![]() ![]() ![]() Results unpredictable if not applied to LOG footage. Now LUTs have become a lazy starting grade. LUTs were originally designed to mimic specific film stocks when applied to LOG footage. With 8-bit cameras the image might suffer from compression/expansion. With high bit rate cameras (10, 12 or 14 bit color) this can be corrected in post to a full tonal range without much image degradation. LUTs were developed to use with "LOG" footage, which is more or less a way of recording footage in a reduced dynamic range, crushing things towards middle gray to avoid highlight and shadow clipping. And it actually is as brute force as remapping value X to Y. Let's say, for example taking all light grey values and remapping them to a light orange. LUT="Look Up Table." What the LUT actually does is a remapping of color values. Let me back this discussion up to basic definitions. If you find, download and use the Technicolor Cinestyle profile for Canon DSLRs then there is a utility for that. The result in their interpretation of what "standard" is. The Utility folders have various LUTs to convert from some specific camera Log format to a supposed "standard" video setup (a normal contrast and color curve). ![]() So the generic Log LUT could still work maybe close enough. There are so many specific camera log curves out there but they vary my smallish amounts. The Log folder assumes a generic log contrast curve. Of course every camera outputs what they think is pleasing contrast and saturation. So normal means something like pleasing contrast and saturation. What you probably want to use are the LUTs in the "standard" folder. They assume a starting point like I previously mentioned. What you use depends on your source material. ![]()
