Maximum Incoming E-mail Size?

I believe the max e-mail size, sent or received, is 20MB, that includes text and all attachments.  I would suggest using a cloud service, like dropbox, to share videos.

Even though the official amount is 20MB, after binary conversion, its more like 14MB as per this.

+1 For dropbox, or even setting up a private youtube account, assuming its home movie type stuff.
