If you’ve ever watched a math-related video online and come away not only enlightened but also visually mesmerized, there’s a good chance you were watching content by 3Blue1Brown, the beloved YouTube channel run by Grant Sanderson. Best known for its elegant, eye-catching animations and intuitive explanations of complex mathematical ideas, 3Blue1Brown has revolutionized how people perceive and learn math. But one of the most frequently asked questions by intrigued viewers and aspiring creators alike is: What tools does 3Blue1Brown use to make his videos?

Unlike most educational YouTubers who may rely on slide presentations or simple visuals, 3Blue1Brown videos are almost entirely animated with a unique, flowing style. The secret behind this captivating presentation lies in a custom-designed animation engine called manim, short for “Mathematical Animation Engine.”

The Core Tool: Manim

Manim is a Python-based animation library specifically designed for creating precise and beautiful mathematical animations. Grant Sanderson himself originally developed the library to meet his own needs when producing visual explanations. It allows for highly controlled visuals, including the ability to animate formulas, plots, geometric shapes, and transformations.

One of the advantages of using Manim is its script-based control. Animations are created entirely via code, enabling a level of customization and mathematical accuracy that’s nearly impossible with traditional video-editing software.

Over the years, Manim has evolved significantly. The original version of Manim, now referred to as manim-old or manim3b1b, is specific to the structure 3Blue1Brown uses. However, a community-maintained, open-source version known as manimCE (Manim Community Edition) has also gained popularity, making it more accessible to aspiring animators and educators.

Programming and Scripting

Since Manim is built with Python, a large portion of video creation involves programming the scenes using Python scripts. Grant writes modular scripts to define the sequence of animations—text builds, movement of shapes, dynamic graphs, and more.

This process requires not only a deep understanding of mathematics but also programming proficiency. It’s a technical but rewarding approach that ultimately gives each video its signature style and clarity.

Audio Production and Voiceover

Along with visuals, 3Blue1Brown videos are known for their calm, clear, and contemplative narration. For this, Grant records his voice using a high-quality microphone, such as the Shure SM7B, and processes the audio using software like Adobe Audition or Audacity.

The audio is carefully synchronized with animated visuals, often with multiple takes to match timing perfectly. The blend of excellent visuals and clean narration creates a seamless learning experience.

Video Editing and Rendering

After generating scenes via Manim code and recording narration, the final step involves assembling the clips together. Grant uses video editing tools like Adobe Premiere Pro to sync the animations with the audio and to add finishing touches such as transitions, titles, and background music—though music is used sparingly in most cases.

Hardware and Workflow Efficiency

Because generating high-resolution animations can be resource-intensive, 3Blue1Brown’s setup includes a powerful computer with a fast CPU and GPU to speed up rendering times. Manim’s rendering can support parallel processing, which allows for multiple frames to be rendered simultaneously, further boosting efficiency.

FAQs

  • Q: Can anyone use Manim to create similar videos?
    A: Yes! Manim is open-source, and anyone can use and contribute to it. The Manim Community Edition is an excellent place to start for beginners.
  • Q: Is prior programming experience required to use Manim?
    A: Yes, since it’s a script-based tool, knowledge of Python is essential. However, there are many tutorials available to help beginners.
  • Q: Where can I find the Manim library?
    A: Manim’s code is available on GitHub. The original 3Blue1Brown version and the Community Edition each have their own repositories.
  • Q: What makes 3Blue1Brown’s videos unique from other math channels?
    A: The unique visual style enabled by Manim, combined with deep mathematical insight and clear narration, makes the videos stand out.
  • Q: Does Grant work alone on the channel?
    A: Mostly, yes, although he has sometimes collaborated with others for certain topics or animations.

In conclusion, 3Blue1Brown’s videos are the result of a finely tuned balance between code, creativity, and mathematics. The use of unique tools like Manim not only brings abstract concepts to life but also inspires the next generation of creators to blend math and art in innovative ways.
