Ok, you need a fast computer so you won't be head banging all the time. xd
Step one, convert you'r pivot's into gif's....
ONE MORE THING IMPORTANT!!

PLEASE UNTICK THE MERGE BOX!!
Now select the actual size (or half) for the gif.
Yes I know you'r going to say ZOMG really?

Just do it and import it to WMM. (Windows Movie Maker duh...)
Drink milk(lol).
I'm sure you will be headbanging when you do that.
Drag em down!
If the animations are slow, right click the dragged clip and select video effects.
Oooh! choose the double speed effect!
Click OK!
Add songs? select timeline and drag the song to the space below the clips.
WTF? You should gimme the cookies before I drank the milk, OHH!!
