There's also a commercial product, Lightworks with a free beta available to use, if you register. There's a SlackBuild here.

Caveat: haven't tried it personally, it's on my todo list.

Although there's a "beta" available, lightworks is available all platforms, whether free, or for payment. Registration is not requires (I checked :) ) The "free" version is limited in some functionality. The Version comparison is here: http://www.lwks.com/index.php?option...102&Itemid=213

Some of you youngsters may not remember that this was a popular software distribution method in the last Century, ofter referred to as "shareware" or similar moniker.

Avidemux
 

Can't believe no one recommended avidemux.
Used it for years.

Avidemux is an excellent program, but doesn't really qualify as an editor - other than at the most basic level of "cuts only". I often use it for removing the commercial breaks from off-air recordings, as it allows me to strip them out without re-coding, thus preserving quality and being really fast. However, a good editor will allow for much more sophisticated joins, including (but not limited to) mixes, wipes, cutting sound and vision in different places, titling, sub-titling, DVE, etc, etc - all things beyond Avidemux's capabilities.

However, Avidemux does make an excellent transcoding tool to prepare video for editing in less capable editors.
