I actually work like that. I check the Arri LUT, sometimes it gives me a good result, but many times it
looks wrong, too contrasty, colors become to blue and other oddities.
On this job, I have a few clips that took the Arri LUT nicely, and many others that I correct myself.
As you say, first node is for primary and overall level and than more tweaks.
I worked like that in a few cases before and noticed Resolve’s, or my system config + Resolve, “lack of color space” behavior, and I actually thought this is because I don’t have a Panel,
but this project is too much, this is close to unusable.
Maybe it’s the version 10 beta?
But again, I did 2 jobs before this and it behaved flawlessly.
