OpenShot is an open source video editor with a user interface that’s much simpler than most. That doesn’t mean it’s short of features, though. It has templates for creating titles, effects, the ability to remove the background from your video, and slow motion and time effects. You can also create 3D animated titles and effects, there’s support for unlimited tracks, and for more than 70 languages. The interface isn’t the slickest you’ll ever use, and there have been question marks over its reliability in the past, but it’s definitely worth trying if you want a free video editor for the Mac.
Though Shotcut isn’t the easiest software to just pick up and start editing videos with, the nature of being a free software means plenty of people are using it and making incredibly helpful tutorial videos or guides on how to use it. And, if you want a readily portable option, Shotcut is it, since you can run it directly off an external storage drive.
If iMovie isn’t for you, give DaVinci Resolve a try. It’s the free version of DaVinci Resolve Studio, but being free doesn’t mean there aren’t many features. It’s loaded with professional tools like some of the best color correction and image stabilization there is. In the free version, you can work at frame rates up to 60fps and export your movie in SD, HD and Ultra HD.
If you have a pressing need for a highly capable non-linear video editor, you should consider Adobe Premier as part of their Creative Cloud suite. You can rent it for $20/month (I believe) or the entire suite for $50/month. This is quite expensive, but if you have a job to do then you can't go wrong. Failing that, Apple's own Final Cut X is another mid-tier app that you can buy for a one-off fee (around $99 from memory).
Da Vinci Resolve, on the other hand, is surprisingly-feature rich. It offers multi-track editing and a huge number of professional-tier features to play with. Blender is open source and powerful, but is bogged down by complexity. Shotcut and Openshot are pretty evenly matched, so why not test drive them both? And if you’re looking for something specific to 4K video editing, check out VideoProc.
The really great news is that many of these programs are free. You might expect that free video editing software would have fewer features or produce less professional results than expensive software, but many of the free tools featured here are more than good enough to produce professional-looking movies. The only downside is that they tend to have a steep learning curve and they don’t walk you through the process of editing. However, there are plenty of video on YouTube to help you get started. Here are the best free and paid-for video editing applications for the Mac.
