How to Change Video CBR to VBR, Variable BitRate to CBR on PC/Mac
What are CBR and VBR?
What is CBR? What is VBR? What are the differences between CBR and VBR, and what are their advantages and disadvantages?
CBR is short for Constant BitRate. For instance, if you set CBR of a video to 5Mb/s, this video file will be encoded at 5 megabits per second all over. For some sections that is easy to compress, such as a shot from a tripod with almost no movement in the subject matter, this would be enough, so the output video will still look good. However, for other sections with more motions that are difficult to compress, more bits per second would be better.
VBR is the abbreviation of Variable Bit Rate, literally meaning no constant BitRate. Different bitrates will be distributed to audio video data during compressing the file. So it is a way to combine quality with file size.
The advantage of VBR is that it uses the available space more efficiently. As it can use more bits per second for the difficult stuff there will be less artifacts in the video. The merits of CBR are fast compressing speed, and great compatibility with most software and devices, while the disadvantage is the large space taking. Therefore, it has been replaced by VBR gradually.

Constant BitRate - CBR is useful for streaming multimedia content on limited capacity channels since it is the maximum bit rate that matters, not the average, so CBR would be used to take advantage of all of the capacity. CBR would not be the optimal choice for storage as it would not allocate enough data for complex sections (resulting in degraded quality)....
Variable BitRate - VBR files vary the amount of output data per time segment. VBR allows a higher bitrate (and therefore requires more storage space) to be allocated to the more complex segments of media files while less space is allocated to less complex segments...
