You can’t directly import H.265 files into iMovie for editing. To do that, you may have to transcode H.265 to iMovie more editing-friendly codec. Here is the simple how-to.
HEVC (High Efficiency Video Coding, sometimes called H.265) is not new video compression format or people, and is the successor of H.264. It could offers 50-75% more compression efficiency compared to H.264 video, while retaining the same visual quality. However, currently Apple has no plan to add support for H.265 codec. And that’s why many people’s attempts at importing H.265 videos to iMovie fail during processing. Fortunately, there is an easy way to fix the issue. You can get a H.265 encoder to convert H.265 to iMovie editing-friendly codec and then transfer the converted files to iMovie for further editing.
If you decide to decode H.265 to iMovie, a very handy HEVC decoder that you can use to quickly and reliably is necessary.
