iMovie is my favourite video editor to I recommend to beginners. It’s a shame that the software is exclusive to macOS and hence neither Windows nor Linux user can enjoy this editor. However, If you do own a Mac, you must know that iMovie comes pre-installed with your Mac which essentially makes it free. But that’s not what makes it best for beginners. The best part about iMovie is its simple and intuitive interface which is really easy to figure out, even without help. Also, Apple’s optimisation makes iMovie a really snappy editor which can be used even on older Macs without any problem. As a beginner, iMovie is the best video editor you can use on a Mac. I say this especially because iMovie acts as a really good primer for Final Cut Pro, which you are essentially going to use as you get more and more comfortable with video editing and iMovie no longer satisfies your requirements.
If you had access to the video editing pro level, then you must try DaVinci Resolve 14. Except for multi-camera editing, 3D editing, motion blur effects, and spatial noise reduction which are only available on the paid version DaVinci Resolve Studio, you can almost do any professional video/audio editing and color correction with DaVinci Resolve 14.
iMovie is one of the easiest video editing programs out there. With a couple of clicks and some dropping and dragging you can conduct high-quality edits that seriously enhance the quality of your video. And with One Step effects you can apply a variety of different editing techniques instantaneously to your whole video, with just one click. The audio editing capabilities are also a program highlight, with 19 different unique audio filters that allow you to easily edit sounds and even change voices. iMovie is considered a consumer-level editing tool, so it’s not at all hard to learn.
