I've tried a few of the freeware video editing programs that are available (try Googling "video editing freeware", no quotes). Most of them are OK for what they are but are nowhere close to the payware programs for ease of use, versatility, lack of crashes. Let's face it, anyone who creates a decent freeware program is going to package it to sell.
Getting some basic software is more of a problem if video is an afterthought (such as USB video) or you use all OEM parts for your pc. Buying OEM rather than retail graphics may actually cost you more in the long run because of the freebies.
When you buy a graphics cards (retail), it usually comes with some mid-range video editing software. That is usually the previous version, not the current one. With my ATi AIW card I got Ulead's VideoStudio 6. It's not bad for fairly simple compositions. I never upgraded. A decent range of effects, adjustments, transitions and output formats. Also basic dvd capability with menus. There are a number of similar apps like those from Roxio.
Windows Movie Maker is not a fave of mine. While downloading an update to answer a question in a forum, the download hung up and caused a crash of my pc that required reinstalling XP and all my progs! From what I remember the prog has very limited output formats.
If you are serious about video, then you need something of the calibre of Adobe Premiere Pro or Sony Vegas 60. Expect to pay more than the box price because of add-ons you may want. For mind-blowing shorts, Adobe After Effects and a selection of filters will relieve of your savings pronto.
