Just played with 3D LUT files create from instruction link of Displaycal. Take sometime to read, try, research and understand. I’ve try that 3D LUT of my display on Davinci seem to work I think.
Your another link sound great! Will read tonight and maybe comeback with few questions. 
In meantime, I found strange behavior of LUT(3D) filter.
- Once open 3D LUT file in LUT(3D) filter, when click any other filter then click back again at LUT filter, it say “No file Loaded”, it unload automatic. Don’t know why. Also change layout ex: from color layout to editing layout back and forth, “No file Loaded” in filter.
- Some 3D LUT file seem to not working in Shotcut. Since I’ve create few difference 3D LUT files, some also come from Davinci build-in LUT, only few of them effect in Shotcut. Davinci effect every
LUT files but Shotcut only some will effect. Why?
