Who this book is for

In plain words: AI video tools turn a text prompt or a photo into video. This book shows which tool to use, what it really costs, and what you may legally publish.

  • Marketers and creators making social clips, ads and explainers
  • Founders replacing stock footage or a studio
  • Developers who want to call video models from code
  • Not for: Not for you if you want to learn classic video editing software.

Which tool should you use, what does a usable clip really cost, and why does your character change face between shots? This visual beginner's guide answers all three. Inside, you will learn to understand how video models work, and why the same prompt gives a different clip each time; write prompts in shot language: shot size, camera move, one action, length; keep one character consistent across every shot with reference images; add a voice, lip sync and captions that stay the same from clip to clip; make talking head and avatar videos, then edit one master file for every platform; and price any job by its cost per usable second, failed takes included. Fourteen chapters, 40 diagrams and 23 step by step recipes. Every idea has a diagram, every recipe is numbered with the result you should see, and every chapter ends with a Try it to check yourself. The words stay plain, and the real terms stay in. Whether you are a marketer, a creator, a trainer or a founder, you finish with a short ad you can publish, and you know the rules on rights, consent for real faces and voices, and AI labels.
