[FFmpeg-user] UDP NVENC HEVC transcoding

I'm transcoding/resizing some UDP live streams using CUVID and NVENC. It
works but I got the feeling could be better, this is the my command line:

ffmpeg -vsync 0 -hwaccel cuvid -c:v h264_cuvid -resize 1280x720
-drop_second_field 1 -i udp://
-crf 30 -c:a -c:v hevc_nvenc -profile:v main -pass 2 -rc vbr -maxrate 3M -f
mpegts udp://

I'd like to ask for some expert advice on what could be added or
suppressed to improve it.
