[FFmpeg-user] [NVIDIA] Video conversion key frame becomes blurred

ffmpeg -i ss11.mp4 -strict -2  -qscale 0 -intra ss111.mp4
ffmpeg -i ss12.mp4 -strict -2  -qscale 0 -intra ss112.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.
