SBC relied on two main technologies to achieve this improved efficiency: Multipass encoding and Variable Keyframe Intervals (VKI).
SBC ceased to be commonly used after XviD and DivX development progressed to a point where they incorporated the same features that SBC pioneered[citation needed] and could offer even more efficient video compression without the need for a specialized application.
Files created by SBC are compatible with DivX 3.11 Alpha and can be decoded by most codecs that support ISO MPEG4 video.
[citation needed] The DivX 3.11 Alpha codec allowed a user to control three aspects of the encoding process: the average bitrate, keyframe interval, and whether the codec preserved smoother motion or more detailed images.
Nandub was a modification of the open source VirtualDub video encoder performed by Nando that incorporated SBC features.
