Suggested stream settings
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.
The following table provides suggested settings to maximize your video quality while minimizing system
resource usage when streaming video content from your Pearl-2.
