Comment (by Anton1699):

 This is the relevant part of `ffmpeg -h filter=scale`:
 {{{
 -sws_dither        <int>        E..V....... set dithering algorithm (from
 0 to 6) (default auto)
      auto            1            E..V....... leave choice to sws
      bayer           2            E..V....... bayer dither
      ed              3            E..V....... error diffusion
      a_dither        4            E..V....... arithmetic addition dither
      x_dither        5            E..V....... arithmetic xor dither
 }}}

 Looks like `auto` isn't a valid value. I guess you could try `-sws_dither
 0` instead.
