I have iMovie 11 and was wondering if someone can explain to me the difference in finalizing a project vs sharing a project. It seems that when I share a project to iTunes, I can select the sizes to fit the product that I eventually will watch the video on. Sharing also seems to be a fairly quick process. Finalizing a project on the hand seems to take a very long time and it doesn't appear that I can select which sizes I finalize the video in. Can someone explain to me what the difference is? Also, after I share or finalize my project, how do I remove the project from the "project" area of iMovie or is it going to be there forever? And if I do remove it, does it affect the shared or finalized project?
