Rate controlRate control is a setting within an encoder that determines how the encoder will function. There are four modes of rate control:
• CBR
• VBR
• CQP
• Lossless
More is a setting within an encoderAn encoder is a tool that processes a computer screen, webcam, or camera and, in the case of broadcasting, transmits it to an ingest server. Alternatively, it will convert the processed image and audio data into a filetype for recording.

- CBRCBR stands for constant bitrate. It is a rate control method used to determine how a broadcast or recording is encoded. The advantage of CBR is that the encoder will conform to the limit you set. This makes CBR the best rate control method for live streaming, which operates on a strict bitrate limit. More
- VBRVBR stands for variable bitrate. It is a rate control method used to determine how a broadcast or recording is encoded. The advantage of VBR is that the encoder will conform to the bitrate needs of the video within the defined minimum and maximum bitrate values. This rate control method is best used for recording video when storage of raw footage is at a premium. More
- CQPCQP stands for constant quality profile. It is a rate control method used to determine how a broadcast or recording is encoded. The advantage of CQP is that the encoder will allow as much bitrate as necessary to meet the defined quality settings, ensuring consistent video quality throughout the entire recording. This rate control method is best used for recording content where a consistent video experience is desired. Be warned: CQP video file size can be very large. More
- LosslessLossless is a Rate Control setting that will give the encoder as much bitrate as necessary to record or broadcast content at its original quality level. This results in astronomically large file sizes, so use this setting with caution. More
