 Summary:
 An LUT (HueVsHue and HueVsSat corrections) exported from DaVinci Resolve
 does not seem work in Ffmpeg.

 The LUT does work in Shotcut, expect when there is any overlay (PIP or
 watermark etc). I tested the LUT in OBS and it didn't work at all.

 Notice, that the LUT's effect is not dramatic. However the effect is
 clearly visible in vectorscope. Links to expected and actual outputs are
 linked below.
