Switching Majors/Adding Minors at UC Davis

So I’m entering UC Davis as a Religious Studies major, but I want to change my major to Cinema-Digital Media. I can’t switch majors until after the first quarter, so will I be off track to finish in 4 years? Also, will the quarter taken for Religious Studies make me exceed the maximum unit count if I want to add a double major and/or minor eventually?

And I didn’t mean to put this in financial aid section I apologize
