Final Cut Pro is easier to use than some other video editors, but it's powerful enough for professionals to use regularly. Final Cut Pro X is a step up in almost every respect. If iMovie doesn't seem to be enough for you, Apple has another option. iMovie also handles 4K footage, you don't have to worry about whether high resolution is supported or not. So you can edit the video on your iPhone / iPad and finish it on your Mac. This is a great option if you record videos on your iPhone, which is also available for iOS. You can't build a feature film project using this software, but if you just want to put a quick video on YouTube, iMovie will do it for you. The software is free for beginners, but it also combines ease of use with a fairly advanced feature set. If you are new to video editing, one of the best editors to start with is Apple iMovie.
