I know Im gonna get more replies on "use the search" but in my defence I did and I could not find something that is for real beginner like me.
First off I would really appreacite if someone can direct me to a link for video tutorial or something, I know there are tons of tutorials but I want to know the introduction, how to start etc.I also would like to know how the interface introduction of PI and how to integrate it with AE since most if not all of my graphics design comes from AE 7.0
Im using windowxp and not mac just incase it matters!
If you bought version 3 on CD, there is about 20 minutes of video tutorials to get you started. Online, the best stuff to get going is the on wondertouch's site under Support>Tutorials, then try the text tutorials "The Basics -- Adding emitters over background footage" and "Using particleIllusion with Adobe After Effects".
Aharon and I offer a two DVD training pack of video tutorials through the Creative Cow that covers just what you're asking for. You can find some more info on it in my signature below.
