    Video with a high level of motion and high resolution, such as sporting events, requires a higher bitrate. By default, Pearl Nexus automatically uses the incoming video source frame size as the frame size for streaming and recording when the channel has only one layout with a single video source. If you're channel has multiple video sources or layouts, you must manually set a frame size for the channel.
  • Page 154 Instead of using the same frame size as the original video source, you can configure a smaller frame size for the channel and let Pearl Nexus downscale the video. For example, if the input video signal resolution is 1920×1080 (a 16:9 aspect ratio) and the channel's frame size is set to 1280×720, Pearl Nexus downscales the video and streams/records the channel at the lower frame size, using less bandwidth and producing smaller recorded files.
