • 1080p 30fps: 3-6 Mbps
  • 720p 60fps: 2.25-6 Mbps
  • 720p 30fps: 1.5-4 Mbps

Signal Distribution (locally)

If you are displaying only to a local audience (in the same room), signal distribution to displays will be your focus. HDMI cables can be used to carry a signal up to 50ft, SDI cables up to 300ft. There are a variety of signal converters and distribution splitters available to broadcast one signal to multiple monitors or projectors. For example, here is a 4-way HDMI splitter.
