I wanted to use a Linux first, open source editor but I rely on stability for work and sadly I couldn't get a workflow that didn't include a significant number of crashes and glitches. DaVinci Resolve on the other hand is absolutely stable, never crashes, never glitches, has excellent tools, a smooth workflow and incredibly fast rendering. IMO better than Premiere. See More
I’ve had good luck with Lives. I’ve been able to accomplish things with it that I couldn’t figure out how to do with the others. My main use of video is for web sites. I’ve even created a video sequence from a JPEG still which I then manipulated with Lives tools and output as an animated GIF. I further tune the size of the animation in GIMP which allowed me adjust the the frame rate on a per frame basis.

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:

After briefly testing all the various open-source video editors I could find easily available for fedora 13, I came to the conclusion that kdenlive was the best fit. By and large most of the editors were plain unusable for more than 5 minutes or just had too many limitations. kdenlive has its own faults, including that its documentation is not always clear and one must refer to it constantly when figuring out the UI (hint: video tutorials were so useful to understanding the docs). Essentially, I can now do almost anything I need to with kdenlive now, but I would greatly appreciate it if the devs could improve rendering time, update the dvd creation wizard to support blu-ray, and add more rendering options (for example, ogv output does not support quality levels, only bitrates). As for stability, I saw several crashes when I was first exploring features, but none since.
people people just remember that these programs are free and give u an idea and also experience on how to use them without paying, i myself have been a pc user for many year and apple has caught my eye. if i get what i want i`ll be using apple for final cut pro editing and filming but also will be running ubuntu on a dual boot for my other programs. the free programs will help me to understand how the editing process works and final cut will make me better. the best of both worlds! Cheers

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.

OpenShot is a cross platform video editor that is “simple and powerful”. It’s built specifically for the YouTube generation or, anyone looking to make simple videos by cutting things together and adding a few effects here and there. By no means is it on the same level as something like Final Cut, or Premiere, or even Kdenlive. Instead, think of OpenShot like Linux’s iMovie.
Blender is a fabulously sophisticated 3D computer graphics and animation creator. Check out the Blender gallery for a sampling of movies created with Blender. It supports a large range of high-end abilities such as ray-tracing, key-frame animation tools, object tracking, super nice character modeling, realistic physics for great liquid and smoke/mist/gas effects, and realistic movements of objects and characters, and excellent realistic light effects.

Davinci Resove is another non open source video editor for linux, like Lightworks. It used to be a very excellent color grading software, and now, it's a great video editor as well. You can do all the basic editing and some of the advanced editing on the free version (multi-camera editing, 3D editing, motion blur effects, and spatial noise reduction, etc are only available on the paid version)
The point is, I make some of my income from editing video files. They are an important part of our business’s value adding strategies. So I don’t have time to experiment. I need something that works and is easy for our staff to master. Windows and Mac software does and, like most businesses, we’re happy to pay the price so that we can get on with the job. BTW, the package we’re using costs less than $100.00 per seat, has easy to understand configuration and user settings, is easy to master, makes editing, cutting, dubbing a doddle. It also batches files for rendering (from the GUI). it is reliable and robust, comes with excellent support and the authors have been quick to respond to requests for new features. It is also written to actually run in a multitasking environment so we can do other things when video files are being rendered. Linux authors, take note.
Thankfully, you can get Vidnami at a 25% discount off its normal price. (This link will send you directly to the checkout page.) So, instead of its retail price of $47, you’ll only pay $35, saving you $12 a month forever (again, for as long as you keep your monthly subscription after clicking on the previous link and taking advantage of this discount deal).
