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.

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.)

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.
Using Linux does not mean that you can’t have high-quality software on your system. Apart from the video mentioned above editors, there are tons of other software available in the market for Linux. Some of them are aimed at professionals (just like Lightworks, DaVinci Resolve, and Blender), while others cater to the requirements of beginners (similar to Shotcut and VidCutter). Moreover, you will also be able to easily download and install video editors on your Linux system, as most of them are already available on the app store.
Last 5 years of my 7 years Linux experience I was regularly challenged by day-to-day video editing tasks. Main content was 720p/1080i/1080p in ts/m2ts/mp4/mov. The most useful instruments that produced a really nice results was combination of avidemux, kdenlive and VirtualDub (under Wine). As per my experience you are able to get excellent results with those tools but the problem is workflow really uncertain and not stable sometimes. Lack of features also has place. But the situation changes. Right now Kdenlive project is really nice. It has tons of features and stable enough for relatively serious editing/finishing. I am sure this won’t be too hard for any person interested to learn Kdenlive workflow. Otherwise this person is too lazy for Linux in general. You may find plenty of video lessons on ytube/vimeo.
