  • colored TV-Noise with windows

    8 janvier, par LookAndSee

    I have some question to the colored noise at image 2 of the following thread :

    


    Simulating TV noise

    


      

    • how can i get this in windows ? I like a random pattern consisting of red, green, blue, white and black points, like 255:0:0, 0:255:0, 0:0:255, 255:255:0, 0:0:0 and 255:255:255 - no pink, no orange, no cyan ... at the first step.

    but random in all 3 places always delievers (with ceil, floor or round) whole black, or whole white or bw-noise :-(
does it mean, the random(1) per point is 3 times the same in one computing-cycle ?

    


    Any suggestion ?

    


    This is what i tried :

    


    ffmpeg -y -f lavfi -i nullsrc=s=1280x720 -filter_complex "geq=r=(round(random(1)))*255:g=(round(random(1)))*255:b=(round(random(1)))*255;aevalsrc=-2+random(0)" -t 5 output.mkv
