ARRI Color Tool is a free utility for creating the new ARRI Look File 2 for ALEXA LF, ALEXA SXT, ALEXA 65, ALEXA Mini and AMIRA cameras. You can use the ARRI Color Tool to create a completely new look or modify an existing look based on Log C Apple ProRes clips or Log C *.dpx grabs from all ARRI cameras.
Some 3rd party post processing tools do not support ALF-2 looks natively. ACT allows one to export 3D LUTs in order to be compatible with these tools. ACT is available for Mac OS X and Windows x64.
