Bringing concrete examples from industry to light, this book explains how to use Blender to create visual effects for video/film production. It supplies readers with a practical way to learn how to use Blender’s tools across a wide range of scenarios in video/film production, including setting up cameras on a stage, lighting, and other production processes.

Maintaining a focus on composition, the book not only explains how to use the most common tools, such as tracking, rendering, and compositing, but also explains how to deal with software limitations and sort out problems.

Since the best way to learn something is with a practical example, this book follows one of the author’s own projects, starting with how to prepare the elements that will be needed later on. The example illustrates how to use Blender tools and features for scene tracking, setup, rendering, masking, and other post-production functions—from start to finish in a professional workflow.

The book examines all the compositing nodes that can be used in Blender. It details time-saving tips, features such as the motion tracker, and rendering techniques so readers will have enough information to accomplish the most common tasks encountered in the creation of a professional visual effects composition.

By following the example project presented in the book, you will gain the practical understanding required to use Blender’s tools in the most common scenarios in video/film production. You will also gain industry insights into the limitations of the software and how to sort out the problematic scenarios that may come up through the various stages of your project.
