In short,
user@somewhere$ ffmpeg -i sample.ts -acodec copy -vcodec hevc_nvenc -preset hq -tier high -level 5.0 -vf "yadif=1" -b:v 8M -pix_fmt p010le -colorspace bt709 -color_trc bt709 -color_primaries bt709 -color_range pc songs_cut_HEVC.ts
Actually , for HDTV content, 1080i, Level 4.1 should be enough to cover most of cases. Of course, Higher the level, can load more samples.
It is surprised that, NVIDIA really has been improving GPU transcoding for years. Of course, there are people not really agree, I think 12-bit HEVC or even AV1 accelaration will be included very soon.
