I just finished working on a project on iMovie and have exported it onto my desktop. I want to put it on YouTube, but they only allow 15 minute videos. My video is 23 minutes long so I am thinking I just will split it in half and have a part 1 and 2 on YouTube. The file is a .M4V file, anyone know of any quick ways to just split it in half and make 2 separate files? Thanks!
