Frequently Asked Questions

There is a new FAQ section in the latest version of our documentation. This page here is intended for stashing new questions to be added to the documentation FAQ at some point (it is easier to edit the wiki than adding a PR).

Questions that have been added to the documentation should be removed from the entries below.

How to get video file output when I use the OpenGL renderer?

You need to use the --write_to_movie option. Note: at the moment, this option only works when passing it from the command line, setting it in a config file does not work. For more details see this issue.

How can I use a debugger (e.g., in VS Code or PyCharm) with my Manim scenes?

The easiest way of doing so is rendering your scene from within your Python file, that means: instead of running manim -qm -p my_file.py MyScene from the command line, call the Scene.render function directly from your file like this:

from manim import *

class MyScene(Scene):
    ...

with tempconfig({'quality': 'medium_quality', 'preview': True}):
    scene_object = MyScene()
    scene_object.render()

Then you can simply run the default Python debugger of your IDE on your file.
