Black bars. You mean you want to achieve widescreen?
If so your camera must film in widescreen to begin with, if you don't have a widescreen camcorder (it will usually say: 16:9 or something along those lines) you will need to get a 4:3 letterboxer. I tend to use a green screen letterboxer, I know for a fact that Windows Movie Maker does not support green screen but your other program may. If this is the case, I have a 4:3 green screen letterboxer for you and it should be attached to this post.
