When you're setting up your live stream, you would typically consult your CDN or publishing destination for their
recommended settings to use.
Stream setup can be a matter of balancing quality and system resources. When choosing your stream settings,
it's important to consider the type of content you're streaming and the streaming protocol you've chosen.
For streaming fast moving video, a higher bitrate and frame rate delivers a better image. If you're streaming a
slide presentation, you can save bandwidth and system processing by lowering the bitrate and frame rate without
any noticeable image degradation.
