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. For more information regarding video-centric recording, go to Video-Centric Network-Based MP4 Recordings in Webex Meetings and Webex Events.


There are three types of files for Webex recordings:

  • MP4
    • Newest recording format
    • Highest quality audio and video
    • Supported in Cisco Webex Meetings (WMS33.6 and later) and Events (WMS33.6 and later)
    • Can be played on any device that supports .MP4 playback including mobile devices
    • Can be edited in 3rd-party editors
  • Network-Based Recordings (NBR) - .ARF files
    • Generally higher quality video and audio than .WRF format
    • Most widely used and the default format in most meetings
    • Only created inside a Webex meeting, session or event
    • Records desktop, application share, and any other meeting content
    • Files cannot be directly edited but, start and end of playback can be truncated
  • Local or Standalone Recordings - .WRF files
    • Older format with fewer audio options
    • Generally lower quality audio and video than .ARF format
    • Files can be created outside of a meeting by any user with the Webex Recorder
