There are many semi-professional video non-liner editing software in the market, most of them comes with a ridiculous price tag and or hardware requirement. Avid express DV is the king of this type of software. With only a quarter of the price and a not so state of the art computer, this software can give you pretty much the same professional look and feel if not more. On top of all these, it also comes with a DVD authoring software, you can easily create chapter, menu items and many other nice little thing.
The project file is so small, it is actually a reference file and it never really modify your original video files. Means even you deleted some segments of video or audio in your project, they are still in your original files. No need to worry that you accidentally deleted something and will never see them again. It also does not make a full copy of video for your project, so it will not chew up your hard drive space.
Adding text and background music is a breeze, works best when you creating a movie from home video. No matter you want to cut a piece and post it on You tube or burn a DVD for your grandparents, this is the best bang for the buck.
User menu and help document is not very helpful, but since the project will not change or hurt your original video, why not try everything yourself. Learning curve are really steep, once you learned the first few basic editing skills, you can add more new fancy looking effects to your project very fast.
