Comment (by Robert Horstmann):

 @haihao Thanks again !
 Unfortunately, it does not work ... -setting "-compression_level 16"
 causes garbled, defective video in the output mkv.

 My command line qith compression_level 16:
 /usr/local/bin/ffmpeg -vaapi_device /dev/dri/renderD128 -i "FILE0165.MOV"
 -vf format=nv12,hwupload -c:v hevc_vaapi -compression_level 16
 -global_quality 32 -c:a copy -threads 0 -y 32_16_hevc.mkv

 This command line provides proper output:
 /usr/local/bin/ffmpeg -vaapi_device /dev/dri/renderD128 -i "FILE0165.MOV"
 -vf format=nv12,hwupload -c:v hevc_vaapi -compression_level 32
 -global_quality 32  -c:a copy -threads 0 -y 32_32_hevc.mkv

 I could share more data if you would like to investigate / troubleshoot.

 KR,
 Robert
