can i share imovie theater clips that are too big for icloud?

I have transferred my old vhs tapes to .mov, edited them in iMovie, and added them to iMovie Theater (most of which are over 15mins so I know they can't be shared via icloud) and wish to gift these larger non icloud clips to my kids so they can add them to their own mac pro's. One child is in at home so I have access to his laptop, the other lives overseas with his mac pro.

Can this be done, and how?
