All of our LUTs have been created with the standard Rec.709 gamut/gamma (default for most cameras) in mind and therefore, they will work with ANY footage.
Of course, you can also use our LUTs on a Log-recorded video but you'll need to use two instances of the mLUT plugin: the first one with the "Log to Rec.709" utility LUT designed for your camera (they are free and are included with the mLUT plugin) and the second one to apply the creative LUT of your choice.
