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.

Kino is a great program, but it only does standard definition video, and everything has to be converted to DV files (meaning you need a gigabyte for every 5 minutes of video, so editing an hour long video can easily take 12 gigabytes). Sound editing can also be a bit difficult, but one can always export the soundtrack, edit in Audacity, then dub it back in (and I’ve done this for a couple of videos I’ve made). It’s still my favorite video editing program in spite of these limitations, for now.
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.

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.
Pitivi is a Non linear video editor and also open source software that freely available. For intuitive video editing this software is designed. It supports simple features i.e. snapping, trimming, splitting, and clips cutting. Pitivi curves system supports audio mixing feature. It has the ability to use the keyboard shortcuts and scrubbers.

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.
You can develop your very own motifs. You can add your very own logo designs and brand name watermarks, consist of great background pictures as well as different textures along with individualizing the font styles and colors quickly (just a few clicks of the computer mouse) to make extra professional-looking video clips as well as match your company’s/ site’s design and also look.
