I am not aware of a built in LUT for Arri. I do recall Sony S3 Gamma LUTs magically applied with the ama preference set to auto apply LUTs with ama links. Are these LUTs in the source settings Pulldown menu? When I to the Color LUT Effect I only saw the LUT we imported from Resolve. Perhaps I didn't delve deep enough in the path.
Would the choice of Project, Shared or Both when importing a LUT have an effect on seeing it as a choice with the Color Lut effect?
I will have to go back and check the system I was on yesterday.

It raises all kinds of questions as to what would best resemble the performance of the Arri LogC to Rec 709 I'm use to applying in Resolve. I use the 3D LUT in Resolve and it gives me a nice starting point when baking out Avid DNX.
As I google around there are suggestions that 1D LUTs are better if not changing color space. I had always used the 3D LUT because I thought it was more accurate but honestly I'm not aware of all the subtle differences. I had never thought about what color space the Arri was shooting but I assumed LogC was a different color space than Rec 709 but now I'm wondering. I just want to undo the LogC back to Rec 709 so is that better with a 1D or a 3D LUT.
Either I am making this more difficult than it is or it is more complicated than meets the eye. I just want to un LogC the footage like I do in Resolve when I use Resolve's Arri LogC to Rec 709 Output LUT. That isn't hard in Resolve but I have never had to start making tweaks for it to have satisfactory results.

Subject: [Avid-L2] 3D Hard LUT vs. Soft LUT What The LUT?
Attempting to bring the Arri LogC to Rec 709 LUT from Resolve into Avid I found Avid would not import the .dat file in the Resolve LUT folder. I went to the look up table setting page in Resolve and generated a LUT based on the Arri LogC to Rec 709. This created a .cube LUT that Avid would import. The automatically generated name said "soft" in the title. I had not check the scale to levels box which I"ve read leads to a hard clip at the upper and lower values which 940 and 64 for 10 bit. I didn't know to address these settings when generating the LUT. If I left the settings at 0% softness on the upper and lower clips isn't that in essence a hard clip. Things seem to be looking good but this was on a system without a scope so I don't have a real way to check things.Is there a way in Resolve to generate a LUT based on it's internal Arri LogC to Rec 709 that isn't soft?John Moore Barking Trout Productions Studio City, CA bigfish@...
