[3] Kai features remastered high-definition picture, sound, and special effects as well as a re-recorded voice track by most of the original cast.
To convert the 4:3 animation to 16:9 widescreen, some shots were selectively cropped while others feature new hand drawn portions; an uncropped 4:3 version was made available on home video and international releases for the first 98 episodes.
Much of the anime-original material that was not featured in the manga was cut from Kai (ultimately abridging the 291 episodes of Dragon Ball Z down to 159 in Japan and 167 internationally).
[3] The international version of the 2014 series was titled Dragon Ball Z Kai: The Final Chapters by Toei Europe and Funimation,[7] and had initially only been earmarked for broadcast outside of Japan.
[8] The home media releases of The Final Chapters contain a Japanese audio track for all episodes, including those that were never broadcast in Japan.
