  • FFmpeg film grain

    21 août 2019, par Some1Else

    I want to add a film grain effect using FFMPEG if possible.

    Taking a nice clean computer rendered scene and filter for a gritty black and white 16mm film look. As an example something like Clerks https://www.youtube.com/watch?v=Mlfn5n-E2WE

    According to Simulating TV noise Ishould be able to use the following filter

    -filter_complex "geq=random(1)*255:128:128;aevalsrc=-2+random(0)"

    but when I add it to my ffmpeg command

    ffmpeg.exe -framerate 30 -i XYZ%05d.PNG -vf format=yuv420p -dst_range 1 -color_range 2 -c:v libxvid -vtag xvid -q:v 1 -y OUTPUT.AVI

    so the command is now

    ffmpeg.exe -framerate 30 -i XYZ%05d.PNG -vf format=yuv420p -dst_range 1 -color_range 2 -c:v libxvid -vtag xvid -q:v 1 -y -filter_complex "geq=random(1)*255:128:128;aevalsrc=-2+random(0)" OUTPUT.AVI

    I get the message

    Filtergraph ’format=yuv420p’ was specified through the -vf/-af/-filter option for output stream 0:0, which is fed from a complex filtergraph.
    - vf/-af/-filter and -filter_complex cannot be used together for the same stream.

    How can I change my ffmpeg command line so the grain filter works ? Additionally, can I add a slight blur too ? The old 16mm looks more like blurred then grainy.

    Thanks for any tips.
