ARRI Color Tool (ACT)

The reference tool for ARRI Look File 2 (ALF-2) - ARRI Color Tool is a free utility for creating the ARRI Look File 2 for ALEXA SXT, 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 QuickTime ProRes clips or Log C *.dpx grabs from all ARRI cameras. To facilitate the ALF-2 in 3rd party post processing tools, which do not support the ALF–2, the Color Tool provides the option to export ALF-2 looks as 3D LUTs.The ARRI Color Tool is available for Mac OS X 10.8 Mountain Lion, 10.9 Mavericks/10.10 Yosemite and 10.11 El Capitan and Windows x64 (beta).

New features of ACT 1.4.0.1 : 

  • ARRI Look File 2 (ALF-2) format for ALEXA SXT cameras
  • Support of new wide gamut colors spaces (REC 2020, P3 DCI, P3 D65, P3 D60) in ALEXA SXT cameras.
