YouTube toolbox is a great resource for video filming and editing techniques. This specific link offers some tips to make the video stand out. http://www.youtube.com/t/studio_article_15

I’m working on my own video oriented blog but I haven’t got too far yet. I like the youtube link you supplied. Good luck.
