What does vbr mean

Quality-based VBR encoding: The focus is on a specific quality level for the media stream and not the bit rate. This encoding also ensures that the generated file has a consistent quality.

However, because this encoding cannot provide required size and bandwidth criteria, it may not be suitable for those with restricted memory or bandwidth, like portable media players. Unconstrained VBR encoding: This makes use of two encoding passes. Unconstrained VBR encoding's main advantage is the ability to provide the highest quality for the compressed stream, while remaining within an assumable bandwidth. Using the maximum values, the codec then determines and compresses the data. By: Justin Stoltzfus Contributor, Reviewer.

What is the full form of VBR? The term bitrate , also written as bit rate , gets tossed around a lot in mobile development, so it might be good to go over some common terminology: VBR stands for variable bitrate , a control technique which allows the bit rate to vary, but maintains the quality. CBR stands for constant bitrate , a control technique which keeps the bitrate constant, but allows video quality to vary.

MBR stands for maximum bitrate , a control technique which allows the bit rate to vary, but only up to a maximum value. ABR stands for adaptive bitrate , a video segment management technique which delivers different quality levels of video to the client based on network capability at a given time. It is different than the three bitrates terms above that relate to controlling the bitrate. Translate Variable Bit Rate to other language.
