The top, and central, part of the Windows Movie Maker Timeline is the Video segment. This is the top section where you drag and drop specific video clips. Whenever you drop a video clip into there it will automatically position itself either at the beginning or the end of the previous clip, which is much different than most non-linear editing software. In this area you can alter clips, add video effects to specific clips, shorten or lengthen them, or even do specific tool edits.
