Stream settings for video and slides
Stream setup is 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. For fast moving video, choose a higher bitrate
and frame rate. If you're streaming a slide presentation, you can save bandwidth and system processing by
lowering the bitrate and frame rate.
The following table provides suggested settings to maximize your video quality while minimizing system
resource usage when streaming video content from your Pearl Mini.
