title: 10bit HDR To 10bit SDR Conversion With FFmpeg
body: <p>I know how to convert 10 bit HDR video to 8 bit SDR with FFmpeg, but i wonder if FFmpeg can do 10bit HDR to 10bit SDR conversion.</p>
  
  <p>I always use this command line for my video conversions:</p>
  
  <pre><code>.\ffmpeg.exe -i input.mkv -vf zscale=t=linear:npl=100,format=gbrpf32le,
  zscale=p=bt709,tonemap=tonemap=hable:desat=0,zscale=t=bt709:m=bt709:r=tv,
  format=yuv420p -c:v libx265 -crf 10 -preset fast output.mkv
  </code></pre>
  
  <p>Is it possible?</p>
