For EDCI 352 we were required to create a video introducing who we were with the intended audience being students we would be working with on a project.  I had not made a video like this before and during the time creating it I learned about video and audio editing through  iMovie.  Thankfully there are many tutorials online that help with explaining the program!  We also had a class on video/audio editing for EDCI 336 which was very helpful (unfortunately after my video was due!) during which we learned how to incorporate green screens into our videos.  The sample lesson incorporated creating a video with chickens pecking around under the water in a coral reef-which utilized a green screen.  There is a green screen at the university library which I did not know existed!
