The easiest answer is perhaps the lack of commercial applications for desktop Linux, even for a popular distribution like Ubuntu. There is no shortage of quality desktop apps like LibreOffice, Firefox, GIMP and VLC – even Minecraft runs perfectly well with OpenJDK Java – but when it comes to multimedia creation, Linux desktop distributions still left behind. With no Photoshop, After Effects, Ableton Live, or Premiere Pro for Linux, we have to turn to alternatives. For image editing, GIMP and Inkscape have Linux pretty well covered, while Bitwig and Ardour meet most Linux audio editing needs. Thus, here follows my review of a few readily available Linux video editing software (I tested them on an up-to-date Ubuntu 18.04 LTS 64-bit system.) This list is not in order from best to worse or vice-verca. As I completed the test for one Linux video editing software, I wrote it down and ranked it based on my experiences.
Cinelerra *had* the most promise and it’s probably good if you want to run a TV station. However, it’s not creative at all. Simple edits are easy. However, anything else can become a stunt. IMO, Kdenlive has seen the quickest growth. Lives is also doing well. In the next few years we may see those apps grow into the free alternative of Finalcut – but not Cinelerra. It does what it does, and there is no need to change.
This video editing software offers customizable layout support, a clip list, a multi-track timeline, automatic backup, keyframe special effects, and transitions. Are you using any unique file format or camcorder? Not a problem — Kdenlive supports almost everything available. It should also be mentioned Kdenlive supports Mac OSX and FreeBSD as well. Another important feature is the Proxy editing. This cool feature can automatically create low-resolution copies of your source clips to allow light-weight editing, and then render using full resolution.
Do all this in a basic newly opened blender session. Then click save as default. Then when you open a new blend you will always have these presets select. If you do this mid work in some blend you are working that blend will become your default (almost never what you want to do). You might also want to skim through the addons. Blender has a lot of power that comes turned off by default but nothing much for film editor.
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

It has been a long known fact that there is a larger variety of software products for Windows and Macs compared to Linux. And even though Linux is continuously growing it is still hard to find some specific software. We know many of you like editing videos and that you often need to switch back to Windows in order to make some easy video editing tasks.
So, there you have it. After using these many video editing software on Linux, no doubt things are improving fastly. Now which video editing software you want to use depends on your specific type of videos you edit. If you just want to throw a small home video of your cat together, I suggest you use Pitivi, and if you really want to go at it, try Kdenlive. Either way, you should be just fine. But, to answer the real question, which is, “Which is the best video editing software for Linux?”, I would probably have to say Kdenlive, overall. Pitivi is great Linux video editor – really great – but Kdenlive is a little better. It has great features, and its stability is increasing with every release.
Cinelarra is for video producers who need more than OpenShot, and who want a native Linux professional-quality video editor that supports high-resolution audio and video, and advanced features such as hue and saturation, overlays, denoising, compression, normalization, time stretching, realtime effects, nested sequences, color balance, image flipping, text-to-movie, batch render and batch capture, compositing, and much more. Cinelarra has nice integration between audio and video, and makes it easy to control synchronization. Blender and Cinelarra work well together; create your splendid animations in Blender and then integrate them into a movie in Cinelarra.
The only criticism I might have for Kdenlive is that it looks like an open source program. It isn’t the most user-friendly application to work with and appears to have been programmed by someone who knows what they are doing but expects you to also know what they are doing. It isn’t the most polished experience, and some things seem to be a bit obtuse to do.
4.4 Indemnification: You agree to indemnify, defend and hold Noble Samurai and its affiliates harmless from and against any and all liability and costs, including reasonable legal fees incurred by such parties, in connection with or arising out of Your (a) violation or breach of any term of this Agreement or any applicable law or regulation, whether or not referenced in this Agreement, or (b) violation of any rights of any third party, or (c) use or misuse of the Noble Samurai Software.
Cinelarra has two versions: the unsupported community version and a commercial edition. Every six months the nice Cinelarra developers release the latest source code. It’s not widely available in the usual distro repositories, but the good Cinelerra-CV folks bundle it up into Arch, Debian, Fedora, Ubuntu, and other distro packages. There is a Cinelarra PPA— Personal Package Archive– for Ubuntu users. PPAs are user-supported repositories for specific applications, like Cinelarra. They’re not official repos, but they allow you to use your normal Ubuntu package manager to install and remove third-party software.
4.2 Copyright: You agree that you are solely responsible for ensuring that Your video created using the Vidnami software does not infringe any copyright or other applicable laws including but not limited to any images either uploaded directly by You into the Vidnami software or any images facilitated through the Vidnami software.
Pitivi could be described as the Linux alternative to Windows Movie Maker. Both video editors have a clear user interface that doesn’t present its users with a steep learning curve, and both are intended to help regular people express themselves through videomaking. Of course, Windows Movie Maker is no longer in development, whereas Pitivi is developed by a fantastic community of people who believe in open source software.
 Linux gets my pick as the best multi-media production platform because it is flexible, efficient, and secure. Your system resources are going to your work, rather than in supporting a bloaty operating system further bogged down by marginally-effective anti-malware software. In our previous installment we covered a range of excellent drawing and painting, photography, 3D rendering, and desktop publishing applications for Linux. And my favorite Linux distros for serious multi-media production.
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)

Far from the “it just works” dream, this program just does not work. I have a relatively fast i7 laptop with plenty of RAM, but OpenShot slowed my entire system to a crawl as soon as I started to edit some video. Firefox became unresponsive and OpenShot crashed or at least appeared to do so since a crash report window opened but OpenShot did not close.

I‘m looking for a free video editor similar to – Adobe Premiere Pro, Apple iMovie, Final Cut Pro or Microsoft Movie Maker under Linux Desktop operating system. My tasks are pretty simple such as cutting, filtering, and encoding tasks etc. Can you provide me a list of FOSS software which can be used for video capture and video editing purposes under Fedora or Ubuntu Linux desktop systems?

Cinelerra is the most advanced non-linear video editor and compositor for Linux. Cinelerra also includes a video compositing engine, allowing the user to perform common compositing operations such as keying and mattes. Cinelerra includes support for very high-fidelity audio and video: it processes audio using 64 bits of precision, and can work in both RGBA and YUVA color spaces, using floating-point and 16-bit integer representations, respectively. It is resolution and frame rate-independent, meaning that it can support video of any speed and size.
Gnome peep started this tendency of oversimplification. Some times you do want features. Some times you do want what you call “bloated”. ‘Less is more’ doesn’t mean less is actually more, it means “Do more with less”. It is annoying as hell when programs start to remove stuff that you actually use because they try to follow this blind tendency towards nihilism ad absurdum.

I've a few more things to add to this review, which I will over the next few days. I've published it now because "imperfect action is always preferable to perfect inaction" so, while the spiders get to work on this I'll have a break and fill you in with more stuff very soon. In the meantime, just got and get the 7 day free trial by clicking the BIG SPINNY orange button that I took ages to animate for you - it's a total no-brainer. If you don't like it, cancel - zero risk. If you do, you will thank me (but ONLY if you take action and start making some bloody videos, alright?)
