Hi @mfishburn ,
Thanks for posting your question in the Webex Community. Glad to have you here.
You can use the Webex Recording Editor or Webex Recording converter as mentioned in this doc - https://www.webex.com/video-recording.html
You can trim it down to save space, or you can convert it to a WMV (which may be a smaller file size compared to WRF) and edit it like any normal video.
If you have any other questions, feel free to post them here in the community. Cheers!
