On a Mac, navigate to /Library/Application Support/Adobe/Common
On a PC, navigate to C:\Program Files\Adobe\Common
Within “Common”, create a new folder called “LUTs”.
Within that folder, create two new folders called “Creative” and “Technical”.
Note: folder names are case-sensitive
Copy the LUTs to the “Creative” folder. If you have any technical LUTs such as a Log to Rec.709 conversion, you can copy it to the “Technical” folder.
Restart Adobe Premiere Pro. Your LUTs will be loaded into the Lumetri color panel for color grading.
