This book is designed to address anyone who is just above the “raw beginner” level. This book will explain some basic process such as entering commands and execute simple code instructions using a Command-Line- Interface (CLI) instead of using high resource-intensive Graphical User Interfaces (GUI). You may review some basic definitions and concepts, or skip directly to the working Formulas, as you'll prefer. It is a book intended for both the beginner and the expert developer, but suitable also for creatives, social media managers, webmasters, writers, musicians, photographers, video-makers, audio engineers, archival and restoration technicians, radio/tv broadcasters, streamers, You-Tubers, etc. and anyone who needs to automate and speed-up the manipulation, editing and conversion of many different audio/video/pictures formats. What's the difference between this book and other basic books about FFMPEG? FFMPEG has a pretty steep learning curve and the books currently around lacks on the very basics terms and syntax explanations of the commands. This book contains lots of explanations about the basic BASH terms, which unleash the functionalities and the true power of FFMPEG. Also: this book will cover other great tools for content creation, editing and automation, such as ImageMagick, Bento4, Ghostscript along with scripting automation formulas and examples. Why a book on the basics of FFMPEG? Because FFMPEG can be powerful and can be very easy for anyone, once it's core technology and syntax are understood. If you would like to know more about a ultra-fast way that gives you for free the same results that you achieve with expensive subscription-based softwares for content creation/video editing/image or audio manipulation/conversion, then this is the right book for you.
