I was interested in using motion graphics from WWW.video hive.net/category/motion-graphics in premier elements,
2 kinds specifically overlays for video and lower thirds. So I was wondering if there is anything I need to know in regards to file types that will or will not work in premier elements 11. Would there happen to maybe be any tutorials on this anywhere here?

The one I want to use the most is an overlay..
I'm assuming that all I have to do is just upload the file to premier elements and have 2 tracks one for the main video and one for the overlay, is this correct?
