Quality can be further improved upon by adding options such as B-frames (limit this to 3, at most, and this requires the H.264 Main profile and above.
Note that the -cq scale is logarithmic, meaning that 0 is essentially lossless and 51 would be the absolute worst. See this write-up for more on what CRF does. 19 is the recommended setting as its' visually identical to 0, yet preserves good compression trade off to file size. Of course, you'll need to adjust for target bit rates and a fixed cq value. For CRF-based encodes, pass the following arguments in the snippet below to FFmpeg: -c:v h264_nvenc -rc:v vbr_hq -cq:v 19 -b:v 2500k -maxrate:v 5000k -profile:v high
