Hit area for animated buttons

Hi Everyone!

I’ve made my mc clip as a button - but the hit area is so small that the finger keeps missing it. I know you can draw your own ‘hit’ area for the button symbol - but how would I do that if I’m actually using a movie-clip as my button?

Thanks in advance guys!

I’m a noobie - I just figured out how to make my movie into a button ~ yay
