  • Change gray pixel to black pixels in video

    12 janvier 2023, par yabru

    I want to change every gray pixel in my video with the (r,g,b) 158,158,158 to black 0,0,0

    


    I've tried the solution of THIS post, but backwards. I just do not understand the syntax.

    


    ffmpeg -y -I my_video.mp4 -c copy -c:v libx264 -preset ultrafast -vf "yadif,format=rgb24, lutrgb=r='if(eq(val,158),0,val)':g='if(eq(val,158),0,val)':b='if(eq(val,158),0,val)'" my_video_fixed.mp4

    


    ^ doesn't change anything

    


    could anyone help me modify my command (with an explanation of the solution) :)

    


    version : ffmpeg version 5.1.2
