HI, To become a music director you will have to cross various stages.
First get your basic degree in music and start to particpate in activities and programs. You can get into degrees associated with film scoring, composition, music business, music and entertainment industries or a related field.
Also learn music under any supervision so that you have an experience added as well.
Good Luck.
