Video with background

Today we learned how to edit out a green screen to put a picture behind the object of our video. I found it very interesting to play with the green removal options and the softening effects when the green taken away causes jagged lines and edges. I didn't think this would be useful knowledge, but as I do more research for my area of study (advertising) I realize that I will need all the skills I am learning to be a diverse and useful employee to any firm I may join.
