The other way to share it is if it isn't over 5gb in file size you can sign up for a box.com account and upload it to there and then send a link to it to someone.
I was able to copy the video from my phone to my sisters computer, but it was still to large to email. Anyway, when it was on there it said it was 3200 something in size. I don't know if it was mega bytes, kilo bytes, giga or what byte is bigger then which other one, but my sister said that was a huge file. When I tried to email it, it said that it can only send files that are 100 something in size.
