Calculate the disk space a recording takes at a given bitrate and length.
Bitrate is a flow of bits each second, so the file size multiplies that flow by the duration and divides the kilobits into megabytes. Session backups and archive drives fill fast at high bitrates, so size planning prevents running out mid-recording.

Size (MB) = duration x bitrate x 60 / 8000

This calculator takes 2 inputs: Duration, Bitrate. The pre-filled defaults are a realistic starting point — replace them with figures from your own environment for a result you can act on.
