'''Saves a movie file by drawing every frame.
Parameters
----------
filename : str
The output filename, e.g., :file:`mymovie.mp4`.
writer : :class:`MovieWriter` or str, optional
A `MovieWriter` instance to use or a key that identifies a
class to use, such as 'ffmpeg'. If ``None``, defaults to
:rc:`animation.writer`.
fps : number, optional
Frames per second in the movie. Defaults to ``None``, which will use
the animation's specified interval to set the frames per second.
dpi : number, optional
Controls the dots per inch for the movie frames. This combined with
the figure's size in inches controls the size of the movie. If
``None``, defaults to :rc:`savefig.dpi`.
codec : str, optional
The video codec to be used. Not all codecs are supported
by a given :class:`MovieWriter`. If ``None``, default to
:rc:`animation.codec`.
bitrate : number, optional
Specifies the number of bits used per second in the compressed
movie, in kilobits per second. A higher number means a higher
quality movie, but at the cost of increased file size. If ``None``,
defaults to :rc:`animation.bitrate`.
extra_args : list, optional
List of extra string arguments to be passed to the underlying movie
utility. If ``None``, defaults to :rc:`animation.extra_args`.
metadata : Dict[str, str], optional
Dictionary of keys and values for metadata to include in
the output file. Some keys that may be of use include:
title, artist, genre, subject, copyright, srcform, comment.
extra_anim : list, optional
Additional `Animation` objects that should be included
in the saved movie file. These need to be from the same
`matplotlib.figure.Figure` instance. Also, animation frames will
just be simply combined, so there should be a 1:1 correspondence
between the frames from the different animations.
savefig_kwargs : dict, optional
Is a dictionary containing keyword arguments to be passed
on to the `savefig` command which is called repeatedly to
save the individual frames.
Notes
-----
fps, codec, bitrate, extra_args, metadata are used to
construct a :class:`MovieWriter` instance and can only be
passed if `writer` is a string. If they are passed as
non-`None` and ``writer`` is a :class:`MovieWriter`, a
`RuntimeError` will be raised.
