Lightworks is a feature-packed video editor with a truly impressive resume. It was used on movies such as The Wolf of Wall Street, LA Confidential, and Pulp Fiction, and there’s nothing stopping you from seeing first-hand why so many professionals like it because you can download it for free and use for 7 days without paying. If you decide that Lightworks is worth your money, you can upgrade to Lightworks Pro and unlock additional features.

I use Blender 3d for most of my video editing. You can do things with it that you would not beleave! Problem is that Blender3d is its own world and learning it takes time. It is something for a pro with some 3d modeling skills or a normal person that can read and is willing to learn the GUI. Wait for Blender 3D 2.5 to come out. It has an all new interface and new improved work flows! Should be out in a month or two…
Blender 2.8 makes video editing a LOT easier (start UI, easy to drag file, left click select...). It's still a bit harder to learn than other tools but for power users each shortcut you'll learn can be applied almost everywhere (e.g. pressing "i" on a numeric field to keyframe the value, or "g" to grab and move and element...). It's very powerful especially if you want to also include 3D in your videos. However many standard tasks will take more time in Blender: The preview is slow, to do a high quality zoom in animation you may need to use a Compositor or instead crop, rendering in 10 bits requires a lot of temporary disk storage, video stabilization is also a pain... Overall I'd suggest it more for someone interested in 3D doing also video editing. See More

People who dislike Linux usually say that it’s not great for professional, high quality video production and as a result the industry ignores it and doesn’t take it seriously. This isn’t entirely true.  It is very much a fact that Apple Computer will never release Final Cut Pro for Ubuntu, and Adobe will never make a FlatPak version of Premiere, but it doesn’t matter. Some commercial, professional video editing tools do find their way onto Linux.
Coming from a film editing background I *know* how to edit, it’s just the tools I need to master. It should not be that hard. What’s finally pushed me over the edge is that the windows codec is broken (I have the worst lemon version of XP you can imagine) so that I can’t even see the images for the thousands of hours of video I have recorded with my Canon camera in the premium video editing software available for Windows But I can’t replace the codec because Windows thinks it works, so it won’t reinstall. Which is too bad because I slaved to learn that bloody commercial editing software that cost a bomb and got quite good at it. But intuitive? No way, Pierre.
Ya know, I have to chime in here. I am using Ubuntu. I love it but what I don’t love is the attitude of some of the Ubuntu techies. I am not a programmer but I am far from computer illiterate, in fact, over the weekend I was in the company of a computer programmer who complimented me on my knowledge…self-taught at that. I like the challenge of Ubuntu but sometimes you just need a question answered that will help you move on to your next phase of research. I sometimes spend weeks…WEEKS, researching a problem before I ask a question. And that is not a complaint…I like doing the research. What I don’t like are the snotty responses you sometimes get from the techies…almost as bad as Mac lovers. So I have learned not to bother with the Ubuntu support sites so much and just do general research on the ‘net , like YouTube (where I have found many of my answers, thank you). On the one hand…it’s too bad some of the attitudes are so cheeky. On the other hand, I learn a lot.
Trey has a good point, I don’t want to do much more than combine my video with a few transitions and a soundtrack. Kdenlive works fine for that. My biggest issue with Linux video editing is the lack of good transitions and simple drag and drop functionality. Also DVD menu creation is still really poor on Linux. But over the last four years it has gotten much better.
Blender is a fabulously sophisticated 3D computer graphics and animation creator. Check out the Blender gallery for a sampling of movies created with Blender. It supports a large range of high-end abilities such as ray-tracing, key-frame animation tools, object tracking, super nice character modeling, realistic physics for great liquid and smoke/mist/gas effects, and realistic movements of objects and characters, and excellent realistic light effects.

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.
You can develop your very own motifs.
