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.
Lightworks is a feature-packed video editor with a truly impressive resume. It was used on movies such as The Wolf of Wall Street, LA Confidential, and Pulp Fiction, and there’s nothing stopping you from seeing first-hand why so many professionals like it because you can download it for free and use for 7 days without paying. If you decide that Lightworks is worth your money, you can upgrade to Lightworks Pro and unlock additional features.
I have worked with several commercial offerings including Final Cut Pro, Premiere and Video Wave. I recently used Cinelera (on Ubuntu Hardy) on several projects and I like it very much. Cinelera is much more powerful than Video Wave and is more near the class of Final Cut Pro and Premiere.

To be fair, I have seen similar stability issues with the commercial products as well so I do not find this aspect of Cinelera any different.

Shotcut is anther video editing software for Linux and it is an interesting one because its UI looks more like a media player than an editor. The software makes editing video very simple with the set of awesome features it has. For basic uses, it will work just fine, but if you need more powerful options, especially for advanced or professional video recording, then it may not be the best. However, with the features it has, it qualifies as a decent video editor for Linux.
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:
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.
