A look at some variables that can negatively affect the quality of your stream.

Let’s look at some of the things that can negatively affect the quality of your stream.
Cameras typically do not have the same range of “vision” as the human eye.
They over-expose far before your eye would, and they can’t see the same levels of blacks that your eye can. So, your cameras need less variation in your lighting to create a nice picture. I.e., you need to have less contrast in your lighting.
You should make sure that the background of your stage, especially the space that you pick up when you’re zoomed in on the pastor for preaching, is appealing on video. A big, black hole isn’t great as a video background.
Your connection to your CDN needs to have dedicated bandwidth, and reliable bandwidth.
This is either through a separate internet connection, or through routers that can give priority to your stream’s upload and “starve” other internet users if needed to ensure that the stream bandwidth isn’t interrupted.
You don’t need a bunch of teens firing up their online games in the youth space taking down your service stream.
ISP needs to provide consistent, reliable service.
The biggest comment I’ve heard from people describing their streaming issues is having that reliable connection to their CDN.
A question posed to me from a previous article asked about dealing with audio dynamic range issues for their stream.
In the auditorium, you can have as much as a 30dB difference between the band and the spoken word. If you simply take the feed to your PA system and use that for your stream, when your viewers have the music at a reasonable listening level, the spoken word parts will be inaudible.
