Open Shot is a video editor for Linux operating system written Python. It is open source video editing software and also freely available. It main features to support many audio, video and image formats. Better drag and drop feature. In open shot cutting, trimming, snapping and cropping are easier. It also supports video transition, compositing, 3d effects and motion picture credits. Open shot is user friendly software that gives also support of animation of key frame, easier encoding of video, digital zooming, editing and mixing of audio and digital video effects. This video editor software provides compositing and mainly extensive editing tool for practical working on high-definition video with HDV and AVCHD.
Davinci Resove is another non open source video editor for linux, like Lightworks. It used to be a very excellent color grading software, and now, it's a great video editor as well. You can do all the basic editing and some of the advanced editing on the free version (multi-camera editing, 3D editing, motion blur effects, and spatial noise reduction, etc are only available on the paid version)
Shotcut is anther video editing software for Linux and it is an interesting one because its UI looks more like a media player than an editor. The software makes editing video very simple with the set of awesome features it has. For basic uses, it will work just fine, but if you need more powerful options, especially for advanced or professional video recording, then it may not be the best. However, with the features it has, it qualifies as a decent video editor for Linux.
The most promising or also often called best Linux free video editor of all, OpenShot has a long history of development and should be mature and stable. I downloaded the latest Openshot from its PPA since the one in the main Ubuntu repositories is, rather perplexingly, a very old and outdated version. Once OpenShot is opened, it appears very easy to use. The default layout is simple and intuitive, and there are even hints that pop up the first time you use it! I drag-and-dropped a few videos I had taken in preparation for this post, and boy, was I disappointed with this so-called best Linux video editing software.
