2016/11/18 -CRF allows the QP to go up for frames with a lot of motion or down for still frames resulting in a consistent perceived quality while keeping the compression ...

2022/1/30 -Lower CRF/QP values do result in higher quality than high values, but this "quality slider" only works when the preset (and maybe some other ...

VBR/CBR/ABR/CABR/Per title/Constant QP/CRF are rate control modes that affect the bitrate of the output video stream.

2017/2/24 -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.

2019/8/9 -NVEnc has an actual 'Constant Quality' mode equivalent to CRF (by setting 'rc=vbr' and 'cq' instead of 'qp' - note also, it seems to necessary ...

2023/9/23 -If the profile is High 4:4:4 Predictive you can use -crf 0 to create a lossless video, otherwise use -qp 0 (High 10 profile does not support ...

2006/11/17 -In x264, there are two modes of "known quality", Constant Quantizer (CQ) and Constant Quality (aka CRF, Constant Ratefactor).

2020/6/1 -CRF versus Constant QP. CRF is a “constant quality” encoding mode, as opposed to constant bitrate (CBR). Typically you would achieve constant ...

2023/5/25 -CRF breaks the "mosaic" of the image. CQP makes the result much closer to the original. I tested on several images. Example: Codec: x264, 0.164.

2019/6/15 -The short answer is: no, you are not likely to get visual benefits, or at least none that most people will notice.
