So I'm getting a red Nokia Lumia 920 at the end of this month when I leave T-Mobile and I wanted to know what are the limitations on length of 1080p videos I can shoot? Also what are the best ways of sharing them once on the device? I'm not planning to shoot a full length movie or anything but I'm curious to know the limitations and how much memory these videos use. So you videographers out there help me out please and thank you.
