Sample animation generation using Manim

Manim-Test

Installation

pycairo and ffmpeg must be installed globally for manim to function properly.

brew install py3cairo ffmpeg

Apple Silicon machines require the following additional dependencies:

brew install pango scipy

Once installed, this project can be set up as any other venv-based project.

python3 -m venv venv
source venv/bin/activate
pip install -r requirements.txt

Usage

maze.py generates the sample animation. It should be run as

manim -ql --disable_caching --format png maze.py MazeScene

This instructs manim to use lower-quality animations (-ql), disable caching (--disable_caching), and output the animation as a series of PNG files (--format png). The resulting images will be placed in media/images/maze/ named like MazeSceneNNNN.png.

make_anim.py takes a collection of PNG images and combines them into an animated webp file, looking for frames that are identical, and using frame duration to minimize file size. It should be run as

python make_anim.py media/images/maze/MazeScene

This will generate the animation from the files matching the given pattern. With no options, it will assume the desired output is 15 FPS with high compression. The resulting animation will be written to out.webp. For more options, run python make_anim.py --help.

usage: make_anim.py [-h] [-f fps] [-q] [-o output_file] file_base

positional arguments:
  file_base       e.g., "media/images/maze/MazeScene"

options:
  -h, --help      show this help message and exit
  -f fps          Sets the output frames per second to fps. If omitted, assumes
                  15.
  -q              Uses higher-quality compression. Defaults to low quality.
  -o output_file  Output file for the animation. Must be a webp file. Defaults to
                  out.webp

manim renders PNG images to
      media/images/<scene_filename>/<scene_classname>NNNN.png

This script uses file globbing to find all numbered frames, so the numeric part
and file extension are not needed.

Be sure to clear out frames between runs, or frames from various renders could
end up in the same animation.
