Currently, most AV1 encoders have a CRF mode that should have better control over quality than just using a static QP value.

Currently, when using svt-av1 (FFmpeg), adjusting the “Quantizer” slider when in “Constant Quality” mode seems to adjust the QP value, which is not bad, but utilizing CRF instead would be the ideal.

Perhaps a good idea would be to introduce a separate selectable mode, like “Constant Quantization”, for those who want to specifically use a static QP value, while keeping the “Constant Quality” mode to CRF.
