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.
Look at the screenshot I attached above. I want you to look at the left sidebar. The #01 “Getting Started” video is what I just walked you through. You can see there are more video instructions. The videos are between 2 and 5 minutes long each, so it doesn’t take long at all to become acquainted with the software. The 5 additional training videos include the following topics.
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.

I usually edit short videos from my life like play with kids, travel and bike rides, and sometimes do software project demos and tutorials. I tried all major tools in linux for video editing. Blender seems to be the most feature rich and consistent. It allows me to handle 4k video on my oldish laptop. It always feels so good that I buy its future for 20-50 bucks time to time. See More
Kdenlive is an intuitive and powerful multi-track video editor, including most recent video technologies. Kdenlive supports all of the formats supported by FFmpeg (such as QuickTime, AVI, WMV, MPEG, and Flash Video), and also supports 4:3 and 16:9 aspect ratios for both PAL, NTSC and various HD standards, including HDV. Video can also be exported to DV devices, or written to a DVD with chapters and a simple menu. Kdenlive packages are freely available for GNU/Linux, FreeBSD and Mac OS X under the terms of GNU General Public License version 2 or any version later.
 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.
It supports high-definition video, Blu-Ray, 3D, tethered shooting, integration of video, audio, and still images, all the usual effects such as scrolling titles, pans, and fades, animations, speed changes, audio mixing, export to multiple formats and quality levels including YouTube and Vimeo, and tons more. It is under active development and has great community support. This may be the only video program you’ll ever need.
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.
Audio and video clips can be linked together and managed as single clip. Another thing that I personally find useful is that Pitivi can be used in different languages and has a very extended documentation. Learning how to use this software is easy and doesn’t require much time. Once you get used to it, you will be able to edit video and audio files with high precision.
Right now there is one really serious competitor coming out with it’s brand new open source non linear video editing product. I am talking about Lightworks` Oscar winnig Editshare which has been released open source last year. Feel free to discover their website http://www.lightworksbeta.com/ and tons of professional features it has. Yes this is not intended for video editing noobies but this is going to become a really brilliant piece of software for Lin/Mac/Win. Right now only Win version is accessible but:

Kino is a great program, but it only does standard definition video, and everything has to be converted to DV files (meaning you need a gigabyte for every 5 minutes of video, so editing an hour long video can easily take 12 gigabytes). Sound editing can also be a bit difficult, but one can always export the soundtrack, edit in Audacity, then dub it back in (and I’ve done this for a couple of videos I’ve made). It’s still my favorite video editing program in spite of these limitations, for now.
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.
Content Samurai promises that you can “Create Stunning Videos Fast” with their app. You can use Content Samurai video creation software to turn articles, blog posts and shorter pieces of content into videos in minutes, or so the creators claim. I’ve spent a lot of money having freelancers create videos for me, so I figured I would give Content Samurai a shot.
