Saving an animation

  run this example as a notebook — or grab the .ipynb (also linked at the bottom of the page)

To save an animation, simply add the save_path kwarg and specify the path where you want to save the movie, including the extension. NOTE: saving to .mp4 (or .mov/.avi) uses matplotlib’s ffmpeg writer, so ffmpeg must be installed and on your PATH for those formats; .gif and animated .png exports are written with Pillow and need no external tools.
