The bottom line is that CBR is more consistent and reliable for time-sensitive encoding, and VBR produces higher-quality results. It is important to use the appropriate option for your specific streaming needs. Final ThoughtsĬBR and VBR play different roles in online video streaming. CBR also produces higher-quality streams than VBR, making them ideal for large audiences that consume live content online like sports games or concerts. That’s because the constant bitrate is more reliable for encoding video content in real-time. We recommend using CBR for live broadcasting with YoloBox and YoloBox Pro. Recommended Encoder Settings for Live Streaming with YoloBox ![]() While ensuring the highest compression rate in a single encoding, each frame is allocated enough bits to achieve the required visual quality. This is because it can take longer to process the data.Ĭonstant Quality aims at achieving a fixed visual quality. The fluctuating aspect of this method of encoding makes VBR best suited for on-demand video transcoding. In terms of encoding, data is output at a set rate per time segment, and variable bitrate is measured by taking the average bitrate of the entire file. All you have to do is realize the difference between the terms ‘constant’ and ‘variable.’ In other words, regular bitrate and variable bitrate are concepts with exactly opposite meanings. The term itself suggests its functionality. The abbreviation VBR stands for variable bitrate. The consistency of CBR makes it well-suited for situations where video content must be encoded in real-time. Since it is so popular in the live streaming industry, constant bitrate is the most compatible option. ![]() If you are streaming video or audio using CBR encoding, the data required to provide that service is set at a constant data rate.ĬBR is preferred in many streaming situations because it has been the standard in online video streaming for some time. The acronym CBR stands for Constant Bitrate. ![]() This blog defines the terms and provides recommendations for when to use all three. There are three options in YoloBox: constant bitrate encoding (CBR), variable bitrate encoding (VBR), and constant quality (CQ). Streaming with a higher bitrate helps you produce higher-quality streams. In online video streaming, video bitrate is measured in kilobits per second, or kbps.
