ReAspect

ReAspect is a stand-alone application to adjust settings of an image. You can crop the 4:3 images or you can stretch the image in your image manipulation program. DVD-lab and DVD-lab PRO has strong integrated menu designer with multiple undo or redo. DVD-lab PRO adds also new DynamicFX textures that can be animated for Motion menus. With ReAspect you can gradually stretch (or pull) only certain part of the image while keeping the important part intact.
