def convert(input_path)
    ass_file = vtt_to_ass(input_path)
    if (not @output.nil?) then
        ass_file.write_to_file(@output + '/' + File.basename(input_path).gsub('.vtt', '.ass'))
    end
    puts ass_file.to_s unless @quiet
end

#start ⇒ Object

This method starts the application process. It sends the file_paths of VTT files in the input directory to convertFileToASS method and outputs the resulting ASS format to a new file.
