I know it's not After Effects, but this group has a lot of Mac users that might be able to help me.  My boss has an iPad2 with iMovie on it.  He's taken some footage he's shot and edited it down to about 35 minutes.  Now, he wants me to take his footage and put it in a project on my PC.  The problem is, there's not enough available room on the iPad to export the movie, and I can't upload it to YouTube.  I can copy the project file over to my PC, but Windows doesn't know what the hell this file is... any suggestions?
