what is capped CRF in video rate control

What is Capped CRF?

Capped CRF is a video encoding technique that combines Constant Rate Factor (CRF) rate-control with a bitrate cap (or ceiling) to be able to control the video bitrate, while maintaining the video quality at the desired level. Capped CRF is quite different from VBR rate control that prioritizes quality over hitting or staying under a specific bitrate CBR rate control that prioritizes hitting a specific bitrate over quality Capped CRF has become quite popular in the video encoding sector because it allows a video encoder to achieve a balance between video quality, file size, and bandwidth limitations, is very useful in...
