> recipient also has to have Dropbox to view
No. I recently shared a few largish movies to relatives via Dropbox. I put the .m4v movies to my Dropbox (4GB limit), ctrl-click copied the movie link and emailed just the link (or a link to the whole folder) with short instructions how to view or download it. The relatives could view the movie and even download the original movie without having a Dropbox account (Download > Direct Download).
For example, below is a 2 second short but large 43 MB Super 8 film sample clip from 1972 (it is a ProRes 422HQ unique frame Rank Cintel 4K scan at *25fps so it must be slowed down 72% in Final Cut Pro for approximately the correct speed and then exported as .m4v but you get the idea. *The service tried 18fps but we settled for 25fps because that was their normal workflow and that unique frame ProRes 422HQ is considered "raw" that can be post-processed to any frame rate):
