ARRI Color Tool (ACT).
The reference tool for ARRI Look File 2.


New features of ACT 1.5.0.1:

  • Creating the new ARRI Look File 2 (ALF-2) format for ALEXA 65 cameras.
  • Support of the new wide gamut HDR colors spaces (Rec. 2100/PQ, Rec. 2100/HLG) ALEXA Mini and AMIRA cameras.


ARRI Color Tool is a free utility for creating the new ARRI Look File 2 for 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 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.

ACT is available for Mac OS X 10.10 Yosemite and 10.12 Sierra and Windows x64.

For questions or help using these tools, e-mail digitalworkflow@arri.de and an ARRI representative will address your concern.
