Crashes on iPhone 6

Every time I try to back up my info it backs up the contacts and pics, but it always crashes when it gets to the videos. Ive tried closing it and reopening it and it keeps crashing. I also got a notification saying that my info had been backed up in 6 weeks. So I did what it said and plugged it in, turned the wifi on and locked it and left it like that for a couple hours and it still didnt back my videos up.
