Same thing has happened to me. Made a 3 min vid and no matter what size I choose to export, it just crashes. I power cycled the phone, but that didn't help. I was thinking about deleteing and de downloading, but I didn't want to lose my vid. I am hoping they would come out with an update so I don't have to make it all over again. I may just try though. Who knows when an update will be available, and there's no sense keeping a video I can't do anything with.
