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.
Audio and video clips can be linked together and managed as single clip. Another thing that I personally find useful is that Pitivi can be used in different languages and has a very extended documentation. Learning how to use this software is easy and doesn’t require much time. Once you get used to it, you will be able to edit video and audio files with high precision.

A non-linear editing system (NLE) is a video editing (NLVE) or audio editing (NLAE) system which can provide editing method for video clips or frams. You will be able to access any frame in a video clip. Non-linear editing is done for film and television post-production. However, the cost of editing system gone down and non-linear editing tools (including software) are now within the reach of most home users.

Whether you’re cutting a feature or just editing a short or two or even a youtube video, having an NLE that you don’t have to wonder about (whether it’s going to just slowly fall apart) is preferable. What is the basic stuff most people use? I’m a rather accomplished editor and I find that even for the simplest projects I tend to use advanced techniques. However, that doesn’t stop me hoping that someday someone is going to create an NLE for Linux (commercial or not) so that I can make the switch full time. Because I love the command line and I love the free part, and I like being part of the friendly community…the more time I can spend hacking wifi the better.
This Linux video editing software is an interesting one. Kino is not your typical iMovie-style non-linear video editor. It appears to have been created in order to primarily cut a single video, or maybe a couple of videos to make a home video. It works pretty well but it requires one to use only standard NTSC or PAL formats with their respective framerates and video sizes. All in all, the video editor is stable and easy to use, but very limited.

It supports high-definition video, Blu-Ray, 3D, tethered shooting, integration of video, audio, and still images, all the usual effects such as scrolling titles, pans, and fades, animations, speed changes, audio mixing, export to multiple formats and quality levels including YouTube and Vimeo, and tons more. It is under active development and has great community support. This may be the only video program you’ll ever need.
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.
That was the first video editing software package I bought for making home movies. It was easy to use, intuitive even, although some bits were a bit clunky. After making 20 or so coasters, it turned out to be near impossible to burn DVDs. Going online I discovered that burning DVDs was a common problem that upgrading wouldn’t help so I bought Vegas. Since my goal is primarily making home movies for distribution to a far flung computer illiterate family (and that isn’t even just the octegenarians) this is important.

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.
The option to group multiple video and/or audio tracks is absolutely marvelous for use with multiple view angles and sound tracks. This permits you to modify all the tracks at the same time and prevents the need to constantly re-synchronize your clips. KDENlive can also edit multiple selected tracks at once without grouping them, which permits great flexibility when changing edits. See More
I've a few more things to add to this review, which I will over the next few days. I've published it now because "imperfect action is always preferable to perfect inaction" so, while the spiders get to work on this I'll have a break and fill you in with more stuff very soon. In the meantime, just got and get the 7 day free trial by clicking the BIG SPINNY orange button that I took ages to animate for you - it's a total no-brainer. If you don't like it, cancel - zero risk. If you do, you will thank me (but ONLY if you take action and start making some bloody videos, alright?)
