  • FFMPEG - Add (white, color-less, analog) grain to the video without desaturating video itself

    2 December 2018, by dd_code

    I am working on old videos where I am basically converting them to HVEC and sharpening, so i.e. my command can look like this

    .\ffmpeg.exe -i F:\file.mkv -vf unsharp=3:3:1.5 -c:v hevc_nvenc -qp 27 -a:c copy file_new.mkv

    inherent problem with this is, of course that with reducing bitrate and sharpening every now and then I can notice some nasty artifacts around the edges and on at plain-color objects.

    I noticed with some older, many times remastered movies/series that they have quite a lot of grain in the video, so I was thinking - what if I add grain and help it to mask the compression and sharpening artifacts?

    After bit of searching I got to
    https://ffmpeg.org/ffmpeg-filters.html#noise
    and now I am using this command

    .\ffmpeg.exe -i F:\file.mkv -vf unsharp=3:3:1.5,noise=alls=14:allf=t+u -c:v hevc_nvenc -qp 30 -a:c copy file_new.mkv

    however this has one big problem, it is merely a digital RGB noise, is there a way to make it desaturated, analog-ish? I tried adding h=s=0, however this is applying 0 saturation to the video track as a whole. Is there an effect which would achieve this or is there a way that I can reduce the saturation only of the very effect which then gets to "overlay" the video track, so the track would not be touched?
