3/18/2020:  While the Coronavirus issues are in affect Live KH is specifying a maximum bitrate (bits transferred per second of video) of 1000 kbps, but most congregations stream using much less.  While a higher bitrate can result in higher quality video, it reduces the number of potential viewers, as some computers or Internet connections cannot handle higher bitrate video.  Moreover, a higher bitrate does not always result in better image quality.

There are good reasons to use a lower bitrate:

A lower bitrate often means a more stable connection, which translates into fewer problems for viewers.  The higher the bitrate, the faster and more stable your connection must be.  A video stream sends data continuously, so consistency and stability matter more than how fast the connection can be in short bursts.  If your encoder is trying to connect and then disconnects repeatedly or wont connect at all, then it is possible your bitrate is set too high.

The less movement there is in your broadcast, the lower the bitrate required for it to look good.  You can stream a kingdom hall meeting at 500-750 kbps and still display a great looking broadcast.
