I’ve twiddled around with a few of the programs mentioned here but they all seem horrifically counter-intuitive. That is to say, I could not figure them out. (and I have the strong motivation of a soccer team clamoring for their annual ‘best of’ movie.) Windows might be f#2%ed, but Apple is downright frightening these days. Free is more and more the only way to go.

Like you, I’ve never been able to keep Cinelerra open for more than 10 minutes but in my case, the reason wasn’t the ugly UI. The problem is rather that it is a total crashfest! I do not know a single piece of software under Linux that exhibits that many lockups, race conditions, segfaults etc etc. Heck, on my system, it can’t even load a project that it saved 2 minutes earlier without crashing and that sadly ruins the featurewise winner of the competition completely.
Crash, crash, crash... when it didn't crash I found it to be in that middle zone of more than a basic editor, but not a professional one... features are not very intuitive. It took me more than 30 minutes of randomly clicking to figure out how to adjust the effects applied to a clip and then I was underwhelmed with the options. To be fair... I was looking for something specific when I tried this out. I've used Adobe and other video editors in the past and this just missed my current needs and my expectations based on past experiences.

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.
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.

Even though Olive is in the early stages of development (version 0.1.0 Alpha at the time of writing this article), some users are already using it to produce content on a regular basis, and its developers are making rapid progress, which is evident from their activity on GitHub. Hopefully, they’ll be able to keep up the current pace and give all Linux users the video editor they deserve.
Pierre, did you not see the mention of Blender??? It is GREAT for doing video. Yes, you do have to learn it but you want to do a good job right?? One thing to note. It is best in blender to turn the movie into a series of stills in the openEXR format. It is also important to go into settings and increase the buffer memory so that you get a much faster response as it loads much more movie at one time. Make sure to render the firm into its own director or you will have a LOT of picture files cluttering some other directory! Also more Ram mean better responsiveness and having a SSD drive is also a GREAT benefit. I would think this is true of any system.
LiVES is supposed to be mature, feature-rich and ready for more professional use-cases and even video jockeying. Both the website and the Wikipedia pages seem promising. However, although I was able to install and open it just fine, it refused to resize properly and did not import a single video. (If there is a “proper” way to import video’s, apart from the way the program makes it possible for users, then I was unable to find it.)

It has got a tremendous range of tools and techniques to provide the best experience of audio video editing. There are 2 move and 3 trim tools alongwith 4 techniques of appending, overwriting and inserting a clip on the timeline. Another great feature of this video editor is that if has more than 50 image filters and more than 30 audio filters to ensure the best video and audio editing output.

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.
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.
The option to group multiple video and/or audio tracks is absolutely marvelous for use with multiple view angles and sound tracks. This permits you to modify all the tracks at the same time and prevents the need to constantly re-synchronize your clips. KDENlive can also edit multiple selected tracks at once without grouping them, which permits great flexibility when changing edits. See More
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.
I wanted to use a Linux first, open source editor but I rely on stability for work and sadly I couldn't get a workflow that didn't include a significant number of crashes and glitches. DaVinci Resolve on the other hand is absolutely stable, never crashes, never glitches, has excellent tools, a smooth workflow and incredibly fast rendering. IMO better than Premiere. See More
A non-linear editing system (NLE) is a video editing (NLVE) or audio editing (NLAE) system which can provide editing method for video clips or frams. You will be able to access any frame in a video clip. Non-linear editing is done for film and television post-production. However, the cost of editing system gone down and non-linear editing tools (including software) are now within the reach of most home users.
After briefly testing all the various open-source video editors I could find easily available for fedora 13, I came to the conclusion that kdenlive was the best fit. By and large most of the editors were plain unusable for more than 5 minutes or just had too many limitations. kdenlive has its own faults, including that its documentation is not always clear and one must refer to it constantly when figuring out the UI (hint: video tutorials were so useful to understanding the docs). Essentially, I can now do almost anything I need to with kdenlive now, but I would greatly appreciate it if the devs could improve rendering time, update the dvd creation wizard to support blu-ray, and add more rendering options (for example, ogv output does not support quality levels, only bitrates). As for stability, I saw several crashes when I was first exploring features, but none since.
Pitivi is a Non linear video editor and also open source software that freely available. For intuitive video editing this software is designed. It supports simple features i.e. snapping, trimming, splitting, and clips cutting. Pitivi curves system supports audio mixing feature. It has the ability to use the keyboard shortcuts and scrubbers. In this video and audio can be linked together and this is a great advantage of it. It is the first open source video editor that support the MEF- material exchange format. Pritivi's user friendly interface gives drag and drop, direct manipulation, reducing complexity and native theme navigation. This software can be translated into several languages. It has also a user manual support.
