MadVR supports four different 3DLUT files. If you don't know what madVR is or how to set it up and use it go here (). MadVR is a DirectShow video renderer created by madshi. Below are instructions on how to use them. (2)Use your 3DLUT file(s) with madVR, t3dlut or rgb3dlut, the software options which support 3DLUT files. (1)Read the detailed instructions inside the Manual and create 3DLUT file(s) that fit your needs. Changed Input/Output_Primaries range to allow negative numbers in R,G,B New command Denoise_Black_Level to denoise black level range Handles R'G'B', RGB, Y'CbCr and YCbCr video data HD, SD, xvYCC, sYCC & Computer video standards Since all the computing is performed offline its precision can be increased by using 64bit floating point (per component) through out all the conversion chain. This way, the conversion can be performed at runtime using lower computational power and leaving more CPU available for other tasks. The computed 3D LUTs (three, one for each component) are then written to a file which can later be used, when playing videos or viewing photos, simply by mapping the input data through the 3D LUTs. When using 3D LUTs all computing is performed offline during its creation. The idea of using 3D LUTs was due to the intensive computing that needs to be performed when converting video data between different color spaces. You can read a little more about CMS here (). YCMS is a Color Management System (CMS) that uses 3-dimensional lookup tables ("3D LUTs") to perform the conversion between the input and output color representations.
