You might want to give up on the idea of using e-mail to send the video directly. What I suggest is that you upload the video to an online cloud storage. A lot of people here like Dropbox - and the first two GBs of storage are free.
Anyway - once you get the video to online storage, then you can send a link to it in an email. That way, your recipient can download it at her convenience.
that's one way I know to get around the e-mail size restrictions.
