Maximum bitrate (MBR)
With maximum bitrate, you can set a target bitrate to handle bitrate limitations in your system. You may see a decline in image
quality or frame rate when the instantaneous bitrate is kept below the specified target bitrate. You can choose to either prioritize
image quality or frame rate. We recommend that you configure the target bitrate to a higher value than the expected bitrate. This
gives you a margin for additional complexity that needs to be captured.

Average bitrate (ABR)
With average bitrate, the bitrate is automatically adjusted over a longer timescale. This is so you can meet the specified target and
provide the best video quality based on your available storage. Bitrate is higher in scenes with a lot of activity, compared to static
scenes. You are more likely to get better image quality when needed when using the average bitrate option. You can define the total
storage required to store the video stream for a specified amount of time (retention time) when image quality is adjusted to meet the
specified target bitrate. Specify the average bitrate settings in one of the following ways:
• To calculate the estimated storage need, set the target bitrate and the retention time.
• To calculate the average bitrate, based on available storage and required retention time, use the target bitrate calculator.
