for starters, you can explore Windows movie maker, it's just part of windows xp package.

and as you go along, suggest nako nga professional video editing software kay Adobe Premiere (simple ra man kaayo)... Sony Vegas (k ra pod). If you're using Mac then , better ang Final Cut..

If ever duna na u nahimo video, sulay ug post sa youtube.com, for some of your experiments, you might like to make your own personalize MTV, your family picture himo-on nimo video, you will enjoy it.
Duna pod freeware software DdClip, saun ra kaayo, though of course limited lang ang feature sa freeware version.
As you'll learn video editing with good foundation, most of the video editing software pare-pareha ra man. Dali ra man kat-on.
