Hi, LUTs created with Look Converter are good. Files are light (around 60Ko, when the original 3D 64 LUT is 7Mb) because LUT generated is a 3D 17 LUT.The higher is the LUT (8, 17, 32, 64, ...), the more there is color accuracy.

Look Converter will generate a neutral filter (like the attached file).
You'll have to load this neutral filter image into Lightroom (or even Instagram) and apply your presets.
Then, Look Converter will generate a LUT from the difference between the neutral filter color values and the modified one.

Let me know if it's not clear 

It was clear on how to create my own lut with the program (thank you for that!), but it wasn't clear to explain on what kind of image i could use that.
As example of my question, imagine if i have a timeline with a7s images (not s-log) and a gh4. What do a have to do before applying this LUT on images of both cameras?
What's the best starting point to use this kind o luts?

Thank you!
