… the idea is NOT to share movies(edited projects from Imovie) but to share files from the camera, …
so copy the whole structure into a folder, share it via DropBox, GoogleDrive etc.
others can use their editors, players etc to watch&process the 'raws'.
.... but we talk of Gigs of bytes! = looong upload times.
my son's coach gets my un-edited recordings as single mov for his iPad on a usb-flashmem-stick, a day after the game.
I'm using the Turbo.264HD.app and Elgato's Turbo-stick, which allows to drag the raw mts into it; the app re-wraps and combines the diff. files.
The idea there is to send a movie file in a format that is easily edited. You would not have to edit it; Personallyl I use an Elgato TurboH264HD to make .mp4 files. I'm sharing about 40 movies with family for Christmas. They will be on DVD, Flash sticks, and my web site.
