Upload movies over 15 mins

Greetings djenkins0119,

Sharing a movie to iCloud's iMovie Theater is indeed limited to movies less than 15 minutes in length. See this article -

It is possible, however, to share your movie to iTunes on your computer, where it can be played using either Home Sharing through your Apple TV. This article explains how to move the movie to iTunes -

Thanks for using Apple Support Communities.

Be well,

For that job I would burn a DVD using Apple's iDVD. With a single-sided DVD you can go 2 hours, a double-sided DVD, 3 hours, 45 minutes.

Blank DVDs cost about 15 cents.
