Tutorial Overview

Call it green-screen, blue-screen, or chroma-key, the technique of removing a solid color background so you can put your actors into an entirely different environment is a mainstay of effects today.

In this session, Larry Jordan shows you step-by-step techniques to create good looking keys using Final Cut Pro. Then, we’ll explore the power third-party keying software provides to take your keys to the next level. Along the way, Larry will illustrate key points to keep in mind during production to help make your keys look great — from picking the right video format to picking the right background.

NOTE: To make the most of this session, you should be running Final Cut Pro 6 or later. We illustrate how to use the keying software supplied inside Final Cut Pro, along with third-party plug-ins that provide even better results. Third-party plug-ins are sold separately.

Audience Level

This session is helpful to any Final Cut Pro editor looking to improve the quality of their keys. Familiarity with the Final Cut Pro interface, a basic knowledge of how to use filters, and access to green-screen footage will be helpful.
