 the resulting .mkv still has

 {{{

 show with ffprobe. 6.2 seems to be the auto level which currently is the
 highest. I tried all sorts of integer but it always ends in the same.

 ffmpeg -h encoder=hevc_amf shows the following about level
 {{{
   -level             <int>        E..V..... Set the encoding level
 (default auto) (from 0 to 186) (default auto)
      auto                         E..V.....
      1.0                          E..V.....
      2.0                          E..V.....
      2.1                          E..V.....
      3.0                          E..V.....
      3.1                          E..V.....
      4.0                          E..V.....
      4.1                          E..V.....
      5.0                          E..V.....
      5.1                          E..V.....
      5.2                          E..V.....
      6.0                          E..V.....
      6.1                          E..V.....
      6.2                          E..V.....
 }}}

 so I even tried numbers like 50 in the hopes it means "5.1", as I do not
 understand how the 14 current options listed above are represented by
 integer number between 0 und 186 (which says so in the help). I tried both
 left the labels 5.0, 5.1, 4.0, even 1.0 as well as differnt integer
 numbers in between 0 and 186. Everything ends in Main at L6.2
