It features remastered high definition picture, sound, and special effects as well as a re-recorded voice track by most of the original cast.  As most of the series' sketches and animation cels had been discarded since the final episode of "Dragon Ball Z" in 1996, new frames were produced by digitally tracing over still frames from existing footage and filling them with softer colors.  This reduced visible damage to the original animation.  Some frames were selectively cropped, while other frames feature new portions added to scenes that were hand drawn to conform to the designated picture ratio.
