matplotlib.animation.MovieWriter   classmatplotlib.animation.MovieWriter(fps=5, codec=None, bitrate=None, extra_args=None, metadata=None)[source]
 
Base class for writing movies. This is a base class for MovieWriter subclasses that write a movie frame data to a pipe. You cannot instantiate this class directly. See examples for how to use its subclasses.  Attributes 
 
frame_formatstr


The format used in writing frame data, defaults to 'rgba'.  
figFigure


The figure to capture data from. This must be provided by the sub-classes.      Parameters 
 
fpsint, default: 5


Movie frame rate (per second).  
codecstr or None, default: rcParams["animation.codec"] (default: 'h264')


The codec to use.  
bitrateint, default: rcParams["animation.bitrate"] (default: -1)


The bitrate of the movie, in kilobits per second. Higher values means higher quality movies, but increase the file size. A value of -1 lets the underlying movie encoder select the bitrate.  
extra_argslist of str or None, optional


Extra command-line arguments passed to the underlying movie encoder. The default, None, means to use rcParams["animation.[name-of-encoder]_args"] for the builtin writers.  
metadatadict[str, str], default: {}


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.       __init__(fps=5, codec=None, bitrate=None, extra_args=None, metadata=None)[source]
 
 Parameters 
 
fpsint, default: 5


Movie frame rate (per second).  
codecstr or None, default: rcParams["animation.codec"] (default: 'h264')


The codec to use.  
bitrateint, default: rcParams["animation.bitrate"] (default: -1)


The bitrate of the movie, in kilobits per second. Higher values means higher quality movies, but increase the file size. A value of -1 lets the underlying movie encoder select the bitrate.  
extra_argslist of str or None, optional


Extra command-line arguments passed to the underlying movie encoder. The default, None, means to use rcParams["animation.[name-of-encoder]_args"] for the builtin writers.  
metadatadict[str, str], default: {}


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.     
 Methods  
__init__([fps, codec, bitrate, extra_args, ...]) 
 Parameters    
bin_path() Return the binary path to the commandline tool used by a specific subclass.  
cleanup() [Deprecated]  
finish() Finish any processing for writing the movie.  
grab_frame(**savefig_kwargs) Grab the image information from the figure and save as a movie frame.  
isAvailable() Return whether a MovieWriter subclass is actually available.  
saving(fig, outfile, dpi, *args, **kwargs) Context manager to facilitate writing the movie file.  
setup(fig, outfile[, dpi]) Setup for writing the movie file.   Attributes  
frame_size A tuple (width, height) in pixels of a movie frame.  
supported_formats      classmethodbin_path()[source]
 
Return the binary path to the commandline tool used by a specific subclass. This is a class method so that the tool can be looked for before making a particular MovieWriter subclass available. 
   cleanup()[source]
 
[Deprecated] Notes  Deprecated since version 3.4:   
   finish()[source]
 
Finish any processing for writing the movie. 
   grab_frame(**savefig_kwargs)[source]
 
Grab the image information from the figure and save as a movie frame. All keyword arguments in savefig_kwargs are passed on to the savefig call that saves the figure. 
   classmethodisAvailable()[source]
 
Return whether a MovieWriter subclass is actually available. 
   setup(fig, outfile, dpi=None)[source]
 
Setup for writing the movie file.  Parameters 
 
figFigure


The figure object that contains the information for frames.  
outfilestr


The filename of the resulting movie file.  
dpifloat, default: fig.dpi


The DPI (or resolution) for the file. This controls the size in pixels of the resulting movie file.     
   supported_formats=['rgba']
