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.

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.

An excellent guide and resources for anyone trying to start editing, and publishing videos. I have used few of these to achieve my video. I use Kino to capture, sometimes Kdenlive to slice( No I know how to do it in cinelerra), and finaly use the cinelerra for the rest of the editing, up to encoding. if they asked me what I wish for for my birthday, I would wish for the Kdenlive to be as powerfull as cinelerra, as it is so logical and easy to use. To me most are buggy, but at the end I managed to edit, and put my composition on Youtube. Check it out. ItÅ› all been done with Linux.
Feature wise, Cinelerra looks to be the best fit if you want to do anything serious, and that’s a problem, because it falls apart when doing anything serious thanks to a seriously bug ridden code base. I mean it! This thing is such a race-condition fest, it can’t even open its own project files on my system without crashing! (Start project, add clip, save it, try to load it … freeze!)
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.
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.
