Hi, do your comps in AE in 32 bit. Use the cineon converter, not a LUT. Do all your work in linear then convert it all back to log as the final step. To get a closer visual idea of what it is going to look like once filmed out, use the color profile converter effect (I think it’s called that). I can’t remember the exact settings off hand but there are profiles for viewing film.
Good luck
