I am unable to email videos due to size ( even 15 seconds) Any help appreciated.
A common option would be to upload them to a video sharing website like YouTube.com. And if desired, videos can be marked as private there so only those people with the link will be able to find them.
I save them in Dropbox and share the link. You can use Google Cloud or MS One Drive etc. As previously mentioned posting some on YouTube will be a future option for me, and you can tag them as private so only those you send the link to can view them.
A point of clarification: Unlisted on YT means anyone with the link can view them. Private means the viewers also have to have their own YT account to view them, also with the link.
