Smart Bitrate Control, commonly referred to as SBC, was a technique for achieving greatly improved video compression efficiency using the DivX 3.11 Alpha video codec or Microsoft's proprietary MPEG4v2 video codec and the Nandub video encoder. 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 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.

Diz: Honest? Why, we’re the only ones who can afford to be honest in what we tell the voters. We don’t have to be re-elected like politicians.”

“Being a parent is such serious business that we dare not take it too seriously. Children are inherently funny. So are parents. We all are at our funniest when we are desperately struggling to appear to be in control of a new situation.”
