MP4 Recordings Default in Webex Meetings 40.10
In the upcoming October (40.10) update, all-new recordings in Webex Meetings will be stored in MP4 format, either in the cloud or locally as selected at the site or host level, with a video-centric experience. By standardizing the recording format, you'll have a wider choice of playback tools, better security, and a more effortless collaboration experience even after your meetings. Existing ARF and WRF recordings can still be downloaded or played at the Webex site.
