CBR vs VBR: Surveillance Streaming by John Honovich, IPVM posted on Jan 17, 2012 About John Contact John How you stream video has a major impact on quality and bandwidth. Typically, when people think streaming or encoding, CODECs such as H.264, MPEG-4, etc come to mind. However, regardless of the CODEC, one still needs to choose how the video stream handles changes in scene complexity. This is where streaming modes such as CBR and VBR come into play. They have a major impact on quality and bandwidth consumption. In this report, we provide a tutorial and recommendation on how to optimially choose and use streaming modes. CBR vs VBR Choosing between CBR and VBR modes is typically overlooked: CBR stands for constant bit rate and like the term implies aims for a constant or unvarying bandwidth level VBR stands for variable bit rate and like that term implies allows the bit rate to vary You need to determine whether and how much you will allow the bit rate lev
