i uploaded videos i recorded to iCloud and cannot download them to my iPad ret display… how can I do this?

i recorded a few videos I stored temporarily in my iPad. Now I want to download some of them for an iMovie project I am working on but I cannot find a way to do it. I have a Mac and have connected the iPad and even accessed the photo stream where the videos are stored. The photos are shown in the Mac but not the videos. How can I gain access to my videos so I can choose which one to download? Where can I see them in iCloud, once I log in?
