Description:
In this series of lessons we will learn keit green screen, using multiple layers to capture as many details as possible. Using multiple layers and keyers, we will be able to focus our efforts and create a better final mask.
We will begin this project by importing the footage into NUKE and analysis of the work. Then we will create a garbage mask to divide the character into manageable pieces. Next we add Keylight effects to the layers to create the initial Kay. After that, we analyze the best way to remove noise on each layer. Then we will create a basic mask in alpha. Finally, we will focus on the hair and all the details related to rotoscoping and keying. We will complete this project creating a difficult rotoscoping bottle.
