What is the difference between CBR and VBR encoding?

Constant bit rate (CBR) encoding persists the set data rate to your setting over the whole video clip. Use CBR only if your clip contains a similar motion level across the entire duration.  CBR is most commonly used for streaming video content using the Flash Media Server (rtmp)
Variable bit rate (VBR) encoding adjusts the data rate down and to the upper limit you set, based on the data required by the compressor. VBR takes longer to encode but produces the most favorable results.  VBR is most commonly used for http delivery if video content (http progressive)
We recommend you do not use CBR unless you have a specific need for playback on a device that only supports CBR. Our default VRB mode will produce higher quality  at competitive bitrates.
