Introducing Lightworks, it’s a commercial video editing suite for Linux, Mac and Windows. It’s a non-linear tool with a completely different approach to editing video. Instead of a simple GTK or Qt window that is manipulated by the desktop environment (and themed by it too), the app offers up a full screen editing environment. Lightworks isn’t free. In fact, unlike the other apps on this list it actually requires a monthly subscription to use but it’s worth it if you want to edit and produce video on Linux.

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.
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.
Avidemux is a free, open source video editing software designed mainly for simple cutting, splitting, merging, filtering and encoding, etc. It is a cross-platform free video editing software and support various file formats with different codecs such as AVI, MPEG, MP4, ASF, etc. With it, you can easily edit your videos and output the edited videos for your iPhone, iPad, iPod, PSP, etc.
There’s often this misconception that there are not that many video editing software for Linux out there — however, this is not the case. With the growing popularity of Linux-based operating systems, software development companies have no choice but to focus on making software specially designed for Linux distros. Accordingly, you can find several video editors on the internet for almost any Linux distribution that you are using.
Just like VidCutter, it allows you to do basic editing tasks such as to trim, cut, snap, split, and mix your videos. For people who aren’t that well-versed in English, the software provides support for several other languages. Before using it, you should probably read its documentation, which comes with a lot of useful information on how to use this software.
OK, as what we use in our office, bearing in mind that we need to do rapid editing and splicing of 1080p video from two fixed point cameras, we use http://www.womble.com/ DVD Wizard. The cameras (yes two) get plugged in, the files are dropped on the time lines and within seconds we can start editing. Moving through the files, editing and splicing, is fluid and quick. Rendering the final product is, of course dependent on format as you’d expect but we tend to batch our work and let the jobs run overnight.

Nevertheless, when you find the elusive, easy to use video editing software that has the features I mention, that doesn't crash, or at least when it does crash recovers files the user was working on, that doesn't need constant tweaking using the shell, that has reasonable, non obfuscated documentation in understandable english, please let me know. I will buy you a beer and the software without hesitation.
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.
