We have a new app that is doing well but we are certain that many users complete the registration and are then uncertain how to begin. We have created a support site with articles and walk throughts but really who has the time? I want to build compelling videos that explain the ideas and show some of the internals. I want them to be no more that 1-2 minutes. Ideally I am looking for tools that would allow me and others in the team to build the stories, add the static content and then animate the results in a compelling way that can be viewed on a phone.
