Folks,
there is an email exchange today on the Educause hybrid/online listserv regarding the use of easy video animation software for educational purposes:
http://blog.stcloudstate.edu/ims/2017/02/13/animation-for-education/
The choices so far are:
Camtasia (good, but pricy)
Xtranormal
Protago
All of the choices require license. I have added to the bottom of that blog entry a link to the IMS blog information (keyword to search the blog is “animation”), including Powtoon:

Powtoon still allows you limited, but free version of their application.
