This repository contains mathematical animations illustrating concepts in statistical auditing made using manim, which is an animation engine for explanatory math videos.
To render the videos on your own computer, make sure that you have a working version of manim for Python 3.12. See this page for install instructions. We also use manim voiceover (with coqui-tts for Python 3.12) for adding AI generated voiceovers, so make sure to install that as well.
If you have a working setup and a Python file containing a scene named NameOfScene.py, open a terminal in the project folder and type the following command. Once executed, this will render the scene in low quality (-ql) and will preview it in the default video player when it is finished (-p).
manim -ql -p NameOfScene.py
Concatenating all high quality scenes into a full movie can be done using moviepy. To do so, open a terminal in the project folder and simply type the following command.
python3 _montage.py
The script will take care of everyting and produce an .mp4 file called Video.mp4. Note that it is important that your files start with [scene number]_SceneName so that the script can place them in the right order. For example, the title card is typically named 00_Title.py and the next scene 01_SceneName.py.
