of course these software are non-free.you should pay some money to use it. if you do not care the quality of the vedio that you edited,you can try some free softwares. for example:

1. Windows Movie Maker 2
Windows MovieMaker 2 is a capable little editor and ships free with virtually all new XP computers these days, with upgrades available on the Microsoft Website and other addons available as part of the Plus! package.
2. Apple iMovie'05
Apple iMovie '05 is an excellent (and free) video editor for the Mac platform, with advanced video editing features and a lot of addon and plug-in support. You can find more information about iMovie at Apple's iLife '05 site. Note that this software is free only if you buy a new Mac. You can purchase it, however, if you just want the software.
3. ddclip Free
DDClip Free is another homegrown video editor, this one from SoftLab-NSK, a multimedia company headquartered (apparently) in Russia. Its interface is a bit difficult and this product is really aimed at the geeks among us, but it's free and that's the best thing about it. SL openly admits that this version is no longer supported and they'd like you to go with one of their "retail" versions. I didn't download or test this product, so I can't really comment. Again, let the buyer beware, and so on.
4.Avid FreeDV
Avid's free software lets you get in the Avid door for free. Fairly difficult to use interface, although over a dozen pretty good tutorials are available from Avid's website. Originally developed for Windows XP, FreeDV now runs on Macs on the OS X platform.

One or two editing tools is not enough for you to make your editing job perfect, so try to use different editors. Good luck everyone!!
