matplotlib.animation.FileMovieWriter   classmatplotlib.animation.FileMovieWriter(*args, **kwargs)[source]
 
MovieWriter for writing to individual files and stitching at the end. This must be sub-classed to be useful.  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__(*args, **kwargs)[source]
 
 Parameters 
 
fpsint, default: 5

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: {}

 Methods  
__init__(*args, **kwargs) 
 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, frame_prefix]) Setup for writing the movie file.   Attributes  
frame_format Format (png, jpeg, etc.) to use for saving the frames, which can be decided by the individual subclasses.  
frame_size A tuple (width, height) in pixels of a movie frame.  
supported_formats      finish()[source]
 
Finish any processing for writing the movie. 
   propertyframe_format
 
Format (png, jpeg, etc.) to use for saving the frames, which can be decided by the individual subclasses. 
   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. 
   setup(fig, outfile, dpi=None, frame_prefix=None)[source]
 
Setup for writing the movie file.  Parameters 
 
figFigure


The figure to grab the rendered frames from.  
outfilestr


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


The dpi of the output file. This, with the figure size, controls the size in pixels of the resulting movie file.  
frame_prefixstr, optional


The filename prefix to use for temporary files. If None (the default), files are written to a temporary directory which is deleted by cleanup; if not None, no temporary files are deleted.
