  """
      The default options for the faceswap Ffmpeg Writer plugin.
  
      Defaults files should be named <plugin_name>_defaults.py
      Any items placed into this file will automatically get added to the relevant config .ini files
      within the faceswap/config folder.
  
      The following variables should be defined:
          _HELPTEXT: A string describing what this plugin does
          _DEFAULTS: A dictionary containing the options, defaults and meta information. The
                     dictionary should be defined as:
                         {<option_name>: {<metadata>}}
  
                     <option_name> should always be lower text.
                     <metadata> dictionary requirements are listed below.
  
      The following keys are expected for the _DEFAULTS <metadata> dict:
          datatype:  [required] A python type class. This limits the type of data that can be
                     provided in the .ini file and ensures that the value is returned in the
                     correct type to faceswap. Valid datatypes are: <class 'int'>, <class 'float'>,
                     <class 'str'>, <class 'bool'>.
          default:   [required] The default value for this option.
          info:      [required] A string describing what this option does.
          choices:   [optional] If this option's datatype is of <class 'str'> then valid
                     selections can be defined here. This validates the option and also enables
                     a combobox / radio option in the GUI.
          gui_radio: [optional] If <choices> are defined, this indicates that the GUI should use
                     radio buttons rather than a combobox to display this option.
          min_max:   [partial] For <class 'int'> and <class 'float'> datatypes this is required
                     otherwise it is ignored. Should be a tuple of min and max accepted values.
                     This is used for controlling the GUI slider range. Values are not enforced.
          rounding:  [partial] For <class 'int'> and <class 'float'> datatypes this is
                     required otherwise it is ignored. Used for the GUI slider. For floats, this
                     is the number of decimal places to display. For ints this is the step size.
          fixed:     [optional] [train only]. Training configurations are fixed when the model is
                     created, and then reloaded from the state file. Marking an item as fixed=False
                     indicates that this value can be changed for existing models, and will override
                     the value saved in the state file with the updated value in config. If not
                     provided this will default to True.
