[Update video] Video conversion key frame becomes blurred

CPU i5-9400 
GPU  NVIDIA GTX 1660s


ffmpeg -i ss11.mp4 -strict -2 -qscale 0 -intra -c:v h264_nvenc ss111.mp4


I converted the mp4 video clips into key frames, using the above hardware and commands, the video became very blurred after the conversion. The video bit rate is very high and should not be the case.
