The LUT is compatible in conjunction with all cameras and videos (Sony, Canon, Panasonic ...) since it's more of a look rather than a real LUT therefore it's compatible with the Cinelike footage you have from your GH5 and even Canon videos!
You can also play around with the settings of your Sony Picture Profiles. Sometimes I achieve stunning results by adding a few minor adjustments.
This package comes with the .cube file, which works flawlessly with Premiere Pro.
A few customers have had issues with the application with FCPX however it is expected to work with a LUT Loader.
Keep in mind that this isn't Log LUT!
