I've never used iVideo, so I did some looking around to try to find an answer to your question. The best I could come up with, short of installing the software and trying it out myself, is that it seems you have to upload/share the videos from iVideo to another site (Facebook, Vine, Instagram, etc.) to share them. Since iVideo vids are also autosaved to iCloud, that might be an easier option for sharing. Sorry not to be of more help, but I didn't see a way to share directly from iVideo to other people.
