The term variable bitrate (VBR) refers to a bitrate control technique, and it is commonly used in sound or video encoding.

VBR is used to achieve improved video and audio quality in comparison to file size ratio. Depending on the complexity of the media the bit rate is continuously changed during the encoding process.

As opposed to constant bitrate (CBR), VBR files vary the amount of output data per time segment. VBR allows data to be transferred at a higher bitrate, with more storage space for more complex media segments and less space for less complex media segments.

Although VBR encoding requires more processing time than CBR, for most video content it produces superior visual quality

Bitrate is the number of bits that are processed when sending files, and the transfer rate of the data that makes up a media signal. It is normally measured in seconds. For video, this is typically measured in megabits per second (or Mbps, or Mb/s); with audio, it is usually is measured in kilobits per second (or kb/s or kbps).

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:

Variable bitrate (VBR) is the recommended bitrate used in sound or video encoding. Unlike constant bitrate (CBR), VBR files vary based on the amount of output data in a given media segment. CBR encoding control maintains a set bitrate over the entire video clip.

With VBR, the average transfer rates may be calculated to determine the average bitrate for a file.

Whenever you encode a video file for streaming distribution, you need to choose a bitrate with a bitrate control technique.

The issue with using CBR is that since the same bitrate is applied to the entire file it often limits the potential image quality, particularly for more complex video. CBR delivers lower overall quality than VBR. And it introduces the potential for dramatic transient quality issues.

The advantage of VBR is that it produces a better quality-to-space ratio compared to a CBR file of the same data. The bits available are used more flexibly to encode the data more accurately.

The primary disadvantage is that, as mentioned above, VBR may take more time to encode. In the past, some players could not decode variable bitrate files properly, but the vast majority of players support it. As VBR encoding algorithms have improved, most of the problems have been resolved.

When encoding video you have a choice of which bitrate and bitrate control technique you are going to use.

Unless there is a specific reason for using CBR, we recommend that you choose VBR.

VBR produces significantly higher quality at similar bitrates. The primary benefit of VBR encoding is that it allocates a higher bitrate to the more complex segments of media files and lower bitrates to the simple segments.

The primary downside of VBR encoding is that it requires more processing time, but the superior visual quality should more than make up for the extra effort.

Constant bitrate (CBR) encoding is typically not the best choice for streaming. Encoding video with CBR comes at the expense of quality, because it requires the compression engine to assign bits to content based on time rather than by image or sequence complexity.

Occasionally, compression requirements mandate that you use CBR. One example might be live event video streaming. Another example is satellite television broadcasts, in which many channels are multiplexed into one transport stream that has limited bandwidth.

Many Mac computers have a built-in FaceTime or FaceTime HD camera located near the top edge of the screen. The camera automatically turns on when you open an app — such as FaceTime or Photo Booth — or use a feature — such as Markup or head pointer — that can use the camera.
