If you have done any research at all into internet marketing, you have probably seen it written more than once that you should include video in your overall marketing strategy.  Online videos are very popular right now with the search engines, because they are very popular with the people who use the search engines (makes sense, right?).  SEO trends favor video marketing, so everything you've read advising you to add video to your marketing strategy is right. 

If you plan on using video marketing, then you will need to use video production software, or video editing software, to create a professional looking video.  But you may be wondering if it is expensive to do.  The good news is, it doesn't have to be.  For example, you may not know it, but you probably have some pretty decent video production software on your computer already, and its completely free.
