Personally, I would suggest a NAS with a VPN connection as you would a) need a alot of cloud storage b)a reliable internet connection would a very high upload speed for video (That's not even getting into the security issues associated with FTP).
You can check out Microsoft flow if you don't want to use third party solutions as there aren't any specific FTP settings for onedrive (on the consumer side) you can use without third party solutions such as Filezilla Pro.
