HEVC, also known as H.265, is a new codec that has been growing in popularity since it's recent unveil. It has proven to be faster and much more efficient than H.264 and in a few years there's a good chance we're all going to be using it. However, there is no support for HEVC/H.265 from Apple currently. That's the reason why you cannot import and edit H.265 files in iMovie, Final Cut Pro, etc. But that doesn't mean you cannot use H.265 codec in iMovie. To achieve this goal, what you need is just a H.265 encoder that can convert H.265 to iMovie compatible file formats.
