    PART 2: Capture Capturing is the process of taking the signals from your video and audio sources and encoding them so they're ready for streaming and recording. You add the captured video and audio to channels, which you customize for live streaming, switching, and recording. This section covers how to create channels and add custom layouts so that you can capture, stream, and record exactly what you want - how you want! Whether that's a simple channel with a single video and audio source or channels that have multiple video and audio sources and custom layouts like picture in picture.

    What is a channel? Your video and audio sources that are connected to the input ports on Pearl-2 can be combined and added to channels, which you can stream and record. A channel is essentially an encoding instance that you associate with your video and audio inputs to produce outputs such as video recordings and streaming destinations.
