SWF export problem

Hi guys, I hope you can help me on this one.
When I export one of mine scenes to .swf (this scene is the only one which has transparency effects) and play it back it plays REALLY slow, like someone put a slow motion on it. What am I doing wrong?

I see,
Thanks Lilly

It’s probably just too heavy to play back in real time. If you have a swf file that has a lot of effects in it, then whatever browser you watch the movie in will have to load up the effects on each frame.

I don’t think there’s any way around it.
