If you have not seen or used SIMPLE TRANSFER (iOS) it does what most of us have been frustrated with and want. You can move video from a computer to photos in the iPad, for use with iMovie, or just to have. You can do the reverse too. Any video in iPhoto on the iPad can be moved to the computer.
It’s free and its easy! The for fee moves multiple files but I use the free.
Thanks Cyndy Everest for sharing. It is $1.99 but I like it. Just tried moving a few things and it seems to work very well. So if you have been having this issue, this ust might be your solution!!
