'''Advanced Recording Format''' ('''ARF''') is a proprietary video container format used to store recordings created by Webex, a video conferencing program used mainly in business environments. It seems to have been intended to succeed [[Webex Recording Format]] (WRF), but they have coexisted; ARF is (as of 2019) only produced by recording software run directly by the company, while anyone that wants to produce their own recordings (eschewing the "cloud") must use software only capable of producing WRF<ref name="tools1">https://www.cisco.com/c/en/us/td/docs/collaboration/support_center/wbs30/WebEx_BK_SD927CB3_00_support-center-frequently-asked-questions/WebEx_BK_SD927CB3_00_support-center-frequently-asked-questions_chapter_01000.html → What tools does WebEx provide for recording, editing, and playing recordings?</ref>. The process of producing recordings on the company's servers is called "Network-Based Recording" in documentation<ref name="tools1" />, and the format occasionally<ref>E.g. https://welcome.webex.com/client/T33L/nbr2player.msi, the ARF player linked from https://www.webex.com/video-recording.html</ref> seems to be called '''NBR2'''. It appears to have a different internal structure from WRF and its predecessor [[WOT]]. It is presumably a container format, like WRF (and possibly WOT). In addition to video and audio, it captures text chat and other peripheral types of data.<ref>https://www.cisco.com/c/en/us/td/docs/collaboration/support_center/wbs30/WebEx_BK_SD927CB3_00_support-center-frequently-asked-questions/WebEx_BK_SD927CB3_00_support-center-frequently-asked-questions_chapter_01000.html → Does network-based recording capture all the content of the meeting?</ref>
