A flash question
 

I want to upload some videos to my youtube account... So first I have to make some videos.
I'm trying to make something in flash that's just a song with a looping background animation (a little icon of me dancing to the song)
I want to loop the animation until the end of the song.
Do I need to cycle 1309 frames of the animation, or can I put it in a graphic somehow set to start at the beginning of the animation? :P
I have no idea XD

Anyone know where i can either find tutorials on how to do this, or can advise me?

here is one link I use, my skills are pretty rudimentary with flash.
