Transitions Between External SWFs - looks crap as the size of external SWFs grow

regarding this tutorial I started my site ( to get some trasition effects but im getting somewhat different since the external SWFs take time to load. isn’t it better to create “intro and outro” on the same time line instead of loading external SWFs bcos once the movie loaded as a whole will lead to smooth and contineous transitions. If anyone ever did something better or how can I use some transition effects (like intro and outro) without using external SWFs ? is my current problem.
