I use this filter :

#*1.0 to 1.8 for 720p video and 1.0 to 4.0 for 1080p*
#for f in *.mp4; do ffmpeg -y -i "$f" -vcodec libx265 -crf 26 -preset
slow *-vf nlmeans="1.4:7:5:3:3"* -c:a copy "$(basename "$f" .mp4).mkv";done
#for f in *.mp4; do ffmpeg -y -i "$f" -vcodec libx265 -crf 21 -preset
slow *-vf nlmeans="2.5:7:5:3:3"* -c:a copy "$(basename "$f" .mp4).mkv";done

You can check the result via mediainfo :

sudo apt install mediainfo-gui
