iMovie won't upload to iCloud

I've got a couple of movies that won't upload to iCloud. They're both over 15 minutes long. Are there restrictions on uploading to iCloud from iMovie Theater?

So it will go to my other computers and laptops and iPad and iPhone automagically!

I am guessing it's too big? Why do you want it on iCloud?

Try using Vimeo or YouTube?
