matplotlib.animation.MovieWriter

class matplotlib.animation.MovieWriter(fps=5, codec=None, bitrate=None, extra_args=None, metadata=None)

Base class for writing movies.

This class is set up to provide for writing movie frame data to a pipe. See examples for how to use these classes.

Attributes

frame_format	(str) The format used in writing frame data, defaults to ‘rgba’
fig	(Figure) The figure to capture data from. This must be provided by the sub-classes.

Parameters:

fps: int

Framerate for movie.

codec: string or None, optional

The codec to use. If None (the default) the setting in the rcParam animation.codec is used.

bitrate: int or None, optional

The bitrate for the saved movie file, which is one way to control the output file size and quality. The default value is None, which uses the value stored in the rcParam animation.bitrate. A value of -1 implies that the bitrate should be determined automatically by the underlying utility.

extra_args: list of strings or None

A list of extra string arguments to be passed to the underlying movie utility. The default is None, which passes the additional arguments in the ‘animation.extra_args’ rcParam.

metadata: dict of string:string or None

A 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.
