ITunes :: Why Can't Import An IMovie Clip (.MOV)

After importing HD video (from a Canon Vixia HV40) into iMovie 11 (v 9.04) at 960x540 resolution, you get a bunch of .mov files. Does anyone know why those .mov files, as they come out of the import process,will not import into iTunes? Here are the details. My brother wanted to put a small one onto his iPad. I told him the simplest way (or so I thought) to do it would be to import the .mov file into iTunes (v 10.6.1) and then sync his iPad. There was no need to make a project from the single clip, then share it. However, iTunes will not import any of the .mov files made with the iMovie import. Does anyone know why? This happens on my iMac (core i7) and his (core i5). Of course, if I open the .mov file in QuickTime Player (v 10.1) then export to a .m4v file (export setting "iPad, iPhone & Apple TV"), the new file imports into iTunes just fine. In case iTunes thinks you shouldn't be importing clips from the iMovie events folder, I dragged the clip to the desktop and tried the import, but that did not work either. I guess what this comes down to is given that iMovie, QuickTime Player and iTunes all come from Apple, why can iMovie and QuickTime Player read the file while iTunes cannot? I would think the same code would be in all three products (do the iMovie and QuickTime Player developers refuse to share, while the iTunes developers are lazy?).
