The Importance of Transitions

What are three key new things about transitions that you learned from this video? Why did you find each of these interesting?

This video talks and explains about the type of transitions to have knowledge of that and know how to difference those. However some transitions that I find interesting were the common, cutaway and action transitions. Because I feel that those are so popular and being used by many people and in the majority of the movies, having a good effect of transition. 

In my own words I think that common transitions are those transitions, which are so popular and the firsts ones based on move onto another film and scene with like a fade in and fade out, black screen. Cutaway transitions are those that have effect of quick movement to pass to the other clip without noticing the change of scenario because of how it get combined with the other clip. And action transition are so common and most used on a video, connecting two shoots by matching the action at the end of each shoot.
