Here's a free class I taught on green screen. It was sponsored by Tiffen who sell a great keyer I use called Zmatte…. but the class has benefits for all users.
Greenscreen has become an essential tool in modern video and film workflows. This webinar features visual FX industry veteran Marco Paolini and Motion Graphic Designer and Editor Richard Harrington. You'll learn modern shooting advice to produce better keying footage (particularly the need for quality lighting) as well as on-set advice to follow. You'll then explore how to prepare background plates, generate multiple mattes, wrap the light and more. This workshop will teach you techniques that work with any post workflow and also gives you a quick start on successfully keying with zMatte.
