Keying

I was given the job of keying for the footage with the green screen.
I went about this by importing the footage into Premiere Pro then added the effect "Ultra Key".
Using the eye dropper tool i selected the green background behind the person in the footage.  Then I started tweaking the settings until I had no green in the background then removed the spill on the subject.
Once I had completed all of the clips I added a white matt background on the layer below the subjects.
I then put all the footage in order in the timeline then exported the sequence. It was then given to Jess and Harrison who would then start the animation
