Not knowing what you need it to do, it is hard to comment but it is very easy to use just for movies. You just open up the track you need and position it on the timeline thingy. You then put the next track on the next line. You can then add blends or whatever you want and you can edit each track right there in the viewer. When you are done just render it out. It is true that this bit of blender is just a small bit in a very big program but if you focus on just this little bit you can learn it in a few minutes.
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.
After experiencing various crashes (on Ubuntu 9.04) with Avidemux, LiVES, and Kino, I switched to Cinelerracv. I had avoided switching becasue it was a bit intimidating at first. Then I discovered the tutorials atAkirad, and with some effort, have mastered its capabilities. Combined with FFMPEG (and a neat little GUIfor it called WinFF) and Audacity for specialized audio work, I have a suite that can do whatever I want and produce it in whatever format I desire. Thanks for the reviews. They provide a great path for investigation…
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?
The trade off is often money fortime, and the market reflects that. Tools aimed at “pros” tend to be expensive because they are based upon the money saved by their market. Few amatuers or casual users will fork out thousands of dollars for software in order to save a bit of time–even if it would be cost-effective for them, since many people never bother to do cost-benefit analysis.

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.

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.
