LESSON 01 · 4 MIN READ
How the workflow works
Prompts, skills and the engine: what each one does and what a finished video takes.
In this lesson
- →The difference between a prompt and a skill
- →What Claude builds and what you bring
- →How long a first video really takes
Every video on Get Up Inside is built in code by Claude Code: the world, the characters, the camera, the captions and the sound. Nothing is filmed and no video AI is used, so characters stay identical in every shot, text is always readable and you can render as often as you like for free.
The three pieces
- The engine: a three.js renderer that runs in Chrome on your computer and turns a scene file into an MP4. It ships inside every skill.
- A skill: a folder of instructions and references that teaches Claude Code our whole workflow for one style (3D Story, Motion Explainer or Family Story). Install it once and Claude knows how to build any video in that style.
- A prompt: the recipe for one specific video from the library: the story, every scene with timecodes, the voice lines, captions and sound. Paste it with the skill installed and you get that video, ready to change into your own.
What you bring
- A computer (Mac or Windows) with Claude Code on a paid Claude plan.
- A voice: your own recording, or a text-to-speech tool. A free offline voice is included.
- Your idea, or a prompt from the library to start from.
What a first video really takes
Setup is a one-time job of about 30 minutes. After that, a 30–60 second Short usually takes an hour or two: about 20 minutes for script and voice, 30 minutes of building and checking stills with Claude, and 10–20 minutes of rendering while you do something else. Your second video is much faster, because you already know the steps.
Tip: Start with a prompt from the library rather than a blank page. You will see how a finished video is put together, and you can change the story once it renders.
