    This effectively works as a slideshow input to ffmpeg with the fps passed as
    ``-framerate``, so see also `their notes on frame rates`_ for further details.

    Parameters
    ----------
    fps : int, default: 5
        Movie frame rate (frames per second).
    codec : str or None, default: :rc:`animation.codec`
        The codec to use for video compression.
    bitrate : int, default: :rc:`animation.bitrate`
        The bitrate of the movie, in kilobits per second. Higher values mean
        better quality at the cost of file size. A value of -1 lets ffmpeg choose.
    extra_args : list of str or None, optional
        Additional command-line arguments passed to ffmpeg.
        If None, uses :rc:`animation.ffmpeg_args`.
    metadata : dict of str, default: {}
        Metadata to embed in the output file. Possible keys include:
        'title', 'artist', 'genre', 'subject', 'copyright',
        'srcform', and 'comment'.
