I was wondering what the smallest video format is, or if they are all the same. Cuz i have an Ipad and want to put a couple of movies and there, but want to save space. Thanks in advance!
X264 (mini-mkv) is the smallest for good quality. I always try to use it. You can find it mostly on anime sites, but there are converters for it too. Just search for an x264 converter and you'll get one.
