Video Editors to consider...

Finding the right Video editor could be a challenge too. There are many with varying features.

Windows Movie Maker - The best video editing tool for Windows that's absolutely free and chances are you already have it installed on your computer as part of XP SP2. Microsoft Movie Maker has all the basic video editing tools plus a good collection of transitions and video effects.

Avid Free DV, poor cousin of Avid Xpress Pro, has all the basic video and audio editing features and allow you to put video in two tracks simultaneously. They have an extensive collection of tutorials online to help you get started quickly.

While all the above free video editing software will satisfy the needs of most amateurs and home movie makers, you can consider Adobe Premiere Elements, Pinnacle Studio, Ulead Studio, Sony Vegas, Nero or Muvee Auto Producer for more features and better control over the final video output.
They have trial versions to help you try out the software before actually buying it.

I will try to make references to the techniques used to produce some of the effects on my site.
