The SDK aims to overcome the fact that GameCube's game discs can hold only 1.3GB of data, limiting the amount of video available for games, etc to very minimum -- when compared to PS2 and XBox which both can use DVD discs, upto 8.5GB per side when using dual layer discs. Traditionally games use MPEG-2 encoded video, just like DVD-Video does, but by allowing developers to use MPEG-4 instead, the video bitrate can be significantly lower and still maintain decent video quality.
