For standalone SuiteBox accounts, there is no limit to the length of the video recording. However, if the recording lasts longer than 2 hours (120 minutes), the session is recorded to multiple, consecutive MP4 files of up to 2 hours each in length until the archive is stopped.
For integrations such as xPlan, it depends on the downstream source. xPlan will support no-limit recordings but split into 2-hour recordings. Other integrations may support less.
