CRF Guide (Constant Rate Factor in x264, x265 and libvpx)

What is the Constant Rate Factor? The Constant Rate Factor (CRF) is the default quality (and rate control) setting for the x264 and x265 encoders, and it’s also available for libvpx. With x264 and x265, you can set the values between 0 and 51, where lower values would result in better quality, at the expense of higher file sizes. Higher values mean more compression, but at some point you will noti
