INSTALLATION AND OPERATION MANUAL CNVETX1 VBR files vary the amount of output data per time segment. VBR allows a higher bit rate (and therefore more storage space) to be allocated to the more complex segments of media files while less space is allocated to less complex segments. The average of these rates can be calculated to produce an average bit rate for the file. The advantages of VBR are that it produces a better quality-to-space ratio compared to a CBR file of the same size.

INSTALLATION AND OPERATION MANUAL CNVETX1 The advantages of VBR are that it produces a better quality-to-space ratio compared to a CBR file of the same size. The disadvantages are that it may take more time to encode, as the process is more complex, and that some hardware might not be compatible with VBR files. In Constant Q mode only Q Initial is entered. This mode is intended to keep a constant quality. A low Q setting will generally have a high bit rate providing high quality.
