 I'm using FFmpeg to convert some video files shot in Slog3 with a Sony A7S
 III camera. I just discovered that I get different results using the
 command below on FFmpeg versions 5.1 and 5.0.1.

 This is the command I'm using:

 {{{
 % ffmpeg -i input -map 0:0 -map 0:1 -c:a aac -ab 320k -c:v libx264 -crf 15
 -s 960x540 -pix_fmt yuv422p10le -profile:v high422 -preset fast -g 1
 -color_trc log_sqrt -color_range jpeg output
 }}}

 I'm on Windows 10, and I'm using the builds coming from CODEX FFMPEG
 (https://www.gyan.dev/ffmpeg/builds/).

 You can see an animated comparison of the results I'm getting here:
