When I click File > Share > YouTube (username) a box pops up, but the "next" button is not highlighted and is not clickable. I've also tried to upload the files from the YouYube website but when I do I get this error and a 0% upload:

"We did not recognize the format of this file, but we will try to process it anyway. See this article on recommended formats for more information."

The file extension is .imovieevent.

What can I do to successfully upload to YouTube?

    You seem to have 2 distinct issues - 1)If you can't persuade it to share directly to YouTube, then export as 'Apple' instead & upload manually. Check iMovie is correctly logged into your YouTube account [awkward if you have more than one account or even feed/stream] 2) .imovieevent isn't a movie in that sense - it's iMovie's list of what clips are in the movie, crossfades etc. It's only a few KB in size & is only of any use to iMovie itself.

  • File menu > Share > File… btw, the reason you don't have a 'Next' button could be that you didn't sign into YouTube in iMovie first - it's interactive, no sign in, no upload.

I don't have much experience with iMovie, but I would suggest exporting your video, then uploading it to YouTube. In the past I have used inbuilt uploading mechanics and they don't tend to be the most reliable of things.
