Cannot access camera roll

Up to now, I managed to upload two videos from camera roll but now it is stuck:says no videos yet, and I need to access camera roll to upload from my iPad collection thru this iphone6s...and now, half an hour later, I get a video I have been trying to upload from photos getting sharing was interrupted messages a screen freezes. I still have to take and upload a video using capture but up to now I can only tell you that lately video uploads for me thru you tube are very frustrating, disgusting and unacceptable tasks!
