Enabling 10Bit FFMPEG encoding using NVENC

Hi All,
I am using the below command for encoding a raw 4k video in 10Bit
ffmpeg -f rawvideo -s:v 3840x2160 -r 120 -pix_fmt yuv420p -i YachtRide_3840x2160_10BIt.yuv -vcodec hevc_nvenc -profile:v main10 -preset hp -cq 10 -g 150 outputhp1.h265

The raw video contains 600 frames, but the encoding is happening for 1200 frames, can someone please guide me with proper command line arguments for 10Bit encoding using FFMPEG & NVENC.

Thanks in Advance

hello, any result to this ?
