Forum Question: Imovie responding slow:could beat markers,effects etc slow down imovie?

first of all,thank you macmost. I did what you suggested about experimenting with beat markers, and now I have it better under control.
But when I use in a four minutes long project, a lot of beat markers(120) and of course videos/fotos/effects, in some clips even slow motion or fast forward, my imovie11 is getting slow, not responsive almost stuck, when I work with this particular project.
Now my question is: is it because the many features in this project? Or maybe because my mac cant handle so much at once, is there a way to fix this issue?
My mac OS X is not even 4 months old, prozessor 3.06 GHz Intel Core i3 500Gb, version 10.6.6, with imovie11.

    The more effects and features you throw on to an iMovie project the more work you Mac has to do processing the real-time preview that you are seeing. For instance, showing video is the simplest. Then add a title. Then add a speed change. Then add a transition. Then add an effect. Etc. Eventually you will start to see performance suffer.
    Keep in mind that just a few years ago the idea of a consumer machine handling even simple standard definition video editing was out of the question.
    Try quitting all other applications and maybe a restart to see if that helps, at least for a little while. But it does sound like you are pushing the limits of your Mac and iMovie.
