There is only one Optional Parameter:

  • Bitrate: That is the rate of compression of the resulting MP3 files. The higher the number, the better the quality and the larger the size. 48 kbit/s is a good compromise between these two factors.

Hit ‘Finish’ and run that job with Ctrl + F1

Please re-validate the result (see Transformation example one).
