Hi,
I'm using ffmpeg for a long time, but I've just recently started to
use it with 10bit HDR (HDR10) video.
So far I found out how to re-encode HDR10 video with libx265 and
retain the HDR metadata. It's a bit complicated, but it seems to
work fine. However, I'm unsure about video filters.
In particular, I often use the atadenoise filter. It works really
well for 8bit SDR video. But can it be used with HDR10 video, too?
Can I simply add ''-vf atadenoise`` to the command and it'll work,
or will it clip the data down to 8bit? Is there anything else that
I need to take into account?
Best regards,
Oliver
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
