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 ![]()
