Timing sync'

I have a movie made in flash that has a .mp3 file that plays with it. my animations are at the right points in the presentation, but when i export it, it always seems to be off time once i’m about 1 minute in.

The mp3 is attached right now, is this the best way to have it? And any thoughts why it gets of time as the movie plays?


depending on how fast ur computer is it can vary. also try setting it to a different “sync”
