'''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: [[Multi-pass encoding|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|date=September 2010|reason=multi-pass encoding invented with nandub?}} 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 [[International Organization for Standardization|ISO]] MPEG4 video.{{Citation needed|date=September 2009|reason=DivX is hacked Microsoft's proprietary MPEG4v3 compression format and it is not MPEG-4 compliant.}}
