Button Action

Hi there
I know this might seem like a basic request but I am lost… I tried a few things but couldn’t find a solution.

i want to create a button that has a movie that plays “on mouse over” and a movie that plays “on mouse out”

Basically the movie on mouse over is basically a fade in of some colour and the movie on mouse out is the fade out of the colour…

It just looks so much more smooth when done with both on mouse over and on mouse out…

Thanks gang!!
