We got some new toys this year in the Video Arts Department and we've been having fun with them in a couple of different ways. We've been doing some green-screen production in the advanced class (Video for TV), and are just starting to introduce it to a couple of the intro classes.Working with a green screen is not easy, and there are two aspects that need to be learned - the actual production and the post production. It's important when setting up the green screen to light the screen evenly to ensure an even shade of green. You must also light the subject well, to provide for a realistic image when you superimpose it over the background. Lastly, you need to be sure that your subject is not wearing clothing or jewelry - or even tattoos - that are the same color as the background (you can see in one of our examples, a student with a cyan shirt that appeared blue actually had enough green in it to become semi-transparent).
In post production, we use Final Cut Pro to "key" out the green of the background. This is not as easy as it sounds. Ask any professional, chroma keying is a skill that takes lots and lots of practice, there is not a concrete recipe for success.
With that being said - I think our students did a pretty good job learning the basics of this technique. Take a look at the results:
