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.
Recordings that are larger than 4GB will take a long time to buffer and cannot be downloaded.
Workaround: Split the ARF file into 2 or more files and then convert them.
- Log into your Webex site. (Example: SITENAME.Webex.com)
- Click on My Webex in the top navigation bar.
- Click on the My Recordings tab.
- Select the Recording you want to split.
- Click the Modify button.
- Add the text Part1 to the end of the Topic.
- Within the Playback control box, select Partial playback.
- Look at your total recording time (Example 2 hours) and make the end time to be half of the total time (Example: 1:00:00).
- Select Save.
- On the right side of the page, Select 'If you want to download the recording, click here.'
- Download the recording.
- You should now be able to open the recording and convert it to MP4.
- Repeat steps 2 - 12, but for step 7, Topic add the text Part2, then for Step 9 have the start time begin where you left off in Part 1 (Example: 1:00:01).
- Once you have downloaded the (2) smaller recording files and converted them to MP4, you can use a 3rd party MP4 joiner to combine the files back into one file.
