I'm learning Manim and I would like to know if it is possible to generate videos without the background.
I saw that you can define the background color in a extern file, but I don't know how to render the video without the background.
Can Manim render a video with transparent background?
Yes: simply pass the CLI flag -t (or its long form --transparent). Note that the default video file format does not support transparency, which is why Manim will output a .mov instead of a .mp4 when rendering with a transparent background. Other movie file formats that support transparency can be obtained by passing --format=webm or --format=gif.
