I used the search "rootstech 2016" to find these videos (https://www.youtube.com/results?search_query=rootstech+2016), but there may be others that did not include the year.
The live-streamed videos for each day are:
1) Thursday, 4 February:
2) Friday, 5 February 2016:
3) Saturday, 6 February 2016:
4) There are also individual videos for the Keynote talks (note that Doris Kearns Goodwin was not videoed).
5) There are some "Media Hub Video Booth" and "Sofa Talks" discussions - typically about 8 minutes long posted by the video host.
6) Then there are the random short subject videos posted by Expo Hall vendors or visitors.
Enjoy! It may take several weeks to watch everything! Eventually, the livestreamed class videos and other class videos will be available on the RootsTech.org pages.
