|The RMVB file extension is related to RealMedia. A RMVB format is a variable bitrate extension of the RealMedia multimedia container format developed by RealNetworks.
Variable bit rate (VBR) encoding is optional. It gives more bandwidth to scenes that are hard to compress, and less to scenes that are easy to compress. It can also keep video quality high by taking advantage of some of the streaming bandwidth reserved for network overhead.
VBR encoding generally provides video quality superior to that achieved through constant bit rate (CBR) encoding, making the most difference in videos that have a mix of high- and low-action scenes. VBR encoding is not used with SureStream, and RealVideo VBR clips used the file extension .rmvb.
